One of these days someone will produce a genuine economic study of the cost of electric storage. Even under the most ideal circumstances, batteries are not free because of manufacturing, transportation, maintenance, set up and disposal costs. Manufacturing costs, even if the basic materials are cheap and plentiful they are not free and there are theoretical limits on storage efficiency.
Check out “The Manhattan Contrarian”. He has done the economic modelling for battery storage. For NY state alone the costs for battery storage would be in the trillions and that’s if the raw materials were available (spoiler, they are not).
The only answer is nuclear power. Thorium based molten salt reactors.
To think we can store power in batteries on the scale that is needed is ridiculous.
The trouble is the left doesn’t want to solve problems, but rather to use them as controllers.
Problems as power tools, as it were.
Going Green required THREE power plants whereas only ONE would do in the good old days.
1. Plant #1 - solar cells or wind turbines
2. Plant #2 - energy storage to store power when sun doesn’t shine and wind doesn’t blow
3. Plant #3 - conventional fossil fuel plant to provide power when there isn’t enough storage capacity (backup) or energy storage runs dry
How brilliant is that? Spend three times more capital to get the same net output! But “green” trumps all.
