This isn't guaranteed to be true. Before electrical household appliances were common, we used far more energy at night because indoor lighting was the primary use case for energy. And we are likely to revert to this pattern again if we ever have a mass move toward electric cars which will be charging at night.
- dredmorbius 11y agoTo be fair: EVs (or other high-demand storage-recharge uses) will most likley operate when supply is abundant. Presently with inflexible base-load power generation (coal and nuclear), that's at night. Given nondispatchable opportunistic generation, that's likely to be during daylight hours. Storage is the electrical demand of last resort, along with other very-high-energy uses (e.g., thermal banking, aluminium smelting, etc.).
- Retric 11y agoElectric cars need less energy than you might think. Using Tesla numbers, 230 miles on 60kwh. Average person drives 13,000 miles per year which averages out to 9.3kwh per day. Split that over 12 hours and your looking at ~780watts. Further, if it cost less we would charge cars during the day. PS: Average household uses 31kwh per day. But, offices are really daytime biased.
