    "Of course, alternative energy sources CAN totally replace the need for burning fosssil fuels! I have heard that a 110 by 100 mile field of solar panels in the New Mexico desert would geverate enough electricity to power the entire nation. Arguments disputing the viability of clean alternative energy sources inevitably come from prople and companies that stand to lose money if fossil fuels are replaced. By the way, let's get it straight: Coal and natural gas are NOT sources of clean alternative energy!

    The real problem is not the viability of various types of clean alternative energy, it's the political will of Congress and the American people to see through the pro-oil lobby's propoganda and then take definative and strong action now."

      "well first of all Rob it does not all have to come all from one source, there could be power stations all across the US... like there is for fossil fuels!!!!!!!!!!!!!!!!! it far more reliable and far more consistent than the power supply we get from foreign countries who have threatened to cut of these supplies in the past. In one day the sun light that hits the earth is enough to meet all the worlds energy needs for an entire year, that sounds like enough power to me to be consistent. and you ask how much it will cost to build this new infrastructure? Try asking how much it will cost to keep buying oil and other products that are skyrocketing in price and later try to fix the problems these fuels would have created by the time they're gone. One just has to look at the coal industry to see how insane fossil fuels are, it actually costs more to get the coal out of the ground and burn it than the money from selling the energy produced. The only reason coal is still in business is because of government subsidies that keep it profitable."

      "I couldnt agree more, but im not completely sure about the statistic of the solar field in the desert. I believe it could produce much power, but im not sure about all of america. However, I will never rule out the fact that i believe that alternative energy can phase out much, not all, of fossil fuel consumption. With todays technology much is possible, but it just takes a large amount of finances in order to do such things. I am with alternative energy all the way."

      "Yes, you have "heard" that 11,000 square miles of solar panels will power the 4,120 billion Kilo-watts Americans use every year. Well Bob, how much will it cost to create not just a new, but a completely restructured infrastructure to handle the inconsistent energy source such as solar power that our current system is capable of? Then take those new lines that can handle that massive power load and branch them across the entire United States! Sounds "green" to me."

    "In response to your question, 'Can alternative energy effectively replace fossil fuels?', I can categorically answer in the affirmative. Our company, Genesys, LLC, patented and proven (reduced to practice) a new technology that can convert any form of water (e.g. waste, or sea water) to hydrogen effectively and efficiently. We presently have a demonstration prototype producing hydrogen from tap water with high efficiency (> 75%). The only ingredient is heat which is obtainable from geothermal or solar sources. This technology has the ability and potential of replacing ALL fossil fuels. We challenge any other competing energy technology or modality with that comprehensive solution."

    "It's not whether or not fossil fuels can be replaced. The grim reality is that it WILL be replaced eventually, even if all of the oil in the world is burned up. The benefit of switching to alternative energies now is that we won't end up in mass chaos when oil is gone."

    "There is a possible very affordable solution to our electricity generation and liquid transportation fuel problems. We could combine liquid fluoride thorium [LFT] reactors with the 'Green Freedom' synthetic liquid fuel process, which uses nuclear power to produce sulfur free gasoline and jet fuel made from water and atmospheric CO2... LFT reactors would not promote nuclear weapons proliferation and could be manufactured like airliners on an assembly line, dramatically lowering costs and enabling electricity production at a rate cheaper than burning coal. It is reported that LFT reactors produce less than 1% of the long-lived radioactive waste of conventional water cooled reactors, and could even be used to recycle our large supply of spent nuclear fuel rods."

    "Of course! Geothermal energy that is constantly renewed from the erath! Tidal and hydroelectric plants can be built. Um, the earth's surface is over 70% water people! What does that tells us as a species if we have a source of abudant energy that makes up most of the planet yet refuses to use it? Stupid maybe? How about wind power? Yep plenty of high winds in many parts of the world. There's also the freakin' sun! Something that is thousands of times larger and has vast amounts of energy. Those solar panels will come in handy any day. Or would we ratther just pollute the planet we live on and drink toxic water and eat toxic foods while choking on bad air? Sometimes I truly wonder about the "intelligence" of this species."

      "We rely so heavily on fossil fuels that it would be very difficult to switch over to the alternative energy and stop using fossil fuels. In 2007 the U.S. relied on fossil fuels to supply 85% of it's energy needs, while the renewables such as wind, solar, and biomass accounted for 7% and Nuclear power supplied 8%. That would be very difficult to shake people from fossil fuels, and the money, land, and time to mass produce all of this energy would kill us."

    "Alternative energy sources, such as wave and tidal energy, geothermal energy, wind energy, etc., are the only true solution to the world's energy dilemmas. This is because the question is not whether or not alternative energy sources could replace our energy systems now; in fact, it is actually proven that all of the energy sources that I have listed could potentially replace the energy sources used by today's world. For example, according to Arjun Makhijani, PhD, President of the Institute for Energy and Environmental Research, wind energy by itself in 12 Midwestern and Rocky Mountain States equal about 2.5 times the entire electricity production of the United States. This means that wind energy could produce greater results than of all the United States electricity supply by harnessing wind energy in just 12 states of the entire U.S. Unfortunately, the answer is not as simple as which energy source is most successful. The real question at hand, at least for those who are in charge of changing our energy consumption, is how much the economy will be affected by the change. Economic bias will continue to stall the production of more efficient energy sources for years to come."

