> I have done a fair amount of noodling I did the same noodling years ago, when battery prices were "only" dropping at 8% per year. My conclusion was in your decade or two, it's possible energy production and storage will be driven by solar and EV's in the suburbs respectively. I don't see how that won't happen, to be honest. The costs they talk about in the article, like $70/MWH, is the wholesale price. The customer pays about 3 times that. If batteries and solar look good at $70/MWH, they look like gold raining from the sky when you are paying $240/MWH. Right now where I live, you can buy a dedicated house batteries. They cost as little under $1000/kWh installed. Or you can buy an EV which works out at $600/kWh for the battery, and you get the rest of the car for free :D. If the current trajectory of battery prices continues, the fate of the car industry is sealed. It's all over bar the shouting. When means everyone is going to have a positively gigantic parked in the garage regardless of what the insurance companies you are wringing your hands over think of it. And yes solar panels on the roof are a hassle, but you can justify a lot of hassles when your power costs 300% more if you don't have them on the roof.
