In contrast, the net additions of nuclear capacity and coal capacity and the orders behind those keep fading because they cost too much and they have too much financial risk.

We're often told though that only coal and nuclear plants can keep the lights on, because they're 24/7, whereas wind and solar power are variable, and hence supposedly unreliable.

Traditionally utilities build a lot of giant coal and nuclear plants and a bunch of big gas plants and maybe a little bit of efficiency renewables.

Now combine the electricity and oil revolutions, both driven by modern efficiency, and you get the really big story: reinventing fire, where business enabled and sped by smart policies in mindful markets can lead the United States completely off oil and coal by 2050, saving 5 trillion dollars, growing the economy 2.6-fold, strengthening out national security, oh, and by the way, by getting rid of the oil and coal, reducing the fossil carbon emissions by 82 to 86 percent.

It turns out that natural gas is displacing our dependence on coal, which emits far more carbon dioxide.

When the Industrial Revolution started, the amount of carbon sitting underneath Britain in the form of coal was as big as the amount of carbon sitting under Saudi Arabia in the form of oil.

Coal and natural gas are cheaper than solar and wind, and petroleum is cheaper than biofuels.
