    "Alternative energy is not limited to wind, solar, wave etc. but consider the likely probability that there are a great number of wonderful discoveries, technologies, and inventions that are suppressed by the relatively few that have an interest to keep those highly efficient technologies in the dark for the sake of continued profit....or better yet power. There are people in this world who do not wish to allow a sort of leveling of the playing field so to speak. Look up Dr. Steven Greer, Truth Embargo, Stephen Bassett."

    Is it because they weren't Americans that we don't care about this technology?

    I think that it could be used for lots of things here such as, generating electricity, trains, small automobiles and motorcycles."

    "This is a major topic and a major decision towards the near future. At this moment of time, fossil fuels cannot be fully replaced by alternate energy. Although alternate energy use is growing, we don't have the technology to have this fully replace fossil fuels. I know that fossil fuel use isn't helping the environment, but we don't have a way to replace fossil fuels with alternate energy at the moment."

    "Yes alternative energy can replace fossil fuels. Sooner or later fossil fuels will run out. Science shows that fossil fuels cost over 3 million dollars more than alternative fuels do. Alternative is cheaper and more efficient. There is also many different alternative energy supplies. We can use different ones for different places. Also alternative energy doesn't pollute the air. Fossil fuels do. Fossil fuels are nonrenewable and alternative energy is renewable. Alternative energy does have some problems with it but it has way more benefits."

    "Solar energy, for now, is infinite. Solar panels don't have to take up new space, they can replace current space. Such as having solar panel roofs, solar panels on the backs of stop signs, etc. We are killing the planet. We can't go back now. We can't restore her to her previous glory. But we can stop further destruction by protecting the environment, and all living things here on Mother Earth."

    "I'm pro because of the damage that fossil fuels do to the environment. It would cost us more money in the long run to repair damage done to the environment by fossil fuels in the future then if we switch now we can halt the damage fossil fuels do to the environment. Climate change disproportionately effects all of us. It will effect the lives of people in LEDC's more so then in MEDC's yet the MEDC's contribute more to global warming then LEDC's. Alternative energy sources per kwhr are actually cheaper then fossil fuels. It becomes a no-brainer to switch. The problem is that power and money that the fossil fuel industry has in the political and private realm which makes it harder for the general public to make the change especially in the U.S. We should be completely fossil fuel free by 2050. The best alternative energy sources to replace fossil fuels are solar, nuclear and geothermal (in certain places). The other thing is as a country/world we should reduce our fossil fuel/energy intake. We waste a lot of the energy that we do use and if we were more efficient especially in MEDC's with our energy use, then alternative energy can replace fossil fuels."

    "Yes-According to ethanol activist and scientist David Blume (2007) wrote in "Alcohol Can Be A Gas". He documents how any biomass can be processed into alcohol( ethanol) to supply almost all fuels used in all scenarios. He also responded to critics that have tried to use energy balance calculations that based their analysis ofn faulty assumptions and assertions. Blume says that corn is only one possibility for biomass. The most productive source of biomass is hemp. Fortunately , hemp can be grown on rough sloping lands as well as flat ground used to grow corn. This opens up many growing areas that don't compete with food crops."

    "If you include Nuclear Power in Alternate Energy (since it is a Green Energy Source, especially with Thorium), Absolutely. It produces no CO2 (as a result of energy production), it produces much more energy that coal or oil can even dream of producing, it produces less waste than both, and modern techniques are safer than fossil fuels and most other forms of green energy, no matter what the "No Nuke" crowd likes to believe because a few Old, Outdated 20th century reactors overloaded (resultiing in few if any actual deaths)

    If not, than still Yes, it will just take longer since there are still some hurdles to overcome, but they can amd eventually will be overcome."

    "I am an electrical engineer who has done some power resource planning. An important consideration is that we are getting better at constructing buildings and other systems that are more energy efficient. LED lighting is a good example. Solar power is a peaking resource. It is slowly becoming more of a part of new building design, and as a peaking resource it can reduce the use of older fossil plants that generally are used as peaking resources. Solar can help existing base load plants operate at a more stable output, optimizing maintenance. Wind is a unique resource in that its output can vary and thus needs supplementation by predictable resources to maintain system stability. I agree with engineering papers that point out wind has a role to play but cannot become too great a part of the resource mix or transmission system stability could experience chronic problems. We need to determine what the planet and especially our coastal living spaces can tolerate in terms of sea level rise and adjust the number of fossil burning plants our ecology can sustain without going unstable. People need to consider the externalities of burning fossil fuels when pointing out the costs of alternative energy."

They provide 2 basic needs in one project, are used underground where they don't take up so much natural wildlife space like dams do, and they work 24/7 unlike solar panels and wind turbines."

    "It can because it can preserve nature and can be used many times. It is more natural and it is considered healthier for nature. We could do things the natural way again and not need to worry about this anymore. We can convince the entire world to do this if we convince their leaders. If they do not have leaders, then we can make them because we have almost the most control. Almost, as I had said before. It will be easy to convince the leaders and we could all live longer that way and prevent any more types of extinction. I highly doubt that we can prevent all of it, but we can be able to at least try our best after all that we have done to nature. And it should really make at least some type of positive effect. So that is why I say yes!"

    "Fossil fuels will run out. In fact, the fossil fuel consumption rate (the rate in which fossil fuels are used) is greater than the fossil fuel production rate (the rate in which fossil fuels are made) which means fossil fuels will run out very soon. (renewable) Alternative energies help the environment and the economy, so why not use these. Although it would cost a lot to switch from fossil fuels to alternative energies, it is just like switching the main power line from fossil fuel power station A to alternative energy power station B. Climate change would still go on even after we eliminate fossil fuels, but it would slow down. Eliminating and cutting out fossil fuels and putting in alternative energies would create lots more jobs too. So, what are you waiting for, lets start fossil fuel cutout phase one now!!!"

