Electricity generation. In 2023, net generation of electricity from utility-scale generators in the United States was about 4,178 billion kilowatthours (kWh) (or about 4.18 trillion kWh). EIA estimates that an additional 73.62 billion kWh (or about 0.07 trillion kWh) were generated with small-scale solar photovoltaic (PV) systems.
Solar energy comes from the limitless power source that is the sun. It is a clean, inexpensive, renewable resource that can be harnessed virtually everywhere. Any point where sunlight hits the Earth''s surface has the potential to generate solar power. Unlike fossil fuels, solar power is renewable. Solar power is renewable by nature.