      "Braden I feel what you're saying. It's like you jumped inside my mind and took my words and put them on this website. I like the idea of using cleaner energy like wave and tidal energy, geothermal energy and wind energy. The great part about this is that it's all renweable energy and is infinite,where fossil fuels are finite. The fact that these ways of aquiring energy could replace our dependence on fossil fuels is a great thing. Generating energy in new ways other than fossil fuels assures an amazing future."

    "Every single year we send trillions of dollars the hands of a few for every single thing we do, because oil is used to transport everything in this world outside of Iceland. This handful of corporations control the price of everything through transportation routes. No matter how you slice the cake oil will always be an oligopoly, there is a limited amount of it, and making it from scratch would be bloody expensive and a waste of time. A much better method is hydrogen. Iceland is already using this and it is expanding across the island, limiting the amount of money being sent overseas to Russia and the Middle East to dictatorships and keeping their money on the island. Also, the United States could drill, but money would continue to go to the same people who control everything, and the amount of oil is not enough to sustain our country for the rest of my life inexpensively as a 19-year old. If we invest in hydrogen today and make a network of stations across the country through tax breaks for gas stations we could have a hydrogen economy in a couple of years and stop sending money to the dictators and terrorists that hate our freedom. Plus the environmental benefits are massive. Ever been to Los Angeles? Asthma city."

    "Can alternative energy effectively replace fossil fuels? I think alternative energy sources can effectively replace fossil fuels. Some alternative sources that we can use are hydro power, solar energy, wind energy, ocean energy, or geothermal installations harvest renewable energy. "There are no other sustainable energy sources that could possibly contribute substantially to the energy needs of mankind... Without any question; the energy demand of mankind can be satisfied from renewable sources." That quote was said by Ulif Bossel and I agree with him. Using these alternative energy sources is a plus because it will help create more jobs for people, which makes people wealthier. Using alternative energy sources would also help make our planet a cleaner and greener place because there wouldn't be as much pollution since we would be using renewable energy sources. It will also be healthier for people too because we would be breathing in cleaner air."

    "I believe that alternative energy can replace fossil fuels. This will not be easy, but will ensure a safer future. We need to look at the problems fossil fuels are causing and make a change. "For too long our nation has been dependent on foreign oil... It's in our vital interest to diversify America's energy supply -- the way forward is through technology. We must continue changing the way America generates electric power, by even greater use of clean coal technology, solar and wind energy, and clean, safe nuclear power. We need to press on with battery research for plug-in and hybrid vehicles, and expand the use of clean diesel vehicles and biodiesel fuel. We must continue investing in new methods of producing ethanol -- using everything from wood chips to grasses, to agricultural wastes. We made a lot of progress, thanks to good policies here in Washington and the strong response of the market. And now even more dramatic advances are within reach. Tonight, I ask Congress to join me in pursuing a great goal. Let us build on the work we've done and reduce gasoline usage in the United States by 20 percent in the next 10 years." -George W. Bush"

    "I think that alternative energies are a great idea because using things like solar, geothermal, hydroelectric, natural gases, and wind mills, as opposed to coal, gasoline, and propane because things like gasoline pollute the Earth. "Alternative energy refers to energy sources which are not based on the burning of fossil fuels or the splitting of atoms. The renewed interest in this field of study comes from the undesirable effects of pollution (as witnessed today) both from burning fossil fuels and from nuclear waste byproducts. Fortunately there are many means of harnessing energy which have less damaging impacts on our environment," says the University of Utah Department of Civil and Environmental Engineering. I agree with the University, our society should use other sources. The US has 1.6% of the world's oil but it uses 24% of the world's oil, my opinion is that if we are using almost 25% of oil, but only producing not even 2% then that's a wakeup call that we need to slow down, and find new ways to run things using oils, gases and other harmful products. Our nuclear power plants produce waste, with radioactivity that causes cancer. Eliminating the harmful waste would not only help the environment, but also save lives!"

    "We need to change our vision of this debate. Alternative energy and a new smart grid with fossil fuel power plants acting as storage batteries could work. For example, what if every building in the US (where technically feasible) had solar panels, and full advantage of wind power was installed while the fossil fuel plants would be used to supply power when alt energy isn't. Minimum production needs of the fossil fuel plants could be calculated such that production of energy is optimized. I would expect that all coal fired and nuclear plants could be closed and many of oil fired plants could be switched to US produced natural gas. The gov't's role is to expedite not fund. For example, in NC Duke energy has a monopoly, what if that monopoly was no longer in existence? Then local solar, and wind, as well as Duke,companies could lease systems to individuals and businesses in essence sell electricity. All providers can share in costs of maintenance of the grid."

    "Finding alternative energy resources is definitely a step in the right direction. Dr. Alfred Crosby knows what he's talking about. If we put actual effort in finding alternative energy resources our future will be looking clean and efficient. Fossil fuels are finite and using wind power, hydro power, solar energy and ocean energy are all renewable ways of getting the energy that we crave and need. Dr. Crosby said ""Alternative sources of energy can become a satisfactory substitute for fossil fuels if we put as much effort and genius in the effort as we did in producing the first atomic bomb. The most satisfactory single alternative would be hydrogen fusion but that quasi-miracle may be beyond our capability. We may discover that wind, solar, biomass, etc., all piled on top of each other, may have to do, but their success may turn out to require an effort that started a generation ago. Essential to any and all success is the realization on our part that we may be able to do anything, which includes fail."