    "Yes. Clean Alternative Energy can effectively replace fossil fuels. This however is only if the battery systems by Tesla are implemented. Large scale power plants use massive turbines to regulate the amount of power in the system. This means if the plant goes offline, there will still be power from the massive turbines. This is how they regulate power. With alternative energy there are no turbines. This means that in order to smooth the flow of energy one would have to use a water differential system or large batteries."

But we can do it." you heard it from an expert not a 15 year old boy soon to be an expert.(school wise he is an expert but the kid can think better than the experts fixed mind set)Michael Klare, PhD, Professor of Peace and World Security Studies at Hampshire Collegesaid "Nevertheless, renewables are likely to replace fossil fuels as the dominant source of electrical power well before mid-century as well as make giant strides in other areas such as transportation.""

Somethings will never change until billions of year from now, the wind will blow, the world will always have a molten ball in the center of it, and the sun will always rise the next day. None of those take million of years of compression to make into a substance that we can use for electricity."

Pharmaceuticals, critical materials, the construction of tooling, scientific equipment,etc. Global warming is happening, anything we can do to slow it while we prepare for it is simply prudent.

Fusion power involves the very same process stars use to produce immense amounts of heat and light. Hydrogen is turned into plasma, which is then turned to helium. This process releases HUGE amounts of energy and is not too far from our reach. One of the things limiting fusion power right now is the lack of research being done in that field. I believe that alternative energy can effectively replace fossil fuels, but just not the current forms of alternative energy we have at our disposal today. We still have a lot to do before we can harness fusion power, but with Hydrogen being the most abundant element in the universe, this is a limitless power source."

    "I fully support alternative energy but until the technology used can become more efficient, fossil fuels remain as the leading source of energy. Many claim that they will eventually run out, but by that time, alternative energy may very well have replaced most of the energy used in the world. This subject is about whether alternative energy can EFFECTIVELY replace fossil fuels in our current society, not about the future. While, again, I do support renewable energy, it remains to be expensive and a small source of power used globally. Hopefully someday, when human technology has advanced, we can use renewable energy as our main input."

    "For starters, people on here are being rather bias and choosing their up/down votes based off of whether they agree with it or not.
    Secondly, renewable resources are renewable because more are being made than used, we can only cut down so many trees before they're no longer considered renewable. (Trees were an example)
    Thirdly, the switch would greatly increase our pollution for the few decades, or more realistically, generations, that we are trying to build the stuff to use solar power, or wind power, or biomass, or whatever else we want to use.
    In conclusion, we don't have a good way to switch, or at least not yet. And hopefully, that changes before we actually need to switch over"

      "1st, I'll agree partially - ethanol from corn is clearly a waste of corn, and is nothing more than a stupid stimulus program for a pointless industry; effectively converting 1 unit of coal energy into maybe 1.1 of gasoline while consuming food.

      But 80% of petroleum is burned, only 20% is used in "product", and thats not even counting coal, which is ~all burned, to make ~40% of our electricity.

      And more plastic is used in toothbrushes than in wind turbines, youre fussing about a vanishingly small percent of consumption - for which the products can make decades of free power. The problem is the millions of tons of (sh)it that ends up in the pacific gyres, followed by millions more made from petroleum and natural gas.

      Nevermind that steel (given your ore comment) is 88% recycled. If everything were recycled like that, we could save the planet..

    "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.

    "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. I know you people will rag on me for not mentioning batteries, but hear this: Current batteries are too inneficient to power entire cities if a storm rolls on by (Think MGW).

Bradley Jr., Founder and chairman of the institution for energy research, says ""Environmentalists support a major phase-down of fossil fuels (with the near-term exception of natural gas) and substitution of favored 'nonpolluting' energies to conserve depletable resources and protect the environment. Yet energy megatrends contradict those concerns. Fossil-fuel resources are becoming more abundant, not scarcer, and promise to continue expanding as technology improves, world markets liberalize, and investment capital expands....", and Nolan E Hertel, a professor of Nuclear and radiological engineering at the Gorgia Institute of Technology, said "Renewable energy sources 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.

    "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."

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."

    ""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 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."

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."

    "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."

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.

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."

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."

    "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."

    "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."

    "no as said by Donald trump, oil is a proven clean energy source. there is no pollution caused by oil made in America. you know who is responsible for the pollution and causes of bad oil, MEXICANS!!! vote for trump 2016."

      "that makes no sense and also by "driving big gas guzzling trucks" you are contributing to air pollution, which anyone with any common sense AT ALL knows is caused by humans. i think you're going to be one of the first ones to die with lung cancer."

    "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."

    "No it cannot. Alternative energy is run by tax payer dollars and cannot sustain itself. Look at Solyndra. The government gave it $528 million and it went bankrupt. This is why it will never replace fossil fuels."

      "The sun will stop shining at some point in the deep, deep future, and then eventually the rivers will stop flowing, the winds will stop blowing, the core of the earth will stop glowing, and the moon will slow down and crash into the earth, stopping the tides. What do we do then?"

      "Unless you can make a wonderful prediction that the sun will stop shinning, winds will stop blowing, and water will stop flowing then your comment has no ground work. Solar power on the other hand in way to expensive at this time, wind and tidal energy is much cheaper then coal and petroleum and guess what they wont run out until the sun stops shining"
