The Harris Ranch Tesla Supercharger station is an impressive beast. With 98 charging bays, the facility in Coalinga, California, is the largest charging station in the world. But to provide that kind of power takes something solar can’t provide — diesel generators. //

Just as these charging stations find they can’t run without some fossil fuel backup, the retirement of a coal-fired power plant in Kansas is being delayed to accommodate the energy demands of an electric vehicle battery factory that’s under construction.

Blackmon said that these stories illustrate well the lack of thought going into the demands that will be placed on the grid with increasing amounts of electric vehicle adoption.

As those demands pile on, U.S. energy policy pushes to remove coal, nuclear and natural gas from the grid.

Blackmon said he watched all summer as the Texas grid, which operates separately from the rest of the county, nearly collapsed with the incessant heat. //

Musk has also been taken to task for his solar promises. Energy expert Alex Epstein ran a fact check on Musk’s claim that we could power the world with a small area of the Sahara Desert and “some batteries.”

Epstein calculated that enough battery storage to create a reliable grid would cost $590 trillion for the batteries alone. It doesn’t include the cost of all the transmission infrastructure. And the batteries would have to be replaced every decade.