We don’t have to focus on one alternative energy source, but combining all of them, along with some nuclear power plants can, sooner or later, completely replace fossil fuels. If a mere 5% of US electricity were obtained from wind power, it would reduce greenhouse gas emissions equivalent to taking 17,750,000 cars off the road. Also, wind power cost less per kilowatt than coal, oil, and most natural gas-fired generation. With solar energy, the only negative impacts it puts on the environment are a couple toxic chemicals, which can be recycled and disposed of. If we are serious about making the switch, alternative energy sources combined is a winning team."

    ""People keep saying that alternative energy is useless and not safe to use. However, the U.S. renewable energy resources are practically untapped and vast in size. Without any doubt, the energy demand of mankind can be met from the use of renewable resources. Alternative sources can, and will, be a satisfactory substitute for fossil fuels. If we put as much effort and work into making atomic bombs, alternative energy sources can be satisfactory." Each sentence is a different quote from a different source, and each one of them is completely true. Why should we use other forms of power such as uranium and fossil fuels if it is more harmful and more inefficient than the alternative form of these fuels? Even though there is more demand and more need for the uranium and fossil fuels, alternative energy is vast and practically unused. A well thought out plan to a clean energy economy offers more work, more wealth and better health to disadvantaged communities. If 20% of the U.S.'s electricity was obtained from wind power, it would greatly reduce greenhouse gases. This is what I think about the subject at hand. With alternative energy we can save much time and money in the process."

    "Alternative Energy is the best option we have for our resources today. Using Alternative energy allows more jobs to be available. Also, using hydro power, wind power, solar energy, and ocean energy will be more efficient and clean. We can never run out of Alternative Energy because it comes from nature. But "With the right combination of technologies, it is likely that even the use of coal can be phased out, along with nuclear electricity." This should convince everyone to be for Alternative Energy, because overtime we may not have the energy we have now. Using Alternative Energy can help the U.S get out of debt. The cost of fossil fuels is on the rise and our country shouldn't keep paying for something that is hurting us, rather than paying for something that could help our environment. Keeping our country clean is one of the most important factors to me. So I highly recommend our country to switch to Alternative energy because it's overall better than burning fossil fuels to keep our electricity on. Using the natural resources would be a better option for our country because again it's keep our environment clean and using natural resources is priceless."

For the first time in human history, all electricity can be generated by a combination of renewable carbon-free and nuclear-free technologies." -Helen Caldicott, President of the Nuclear Policy Research Institute.

    A clean world can be achievable, but it's going to take longer than what people estimate; fossil fuels will be around for a long time, and because of how "cheap" and "easy to obtain" fossil fuels are, big companies will not switch to them anytime soon. The government will not allow increased drilling for oil; as a way of lowering pollution from drilling; but at the same time, they are not implementing any alternative methods of energy, or... at least, no national method. Allowing for alternative energy production would give more jobs than drilling does, allowing for more jobs, hence, the percentage of unemployment would go down. If 20% of energy was made by windmills; it would be like taking 71 million cars off of the road. The Sun and Oceans will last much longer than fossil fuels. As a wrap up; Alternative energies can replace fossil fuels, just not yet."

Even though are economy is so reliable on the product of fossil fuel that it would be hard to convince everyone to switch."

Fossil fuel is an energy source formed in the Earth's crust from decayed organic material. Everybody understands that oil, gas, coal, and uranium reserves are finite. We are already using other energy sources besides fossil fuels anyways. Hydrogen fuel is made from coal which is another resource that we can use. A fuel cell is an electrochemical engine that converts the chemical energy of a fuel directly to electricity. Almost always the fuel is hydrogen or hydrogen rich gas mixture. The fuel is cell reaction is: hydrogen + oxygen + electricity + water + heat. There is no reason that alternative energy sources can't replace fossil fuels."

    "A major conservational issue in America today is the usage of fossil fuels. Fossil fuels are deposits of carbon stored underground in the Earth's crust composed of fossilized remains of animals and plants that have decayed over millions of years that are slowly being converted to fuel that can be taken out from the Earth millions of years later and be put to use. Common fossil fuels are Petroleum, Coal, and Natural gas. Can these fossil fuels that we use every single day 24/7 be replaced by alternative energies? Yes I believe that fossil fuels can be replaced by alternative energies. Alternative energies aren't harmful to the Earth unlike fossil fuels. We could replace those fossil fuels with things such as solar, wind power, geothermal tides, etc. Solar Power for example has the smallest environmental impacts. There is no air or water pollution. Another question that is asked a lot is will alternative energy development create more jobs? I think that it could because it would give the unemployed people a new opportunity and get the people who work in the harmful fossil fuels into the harmless alternative energy.

    "Without any question, the energy demand of mankind can be satisfied from renewable sources." By Ulf Bossel PhD.

    We can make the economy moe efficient by producing hydrogen. Hydrogen can be produced from sources like fossil fuels, renewable sources such as wind biomass or solar heat powered thermo chemical reactions and solar photolysis or biological methods. Nuclear power is safe for humans, an average person takes in about 300 millirem of exposure per year. The wind's kinet energy could be harnessed by a wind turbine. A wind turbine looks like a tall skinny fan. Wind energy is the ultimate clean energy it takes away the need to import 6,450 barrels of oil."

    "The Nuclear and fossil fuel industries receive welfare from the government in the form of statutory limits on their liability exposure. In other words no matter how many people they kill, by law they are liable only up to a certain amount. Nobody would invest in nuclear without this law; the risks are just too great. So much for so-called "free" markets and keeping government out of our lives. President Carter had solar panels on the White House. Reagan tore them down. Imagine how cheap energy would be now if we had been pursuing alternative energy since Carter instead of subsidizing the nuclear and fossil fuel industries. Remember when the Republicans refused to end the annual subsidy the government gives to Big Oil?"

