Exactly. The solar energy that can be captured throughout the year using not much more than the roof area of a single-family home would be enough to cover its entire annual energy needs, both for electricity and heating. The problem is that you need to store about 30,000 kWh of energy over a period of several months. That’s on the order of 400 Tesla Model 3 batteries worth of storage. Not only is it prohibitively expensive. Those batteries would also be missing in production of electric vehicles.
- ClumsyPilot 4y agoThe peoblem is your consumption of energy happens through you consuming goods, and energy was used to produce them, so its industrial.
- leobg 4y agoThat’s a good point. But for industry, it could work the same. Solar plus seasonal storage. Probably not important for countries like the US, that don’t depend on imports of oil and gas. But for those countries to do, being able to utilize the energy that comes down from the sky for free could be a game changer both in terms of economics and foreign affairs.
