That analysis assumes that renewables can displace coal… they can’t. They can only displace gas, which can be ramped up and down quickly (~20 min) when the sun and wind come and go. Coal plants take many hours to ramp up and down. So none of the analysis makes sense.
- Michael Shellenberger, founder of The Breakthrough Institute, commenting on a recent analysis that found that renewable energy is responsible for over 50 percent of recent reductions in U.S. carbon emissions.
I’ve been pondering whether to weigh in on all the noise resulting from two recent studies about the failure of cap and trade policy a few years back. David Roberts nicely sums up his thoughts on the matter here, and, as usual, I largely agree with him.
First, full disclosure: I was there. As director of communications at ClimateWorks during this period, I have a pretty good sense of what went down. But rather than offering my views on what’s in these studies and joining in the mano-a-mano on he said/she said/who’s wrong/who’s right etc., I’d like to draw a sharp focus to what I think is the Real Big Issue that’s NOT being discussed.