    "Alternative fuels most certainly can be worked into the vast majority of power sources, its all a matter of the right person taking the initiative. I'm against nuclear power for obvious reasons, and there are plenty of other, safer alternatives. Wind, tide and sun are good examples, tide power could be taken along flood barriers and floating structures, but I would be concerned about the creatures beneath. Fill deserts with sun and wind farms. Cannabis could fully replace oil and timber, and they absorb a MASSIVE amount of CO2. 4 times the amount of yield as trees, the first Model T Ford was made of Hemp almost exclusively. The plastics surpassed the steel of the time, the fuel was more efficient and it was cheap. Biofuel is another option, but this would cause a direct rise in food and gas prices due to the transportation costs. Wind, solar and tide power I believe are the safest alternatives, but Moderation is key in all scenarios. It is time to abandon these age old harmful shortcuts to power and start thinking about the negative effects that are occuring every day. Alternative power increase, less oil drilling and nuclear tampering, and a decrease in consumption is a realistic goal to achieve. Nuclear power should be gone."

My second example and reasoning is the use of hydrogen as a feul source. Over time hydrogen feul would reduce feul costs and it would be much more enviornmentally freindly,giving of no emmisions."The most satisfactory single alternative would be hydrogen fusion but that quasi-miracle may be beyond our capability." My third and final thought of how alternative energy sources could replace fossil fuels is because of how abundant they are. Hydrogen is renewable and all the other resources are are abundant in our planet other than geothermal. One last reasoning is all of the alternative energy sources are enviornmentally "green.""

    "From my research, I think that wind power is the best way to go for renewable energy. "Wind power is an important part of the strategy to combat global warming," says the National Audubon Society. They also state that wind power is the most economically competitive form of renewable energy. If just twenty percent of U.S. electricity would be obtained from wind power, it would reduce greenhouse gas emissions and that is equivalent to taking seventy-one million cars off the road. I also think that more people are safe with wind power because, you don't have to worry about as much fossil fuel burning that could kill wildlife and even humans. In 2007, the U.S. relied on fossil fuels to supply about eighty-five percent of its energy needs, and renewable resources only accounted for seven percent and nuclear power was the remaining eight.
    Just think about how much better the world could be without having to worry about burning so many fossil fuels. Also the cost of wind energy has come down eighty five percent in the last twenty years. In 2002, wind power cost four to six cent per kilowatt-hour. I just think that wind power is better for our future because it's more environmentally friendly."

    "Growing up, there are certain milestones that one looks forward to. Getting ones driver's licenses, graduating and pursuing a career path. But the monopolistic grips on fossil fuels, such as oil, are beginning to threaten those milestones for not only our generation, but generations to come. In order to lessen the dependence on foreign oils, other avenues of obtaining those oils should be examined. One possible way is the construction of a pipeline running from Western Canada to Oklahoma and Texas. Building this line would give us access to the world's second largest deposit of oil. According to the NPRA,"Canada is the largest source of oil imports to the United States. The proposed Keystone XL pipeline expansion would allow the United States to increase those imports from its North American ally by more than 500,000 barrels per day – decreasing our nation's reliance on imported oil from unstable regions of the world". The pipeline would create roughly 122,000 jobs and create 20 billion dollars. The whole nation would see a decline in prices almost everywhere. As the price of gas decline, f all goods, fatting up the wallets of Americans and throwing our economy back on top."

    "To think that we can go on using up our fossil fuels at this rate or at all is ridiculous. I move for the removal of fossil fuel usage immediately. There are plenty of other options to the earth that work a lot better than oil and nuclear companies want us to know. As said by Helen Caldicott, President of the Nuclear Policy Research Institute, in her article titled "Fuel Plan Beset by Fossilised Thinking" "For the first time in human history, all electricity can be generated by a combination of renewable carbon-free and nuclear-free technologies." Yes, oil and nuclear power have had their benefits. But weighing the good with the bad, there are many reasons not to continue using such crude elements. Just like the Vice President of the Institute for Local Self-Reliance, David Morris said "Oil generates only 3 percent of our electricity. Therefore a 100 percent renewable electricity system does little to reduce our oil dependency -- unless that electricity is used to substitute for oil in our transportation system." So in conclusion, yes, I believe that renewable energy can replace fossil fuels as the dominant energy source not just in the country. But in the world."

All off the energy sources I just listed have all been proven to replace the energy the world uses today. I believe something very similar to the same thing as my friend Braden Hickok. For example, according to Arjun Makhijani, PhD, President of the Institute for Energy and Environmental Research, wind energy by itself in 12 Midwestern and Rocky Mountain States equal about 2.5 times the entire electricity production of the United States. This means that wind energy could produce greater results than all of the United States electricity supply by supplying wind energy in just 12 states of the entire U.S. So, the real question is; how much will the economy suffer or stride by the change of energy consumption? Scientists will always be looking to make different solutions to energy consumption for many, many more years."

