> The U.S. installed 5.7 gigawatts of solar PV capacity in Q2 2021 to reach 108.7 gigawatts of total installed capacity, enough to power 18.9 million American homes.[1]
> EIA expects that most large-scale battery energy storage systems to come online over the next three years will be built at power plants that also produce electricity from solar photovoltaics, a change in trend from recent years.[2]

- silexia 5y agoSolar only works during the day. We have no battery technology, even remotely close to being able to store the power needed when the sun isn't shining. Houses are not all that big of energy, only using 1/3 of what the US has. The US as a whole needs 3.8 trillion kilowatt hours a year. https://www.eia.gov/energyexplained/electricity/use-of-electricity.php https://www.eia.gov/energyexplained/electricity/use-of-elect...
