Nearly everyone agrees that the easiest way to kick-start the transition would be to replace coal with solar and wind power for electricity generation. That would require building lots of panels and turbines while regulating coal out of existence. Distributed generation and storage (rooftop solar panels with.
Solar and wind technologies have a drawback: They provide energy intermittently. When they become dominant in our overall energy mix, we will have to.
Doing away with the last 20 percent of our current fossil-fuel consumption is going to take still more time, research, and investment—as well as much more.
This plan features “levels”; the more obvious word choice would have been “stages.” The latter implies a sequence—starting with Stage One, ending with Stage.
