Well I have good news for you, we are.
Over 90% of new power generation being built (both domestically and globally) is renewables. We do it for the same reason China and everyone else is: it’s just cheaper now.
That’s the best reason because it’s the one that gets the job done. Renewable energy prices will keep falling while fossil fuel prices rise, widening the gap.
In 25 years there will be little fossil fuel generation left.
