How would doubling / tripling help you when there is little wind and clouds for a few days?
- trhway 5y agoClouds in Alger while no wind in Atlantic? Total, so not even 0.5 GW generated among them for days so the storage gets depleted too.
- powerbroker 5y agoGet the Electric Vehicles to 'stock up' on kWh prior to the cloudy/no-wind period. And then induce them not to charge during the cloudy/no-wind period with a 'renewable hiatus' premium, of, say, 50-100% of the normal price of a kWh.
- Krssst 5y agoA Tesla model S seems to be able to store 100kWh. France seems to have ~30M cars. So, 100e330e63600~=1e16 J storage assuming all those cars switch to being Tesla S, and are somehow kept unused. France consumed 529e6/1.17 MHw according to https://www.worldometers.info/electricity/france-electricity/ https://www.worldometers.info/electricity/france-electricity... (in 2016). So, average consumption is 529e12/1.17*3600/365/86400 ~= 50GW. 1e16J / 50GW is 200,000 seconds or 2.3 days. So, not completely unreasonable, but it still seems on the low side (only two days), and I am not sure what the impact would be on car batteries to be continuously charged/discharged. This also assumes cars are left at home to serve the grid. This also assumes electricity consumption does not increase, which seems unlikely (since transportation and heating must switch to electricity at some point).