Alternative energy is to help the problem with pollution. Alternative energy uses solar, wind power, geothermal, tides, and hydroelectric. The US got eighty-five percent of their energy from fossil fuels, only seven percent from alternative energy. Think of how much pollution could be reduced if we replaced fossil fuels with alternative energy. Between 1999 and 2007, drilling permits for oil and gas extraction on US public lands increased more than 361%. There could be a lot of money saved also if we chose to go a different direction with the alternative energy to try and replace oil with ethanol or some other type of alternative. If captured, the solar radiation reaching the earth’s surface in one year could provide us more than 10,000 times the worlds yearly energy needs! There is a huge problem right now with gas prices, if we could replace that with an alternative source than that could definitely decrease the issues with oil. Fossil fuels are more convenient and easier to find but are very harmful to the earth and could effectively be replaced with alternative energy in my opinion."

The production capacity is declining fast, while our demands for fossil fuels continue to soar. With the demand for oil declining, OPEC will want to constrain production. The U.S has 1.6% of the world's oil, but uses 24%. As Alfred W.

My point is I think sometime in the near future we need to start using renewable resources because it is better on the environment than fossil fuels. Plus fossil fuels are not renewable so if we burn it all you then we won't have anything. Renewable resources will keep fossil fuels around longer for many years down the road.

    ""The US has enough potentially recoverable efficiency savings and renewable energy resources - direct solar radiation, indirect solar radiation, wind, geothermal, biomass, small hydro, and wave-tidal energy, to eventually power the entire US economy, essentially indefinitely, without nuclear or coal." This quote proves that alternative energy sources are possible and can eventually replace fossil fuels. I believe we are going in the correct direction as we slowly change our energy use. It's very expensive to produce, and if we mass produce machines to create alternative energy, we will definitely dig ourselves deeper in debt. For example, it takes 450 pounds of corn to make 25 gallons ethanol. 25 gallons of ethanol will not get your car far. 450 pounds of corn WILL take a lot of money and time to grow. Also, waste from nuclear power plants can remain radioactive from days to thousands of years; which is extremely harmful to our environment. But, again, I believe that nuclear energy should not even be an option due to how dangerous it is. In conclusion I do believe that our primary use of energy is successful, but working our way to an alternative use would be a plus."

With using alternative energy it can also help with the environment issues and even help with global warming! It seems silly to use electricity and then shut it off when you can keep it on all the time. Natural gas and fossil fuels are becoming too expensive to use and our country is already in debt and it seem silly not to start using alternate energy when it’s cheaper and more energy efficient. Why not use alternate energy when we can so we can save money and help our country by not going in debt.

    "Can Alternative Energy sources effectively replace fossil fuels?
    Alternative energy sources are capable of effectively replacing the use of fossil fuels. Fossil fuels are widely used to power homes and automobiles. The United States consumes around 317.1 billion gallons of oil a year. Some alternatives to burning fossil fuels are Wind and solar energy. Solar energy powered the first satellite launched into orbit by the US in 1958. Solar panels use heat energy and water to power things that would normally be powered by fossil fuels. The cost of solar energy has decreased 5% every year over the last twenty years. Solar energy is a practical alternative to using fossil fuels because it reduces the country’s dependence on foreign oil. Another alternative to fossil fuels is wind energy. Wind turns a turbine which powers a generator. "As the size of the wind turbine generators has increased, cost per kilowatt hour generated has decreased. Current costs are around 3.5 to 4 cents per kilowatt hour, less expensive than coal, oil, nuclear and most natural gas-fired generation."( The American Geological Institute). Wind energy produces energy effectively and nothing is burned into the atmosphere as a result of wind energy."

      "The sun doesn't always shine on the solar pannels and the wind doesn't always blow, so what do you do when those energies aren't avliable? It is also very expensive to put these other ways of energy up. it takes a lot of land, time and, and money to make this energy possible."

    "Yes in my opinion fossil fuels can be replaced by an alternative resource. Why? Because with the recourses and options we have it should come easy to help our earth and air become cleaner. Stuff like Solar panels or even talks of the liquid fuel process like cars running on water and atmospheric CO2. Using stuff like this won't only help our cleanliness of the earth and air but our economy, because it would force us to quit producing material that we no longer use. "Jet fuel made from water and atmospheric CO2... LFT reactors would not promote nuclear weapons proliferation and could be manufactured like airliners" (Christopher) That money could go to a lot of other things that we need the most at this time. Running on water I feel is a great idea because of earth is 70% water! What much more do you ask for? Like I said earlier when you look at what could change from all different angles, you probably see a whole new life ahead of you, with maybe having more money in your pocket or more time to do stuff than going to the gas station to fill up your car every 2 days. Overall the smartest decision that we as a nation could make is pursuing an alternative power resource."

    "Yes, alternative energy can effectively replace fossil fuels. Arjun Makhijani said "the available wind energy resources in twelve Midwestern and Rocky Mountain States equal to about 2.5 times the entire electricity production of the United States." If we would put solar and wind energy plants in the Midwest, we could effectively get rid of fossil fuels. We can use the sun, the wind, and the natural heat of the earth and sun to run this whole planet. We don't have to rely on coal and other fossil fuels. We need to invest in a diverse energy source such as solar energy and stop using oil and coal. If we stopped using oil and coal it would increase the health of people, on our planet. We have the technology and the resources to make all of this to happen; we just don't put the money and effort to change over to it. In the near future the planet is going to not have as many fossil fuels we will be searching to find new oil mines and coal mines. So if we change over our way of getting energy we could get rid of the problem of the resources running out."

