Have you heard of a guy named Mark Jacobson? He’s the trendy Stanford professor who has written a couple of big pieces claiming that having the United States get 100% of its energy from nothing but wind, water and solar power by 2050 is no problem at all.
[W]e point out that this work used invalid modeling tools, contained modeling errors, and made implausible and inadequately supported assumptions. Policy makers should treat with caution any visions of a rapid, reliable, and low-cost transition to entire energy systems that relies almost exclusively on wind, solar, and hydroelectric power.
Ouch! But actually, those are the polite words in the piece. For example, what are some of those “inadequately supported assumptions” to be found in Jacobson? Here’s one that I particularly enjoy:
The system in [Jacobson’s piece linked above] assumes the availability of multiweek energy storage systems that are not yet proven at scale and deploys them at a capacity twice that of the entire United States’ generating and storage capacity today.
