While the economic impacts of switching and investing in cleaner energy sources may be rough in the short run, the Superpower of this century will not be defined by who has the most nuclear weapons, but by the country who controls clean energy resources. If we don't begin enforcing stricter regulations to promote cheap clean energy, I fear the free market will cling to fossil fuels till the very last drop is gone before real investment into the clean energy market begins. If China beats us to green energies, we might lose our footing forever as the most powerful country on Earth, it seems they already have us (metaphorically) by the balls thanks to the free market.
