Energy captured from sunlight, either directly as electricity in photovoltaic cells or as heat in solar thermal systems. From the first practical silicon solar cell in 1954, photovoltaics fell in cost by orders of magnitude to become, in the 2020s, the cheapest source of new electricity in much of the world and the fastest-growing major energy source.

Rooftop solar photovoltaics is the dominant real-world use case for net metering programs.
Space-based solar power is a variant of solar power generation, collecting sunlight via orbital photovoltaic or thermal collectors and beaming the energy to Earth rather than collecting it terrestrially.
