CA will be even more expensive

The average amount of power used by gasoline cars in CA today is ~74,000 MW per hour. 

The current electrical generating capacity in CA is ~80,000 MW. 

California plans to ban gasoline powered cars.

I guess that means they think they will switch to electric vehicles powered by wind and solar. If the build fossil fuel plants there is really no benefit to global warming. And it seems impossible that they would go nuclear. 

If this is the case there will be a dramatic cost to do this including:

1. The cost of doubling their power generating capacity. 

2. The cost of energy storage. The sun doesn’t shine at night and the wind often dies at night, when cars will need to recharged. 

3. The cost of having to install all of the infrastructure to transport additional electricity. 

4. The cost to build all of the charging stations. 

5. The additional cost electric vehicles versus gasoline vehicles.

6. The external costs associated with manufacturing and disposing  of batteries. 

How smart is this?