    "In my opinion of course we can. An alternative energy would be indeed a great change in science and technology. There are so many possible alternative energies we could turn to also. Such as using the sun, water, and wind as mechanical energies. We can even burn trash to get energy, not only would that benefit the less use of fossil fuels but cut down on waste on the plane. "There is a study that if we provided a 110 by 100 mile desert with solar panels it would create enough energy to provide the whole nation with energy" said Bob. All of these different alternative fossil fuels will better the earth and us by so much. Just imagine how much a family would save if they used solar panels and lived in a very sunny and open environment. We can benefit from even using vegetable oil too power our vehicles, that would be so much cheaper and even help better the ecosystem, plus it is free! I do not see why not everywhere and every person is funding these and supporting all of these "free" or recyclable energy sources. So yes I believe fully and totally agree that we can replace fossil fuels with these alternative energy sources."

    "Yes, I believe that alternative energy sources can effectively replace fossil fuels. In my opinion there is no harm in trying to use alternative energy. It has been said that is could only take about 10 years to have carbon-free sources. Yes it will take some time for the government to get everything in place to have a successful run at using alternative sources, but I believe that in the end it will all be worth it. In a quote from Al Gore Jr. he states: "We can make an immediate and large strategic investment to put people to work replacing 19th-century energy technologies that depend on dangerous and expensive carbon-based fuels with 21st-century technologies that use fuel that is free forever: the sun, the wind and the natural heat of the earth... What follows is a five-part plan to repower America with a commitment to producing 100% of our electricity from carbon-free sources within 10 years." Facts say that solar energy powered the first satellite launched into orbit by the US in 1958. They also say that if captured the solar radiation reaching the earth's surface in one year could provide more than 10,000X the world's yearly energy needs."

    "We as a whole could save our fossil fuels, gas, and etc. I believe we could do that by using alternative energy sources. Some of those alternative energy sources are hydro power, solar energy, wind power, ocean energy, tidal power, and geothermal energy. Wind energy resources in 12 Midwestern states equal about 2.5 times the electricity production of the U.S. Wind power is rising; in 2007 20,000 megawatts of wind were installed globally. You have enough power to generate 6 million households. Alternative energy sources are way better for the earth. Al Gore says "here's what we can do, we can make an immediate and large strategic investment to put people to work replacing 19th-century energy technologies that depend on dangerous and expensive carbon-based fuels with 21st-century technologies that use fuel that is free forever: the sun, the wind , and the natural heat of the earth." So if you think about it, alternative would be way more efficient and we could save the other sources of energy. Yes, alternative energy sources could effectively replace fossil fuels because it is cleaner and less harmful to the earth."

    "Yes, I think alternative energy sources can effectively replace fossil fuels. A lot of people don't like the wind and solar energy. But I think it would be good for our planet, because we don't have to worry about diseases, cancers and other things. The Green Recovery plan is a prime example- "its proponents would have us believe that pouring taxpayer money into renewable energy like solar energy and wind would let us create an estimated five million new jobs, and also would allow us to end our reliance on imported oil and give us clean air. I think that going to solar energy and wind would give us a better society. And we will also have clean air, to breathe. Solar energy powered the first satellite ever launched from the U.S to orbit. Also the U.S has 1.6% of our world oil, but it uses 24% of the world's oil production. Also waste from nuclear power plants can remain radioactive from days to hundreds or thousands of years.

    "In my opinion alternative energy can effectively replace fossil fuels in more ways than one. Renewable energy is a viable and immediately needed for alternative to fossil fuels that could boost the U.S economy and reduce the reliance on foreign energy sources. What I mean by that is when they say that since we are having a bad economy, we can have the alternative energies that don't need fossil fuels that they can produce the energy that we need in a daily basis throughout the day. Van Jones, president of Green for All said that "Citizens and community members everywhere are seeking smart solutions to our two biggest problems the economic down turn and the ecological collapse. The nation is finally realizing that the solution to these twin crises are linked that is because everything that is good for the environment and practically that is good in the fight against global warming is a job itself." The reasoning behind his quote is we are dealing with more problems dealing with fossil fuels and the economy because when we use all the oil that the US is producing we are constantly borrowing from other countries so we can keep moving"

    "To me taking up 11,000 total square miles of useful wildlife habitat in the desert is an entirely stupid idea for the use of solar panels. You don't consentrate them in a set climate zone, you spread them out so that the deterioration rates of the panels differ in said climate zones, and so that if a cloud comes out the source of power for the entire nation isn't cut off. Now I know the "best" comment "for" solar replacement is hypothetical, but I felt I'd address the idea of solar power plants the way he coined them and introduce my idea: Don't concentrate solar power sources(clouds). You should use them in incraments and in redundent hybrid systems to make most useful. Or you could put a solar pannel on every home and building in the U.S. but think about the cost, not just for the pannels them selves but for the legislation and mobilization of the FED. Also many building projects often utilize solar pannels in the original planes but those are often phased out do to costs.

    "The only problem with alternative energy is, the fact that there is not enough weight behind the turbines of wind towers, and no weight at all on solar cells. Every time you turn on the lights, there is a draw back on the turbine. This means more force is required to turn the turbine. If the city of Los Angeles turned on their lights all at the same time every wind turbine in the country would stop in its tracks(yes even if there is a lot of wind), causing lots of mechanical malfunctions, and the solar cells wouldn't have enough juice. However a steam powered turbine weights about 200 tons. Meaning it has a lot more weight and power, behind it, making it capable of supporting a high population, and demand. At this point in time there is no such solution to replacing Fossil Fuels, we just don't have the technology at this point in time."

