Solar power generation, 2025
Electricity generation from solar, measured in terawatt-hours.
The world currently has a cumulative solar energy capacity of 850.2 GW (gigawatts). 4.4% of our global energy comes from solar power. China generates more solar energy than any other country, with a current capacity of 308.5 GW. The US relies on solar for 3.9% of its energy, although this share is increasing rapidly every year.
While the contribution of solar energy to global electricity production remains generally low at 3.6%, it has firmly established itself among other renewable energy technologies, comprising nearly 31% of the total installed renewable energy capacity in 2022 (IRENA, 2023).
Over 7.3 million homes in the U.S. are using solar power. The U.S. has enough renewable energy resources to produce 100 times its yearly electricity needs. Every day, the Earth gets about 174 petawatts of solar energy. By 2050, solar energy is expected to provide half (50%) of the world's electricity.
3,975,096 people are employed in the solar industry worldwide, and 263,883 of these are in the United States. The solar energy industry created more new jobs in the US than any other energy subsector last year. It would take around 18.5 billion solar panels to produce enough energy to power the entire US. What is the capacity of solar energy?

The present review study, through a detailed and systematic literature survey, summarizes the world solar energy status along with the published solar energy potential assessment articles for
Solar power is an energy source that has been around for quite some time. It''s only recently, however, that people have begun to truly understand the potential of this energy source and
In our STEO forecast, utility-scale solar is the fastest-growing source of electricity generation in the United States, increasing from 290 BkWh in 2025 to 424 BkWh by 2027. Almost 70
The cumulative global solar generation increased from just 32 TWh in 2010 to 1250 TWh in 2022. Solar generation has grown over 20% annually since 2020 increasing from 180 TWh to 245
Solar PV and wind will account for 95% of global renewable expansion, benefiting from lower generation costs than both fossil and non‑fossil fuel alternatives. Over the coming five years,
In the last few years, solar energy has been the main driver for renewable energy growth worldwide. In 2024, solar photovoltaic capacity additions surpassed 600 gigawatts, accounting for
Solar Energy Statistics stated that over the past 10 years, the price of solar panels has dropped by more than 60%. The cost of solar battery storage has decreased by 72% since 2015.
Renewable energy sources include wind power, solar power (thermal, photovoltaic and concentrated), hydro power, tidal power, geothermal energy, ambient heat captured by heat pumps, biofuels and
