Unless battery prices drastically drop, 2 days of power is 60kwh (quoting earlier figure), even if batteries were $100/kwh, that's $6000 in batteries (or ~$9

Unless battery prices drastically drop, 2 days of power is 60kwh (quoting earlier figure), even if batteries were $100/kwh, that's $6000 in batteries (or ~$9 if you're on grid)
edit: bad math, had $60k
- makomk 6y agoI think you're off by an order of magnitude there? $100/kwh * 60kwh is $6000, not 60 grand.
- nicoburns 6y agoWhat makes you think they won't drop significantly? PV panel costs have dropped by dramtically due to efficiencies of scale, and batteries are only just seeing production begin to ramp up.
- rhodozelia 6y agohow long before I can buy a Tesla for 50% of what one costs now? If the batteries are going to get so cheap we should be seeing some great price drops in electric cars. If not ... why not? And that reason will probably apply to battery energy storage too.
- hn_throwaway_99 6y agoI should have been more explicit in my post. I was talking about car batteries. Tesla cars have batteries in the 60-100 kWh range, and Vehicle-To-Home (V2H) power is becoming a real thing, and I predict over the next few years it could have a large impact on the ability of the grid to use that energy storage to help even out renewable power variability.
