Solar energy is the radiant energy from the Sun's light and heat, which can be harnessed using a range of technologies such as solar 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…

Solar thermal energy (STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in industry, and in the residential and commercial sectors. Solar thermal collectors are classified by the United States Energy Information Administration as low-, medium-, or high-temperature…

Solar Energy Generating Systems (SEGS) is a concentrated solar power plant in California, United States. With the combined capacity from three separate locations at 354 megawatt (MW), it was for thirty years the world's largest solar thermal energy generating facility, until the commissioning of the even larger…

Canadian Solar Inc. (NASDAQ: CSIQ) is a global renewable energy company.

A bifacial solar cell (BSC) is a photovoltaic solar cell that can produce electrical energy from both front and rear side. In contrast, monofacial solar cells produce electrical energy only when photons are incident on their front side.

The American multinational retail chain Walmart has received criticism from parties such as labor unions and small town advocates for its policies and business practices. Criticisms include charges of racial and gender discrimination, foreign product sourcing, anticompetitive practices, treatment of product…

The use of solar energy began in Israel in the 1950s with the development by Levi Yissar of a solar water heater to address the energy shortages that plagued the new country. By 1967 around 5% of water of households were solar heated and 50,000 solar heaters had been sold.

The Renewable Energy Corporation (REC) is a solar power company with headquarters in Singapore. REC produces silicon materials for photovoltaics (PV) applications and multicrystalline wafers, as well as solar cells and modules.

China is the largest market in the world for both photovoltaics (PV) and solar thermal energy. Its PV capacity crossed 1,000 gigawatts (one terawatt, 1 TW) in May 2025.

A Zero-Energy Building (ZEB), also known as a Net Zero-Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site or in other definitions by renewable energy sources…
