READ MORESolar PV accounted for 4.5% of total global electricity generation, and it remains the third largest renewable electricity technology behind hydropower and wind. China was
READ MORESolar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage. Below, you can find resources and information on the basics of solar radiation, photovoltaic and
READ MOREFrom the late 1800s until today, fossil fuels—coal, petroleum, and natural gas—have been the primary sources of energy. Hydropower and wood were the most used renewable energy resources until the 1990s. Since then, U.S. energy consumption from biofuels, geothermal energy, solar energy, and wind energy have increased.
READ MOREIn 2025, renewables surpass coal to become the largest source of electricity generation. Wind and solar PV each surpass nuclear electricity generation in 2025 and 2026
READ MORESolar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy (including solar water heating), and solar architecture. It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar
READ MORE3 · In the 21st century solar energy has become increasingly attractive as a renewable energy source because of its inexhaustible supply and its nonpolluting character, in stark contrast to the finite fossil
READ MOREThe term "renewable" encompasses a wide diversity of energy resources with varying economics, technologies, end uses, scales, environmental impacts, availability, and depletability. For example, fully "renewable" resources are not depleted by human use, whereas "semi-renewable" resources must be properly managed to ensure long-term
READ MOREIn 2028, renewable energy sources account for 42% of global electricity generation, with the wind and solar PV share making up 25%. In 2028, hydropower remains the largest
READ MOREFor non-bioenergy renewable sources, this share is as high as 80% with the remainder in the form of heat produced in solar thermal and geothermal installations. Wind and solar
READ MOREIncreasing the supply of renewable energy would allow us to replace carbon-intensive energy sources and significantly reduce US global warming emissions. For example, a 2009 UCS analysis found that a 25 percent by 2025 national renewable electricity standard would lower power plant CO2 emissions 277 million metric tons
