Emeritus Professor of Physics at the University of Connecticut
Not Clearly Pro or Con to the question "Can Alternative Energy Effectively Replace Fossil Fuels?"
"By some definitions, nuclear energy is 'alternative.' By others, it is not. Specifying things directly, I will say that wind, solar, solar/thermal, solar/thermal/electric, biomass, hydro --- all forms of solar combined can not replace coal, oil, and natural gas.
Geothermal energy is essentially limitless, but by and large is way too deep in the ground to be practicable.
Nuclear energy is essentially limitless, and could easily replace fuels used for heating and electricity production. It could not easily replace fuels for transportation.
Now, if you boil that down to one word, is it pro or con?"
Experts Individuals with PhDs, heads of government, members of state or federal legislative bodies, and individuals with graduate degrees and significant post-graduate involvement in alternative energy or fossil fuel issues. [Note: Experts definition varies by site.]