    ""Renewable energy sources are essentially a cottage industry. They can help provide some of the clean energy that's needed, but their role is severely limited by the vast amounts of land that they require for large-scale deployment, and their lack of reliability. Solar and wind account for only 2 percent of the nation's electricity. Their roles should increase - but as they grow, we will have to build conventional power plants to back them up." - Nolan E. Hertel, PhD

    My opinion, alternative energy may be able to replace fossil fuels, but it definitely wouldn't be 'effectively'. The reason I say that is, we can produce energy from solar, wind, geothermal, tides and hydroelectric power, but none of those can produce as much energy as fossil fuels can. I do believe that the alternative energy can help provide the clean energy that the environment really needs, but they just tend to take up too much space. Plus, as of right now they need help from an additional source, which are power plants. I also want to add that to make ethanol it takes enough corn that could feed one person for a whole year."

    "Can alternative energy sources effectively replace fossil fuels? Arjun Makhijani, PhD, President of the Institute for Energy and Environmental Research would say yes. He said "With the right combination of technologies, it is likely that even the use of coal can be phased out, along with nuclear electricity." But, there are others are saying that we can never replace fossil fuels. I would say that there is no current technology in the world to day to produce as much energy as fossil fuels can generate as efficiently as we can drill for oil. I say this because In 2008 the US relied on fossil fuels in the form of coal, natural gas, and petroleum to supply 83.5% of its energy needs, down 2.75% from 2004. Renewable energy, such as wind, solar, and biofuels, accounted for 7.4% of US energy needs in 2008, up 1.1% from 2004. It is also not possible to completely phase out fossil fuels with any other current energy that we have today. Solar power is an alternative energy but the space it takes and the cost of using solar energy is not remotely close to the drilling of oil, which is now not very costly or as big of an environmental impact."

If we do that, we can observe the pros and cons to it, and whether it is helping overall or hurting us. Then, if that were the case, we could phase it out and move onto something else.

    ""Although wind, solar, biofuels and nuclear all compete with fossil fuels as sources of primary energy, their contribution to the world's total energy demand is limited because they are more expensive than fossil fuels - and in the case of nuclear, limited by waste and disposal concerns... we recognize the risks of climate change we also conclude that the world will continue to demand oil and gas for a majority of its primary energy" a quote from Exxon Mobile. I personally don’t believe that alternative sources can effectively replace fossil fuels because of three main reasons. One reason is because of the high costs of alternative sources. Another reason why fossil fuels can effectively be replaced is because the fed has attempted to encourage such alternatives for the last thirty plus years with numerous failures and very few successes if any. The last reason why I don't believe fossil fuels can be replaced is because if we were to use crops such as corn it would produce ethanol raises major nutritional and ethical concerns. This would also raise the prices for the foods that contain the crop as well. All in all I don't believe that fossil fuels can be replaced."

      "As I have written on every other post, anti-alternative energy people aren't thinking about it hard enough. Why do we have to completely replace fossil fuels right away? Couldn't we just slowly increase the annual percentages of alternative sources of energy? Why do we have to go all in all at once? Baby steps is what it is all about. If the time came when we actually decided to experiment with using more alternative sources, and the bad ended up outweighing the good, then we could try something else. But in my opinion, we should at least try using more alternative sources, because fossil fuels aren't replenishing any time soon."

    "Four things bother me about nuclear power:

    Insurance companies won't insure it, apparently under any circumstances. In other words, it's simply a bad bet.

    It needs to be monitored and controlled by big corporations and governments, neither of which I trust.

    How will we store the nuclear waste safely where it will be secure for perhaps as long as past human history?

    The only real solution to most environmental problems is control of human population numbers.

    On the pro side, James Lovelock says he'd happily bury a cubic yard of nuclear waste in his back yard and use it for a power supply.

    The animals in the Chernoble (sp) area are perfectly happy to be free of humans. Maybe we should put less value on safety."

    "Alternative energy defined as wind, solar, biomass, geothermal, and wave-capture technologies are all wonderful ideas, but at the moment, that is all they are. Infrastructure must be put in place for such technologies to be made viable. Furthermore, the addition of nuclear to the term "alternative" may push the clean energy movement beyond start up phases. Finally, the answer is no, not right now."

    "Alternative Energy would be a very hard thing to obtain. Most sources are very costly and making them safe and usable for everyday life would be a very hard and costly process. The use of Hydrogen in cars would be a big risk, it may not catch on just like ethanol fuel didn't. It is very flammable and we cant have that on the road incase of accidents."Ethanol is a net energy loss - it takes 70 percent more energy to produce than is obtained from the product itself. Other biomass resources show, at best, very low net energy recovery..." Things economically would have to swing back around because our government is trillions in debt and we can't afford to make any big scientific mistakes. Most alternative energy sources are not cost efficient, even though they may be resourceful, they cant be trusted to give the economy the help it needs as quick as we need it."

      "what is "it"? Pronouns make your statement hard to understand. Also, there will always be people who don't do what is asked, if we focus all our governments resources on making people use alternative energy then enough people will use alternative energy to cripple the fossil fuel industry, however, this use of resources is probably a bad idea."

