Then how is it you think the only thing we can do is replace col with nukes?
And, by not producing power when it isn't needed, throttling the fuel consumption.
On marginal land.
And Florida, Texas, Arizona, New Mexico, Nevada, Utah, California, the Sahara, Greece, Italy, France, Lebanon, the Middle east, Australia, there's plenty of suitable land out there available. The sun delivers 7000 times more energy than we consume globally. We only need to use a fraction of available land to provide huge amounts of power. Not with PV panels, they are not as efficient as solar thermal.
And China is eating our lunch on these renewable technologies. All while we have waited for China to commit, before we pass our own legislation, China has been producing more and more of the World's renewable energy infrastructure.
