See here. This is a report from the Powerline blog about testimony in Congress by Robert Bryce, an energy expert. It contains his summary of his testimony, and here are my highlights of that summary:
(1) "In 1990, the California Air Resources Board mandated 10% of car sales be zero-emission vehicles by 2003. Today, 31 years later, only about 6% of the cars in California have an electric plug.” Let me add that some people seem to think that we can mandate innovation. We cannot. It happens when it happens. We can throw money into research in an area, and maybe we will get some great results. But maybe we won’t. Thomas Edison spent a lot of money trying to deal with low-grade iron ore by crushing rocks and then using magnets to separate the iron ore from the waste. I read this in a biography of him a couple decades ago, so my memory may not be accurate, but he ran into problem after problem trying to do this, and he never got it to work.
(2) Right now electric vehicles are for the rich, yet others will have to pay (via their taxes) for the subsidies that are used to make them viable. There will need to be upgrades in the electrical grid, and the poor will help pay for these with much higher electric bills, even though they may never own an electric vehicle themselves.
(3) Right now, California is facing lots of blackouts, so it is very far from having the electrical capacity to deal with the transition to a large number of electric vehicles.
(4) There are supply-chain issues with manufacturing them. We will require 9 times the current cobalt production to have half of our vehicles be electric vehicles.
All the talk about how everyone will be driving an EV by 2030 seems wildly unlikely.