    ""The wind doesn't always blow and sunlight isn't always striking every solar panel. Renewable energy desperately needs a very big battery, a load leveler. Without some form of energy storage, renewables are physically limited to less than a twenty percent share of the grid. At twenty percent, renewables are more of a headache than a resource for a grid manager. Electricity storage tools are expensive. Very expensive. Too expensive to justify on their own or at societal scale." David B. Barber, MS

    My opinion, No I don't think alternate energy can replace fossil fuels. I say this because alternate energy is more expensive then fossil fuels and they take up a lot more room because of wind mills, solar panels, geothermal, tides, and hydroelectric power. Also, the wind mills killed maybe more than 4,700 birds in a year. And another things is that the wind doesn't always blow, so if the wind doesn't blow then there is no energry saving being produced. Alternate energy only produces 7% of are U.S energy and 85% is fossil fuels. Yeah fossil fuels might be bad for our environment but alternate energy can't completely replace fossil fuels."

    "There are many different types of alternative energies, such as wind power and sunlight. Then again David B. Barber also stated correctly "that the wind doesn't always blow, and the sun doesn't always hit every solar panel." There is no way that alternative energies can effectively replace the uses of fossil fuels. In 2003-2007 85% of the world's energy came from fossil fuels, and only 7% of the world's energy came from alternative energies like solar panels and wind power. Even if all of the corn that is produced in the U.S was turned into ethanol, it would only be able to support about 6 percent of the world's oil consumption. Also fossil fuels are a much cheaper way of creating energy then the alternative sources. Although the idea of energy independence is a pleasing idea, the reality of it happening is impossible. The world today is to relying on fossil fuels."

    ""From 2003-2007, the US relied on fossil fuels in the form of coal, natural gas, and petroleum to supply about 80% of its energy needs and renewable sources for 7% of its needs." I'm Con on whether alternative energy can effectively replace fossil fuels because fossil fuels have run this earth for years. It will take years and lots of money to complete/perfect everything for our country to mainly run on renewable resources. I don't think that our Country is ready for a change this big. It is said that renewable resources are inefficient, expensive, and unreliable. Yes fossil fuels can be expensive but what's new? With fossil fuels we all know what we are dealing with unlike renewable resources. Many people don't know much about them. One of the top ten pros and cons were increased oil drilling. "It is estimated that there is enough oil and natural gas offshore and in non-wilderness and non-park lands in the United States - but currently ruled off-limits for production by the federal government - to fuel 50 million cars and heat nearly 100 million homes for the next 25 years.""

      "I do agree that it will take years to perfect it, and it will also take more money, but we spend alot of money in the government on other things. For example, right now we are paying $3.87 for gas which is completly outrageous. I just think about what if we do "run out" of our natural resources. If the government doesnt plan on it, then we will have no way out when that time comes. It might not happen in our life time, but I would like a better and cleaner future for my grandkids. If the government starts planning now, while we still have the elements available then the world can take an easier transition into alternative energy sources."

    "“We want to be very clear: solar cells, wind turbines, and biomass-for-energy plantations can never replace even a small fraction of the highly reliable, 24-hours-a-day, 365-days-a-year, nuclear, fossil, and hydroelectric power stations. Claims to the contrary are popular, but irresponsible...We live in a hydrocarbon-limited world, generate too much CO2, and major hydropower opportunities have been exhausted worldwide." My opinion of whether we should "can alternative energy sources effectively replace fossil fuels" is no there is nothing that could fully replace the needs that we use with fossil fuels. I think that we should try to use our fossil fuels less than we do now and we should try and spend a little more money in trying to find out where we can get more of it in different places of the world. Facts: "...hydrogen is difficult to store and dangerous to handle..." - Walter Youngquist, PhD, "...the world's total energy demand is limited because they are more expensive than fossil fuels..." - ExxonMobil, "...We will all be forced to consume less energy..."

    ""Several recent bills would either subsidize or mandate alternative fuels and/or vehicles. However, the 30-plus-year history of federal attempts to encourage such alternatives includes numerous failures and few, if any, successes..." I feel like today we just can't fully grasp what it takes to make a change so big. I don't think our country is ready for such change. With the rate we are at now, I don't think it would be smart to try something so permanent. Once we are in a good place and settled down perhaps giving alternative energy a shot could work, but for now I think the fossil fuels are okay. I just don't think our country could survive driving hybrids and using wind energy. Now there is a possibility that fossil fuels could run out and if that were the case alternative energy would be my next choice. Until that time comes I think we should stay the course. The use of corn and other biofuels to solve our energy problem is an ethically, economically, and environmentally unworkable sham. Hydrogen has high cost, poor energetics and scant environmental. The sun's energy is too widely dispersed and the land area required to collect it too vast for solar to become a large-scale power source."

I do believe that renewable energy is a headache because when there is no wind, the wind turbines will not move. So what energy does it produce? Wind power directly kills dozens of bats and birds (also endangered species) each year. Also, they want us to use more natural resources because of the 'lack of oil' did you know Newt Gingrich said that Obama's government won't let us drill in the United States. Also, America is sitting on 1.4-1.7 trillion barrels of oil? That would lower our gas prices significantly. We are too dependent on drilling with other people and having gas at $4 a gallon. If we drill our oil in the United States, we would free ourselves from having to be so dependent on other people."

    "The First Half of the Age of Oil comes to an end, being partly responsible for the current financial and economic crisis facing the world. Oil and gas are set to decline during the Second Half of the Age of Oil to near exhaustion by the end of this Century due to natural depletion. Today, renewable energy, including hydro, accounts for no more than about 12% of the world's energy consumption. It is evident that the demand for it will grow greatly in the years ahead, but it is doubted that it can replace fossil fuels as such. Improved efficiency and changed lifestyles are called for to meet the challenges imposed by Nature. The tensions and challenges of the transition threaten to be serious."
