Liberal politicians like Barack Obama, Bernie Sanders, Joe Biden, and John Kerry tell us global warming is the greatest threat to our national security and future generations, requiring the transformation of our economy to expensive and unreliable wind and solar power. If the left is sincere about this assertion, then they should support all energy sources that reduce carbon dioxide emissions. This presents conservatives an excellent opportunity to call the left’s bluff or make them put their money where their collective mouth is.
Wind and solar, after all, are not the only power sources that produce little or no carbon dioxide emissions. Natural gas power emits only half as much carbon dioxide as coal power, and hydro power and nuclear power emit no carbon dioxide emissions at all. Natural gas and nuclear power are available on-demand, unlike wind and solar power that are extremely limited on cloudy days, low-wind days, and at night. Hydro power is not quite an on-demand power source, but it is much more reliable and predictable than wind and solar. Because wind and solar require conventional power backup, hydro and nuclear power actually reduce carbon dioxide emissions even more effectively than wind and solar, and natural gas emissions become comparatively smaller relative to wind and solar.
Conservatives have long championed natural gas, hydro, and nuclear power because of their relative affordability. Natural gas power and hydroelectric power are cost-comparative with coal power. Nuclear power is about 50 percent more expensive, but new technologies and more common-sense government regulation offer the promise of significant reductions in future costs. Even without any such future cost reductions, nuclear power remains substantially more affordable than wind and solar.
