Power generation & transmission
For America to be able to run on renewable power by 2050, we would need enormous amounts of renewable power to be delivered throughout the day and night. The consumption of electricity would change dramatically as the current peak hours would be displaced by peak hours at night when every household that has electric car is charging its vehicles.
The demand for electricity is expected to double to 2400 GW, 70% of which would be supplied by solar, wind, and geothermal power. In order to prevent outages, battery backup will be needed as solar and wind power are intermittent. Since the United States would not have solar power generation at night, we would primarily rely on wind power, which is only seasonal. This leads a tremendous reliance on battery storage which is expensive and would require investment in the tens of trillions of dollars.
Convalt Energy is currently developing a solution to provide 100% renewable power by 2040.
