Another easy way to help with this problem is to use EVs. They are essentially large batteries on wheels, and CA has the most (numerically and per capita) in the USA. All you have to do is install chargers where people spend their time during the day (work, shopping, gym, etc) and charge a substantially lower amount than people pay to charge at night in their garage. If it costs 35 cents/kWh at night in the garage, and it costs 5 or 10 cents/kWh in the parking lot at work, many people will choose to NOT charge their car at night, and instead charge it during the day at their work parking lot, or at Ralphs, or at their gym, etc.
You could try steel or aluminum factories, but that would only happen in many years, if ever, due to over the top permitting and environmental regulations that have to be overcome. This podcast that I listened to today while on the elliptical had an example of a factory (a copper smelter in Idaho) that hasn’t started up due to excessive permitting and environmental regulations. Instead a copper mine in Arizona sends their copper to China to be smelted and then ships it back to the USA for use … albeit at a higher price than it would be if smelted in the USA.
