Solar energy is the radiation from the Sun capable of producing heat, causing chemical reactions, or generating electricity. The total amount of solar energy received on Earth is vastly more than the world's current and anticipated energy requirements. If suitably harnessed, solar energy has the potential to satisfy all future energy needs.
• Nov. 18, 2024, 1:40 PM ET (BBC) solar power, form of renewable energy generated by the conversion of solar energy (namely sunlight) and artificial light into electricity. In the 21st century, as countries race to cut greenhouse gas emissions to curb the unfolding climate crisis, the transition to renewable energies has become a critical strategy.
Solar energy - Electricity Generation: Solar radiation may be converted directly into solar power (electricity) by solar cells, or photovoltaic cells. In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors.
Solar energy is commonly used for solar water heaters and house heating. The heat from solar ponds enables the production of chemicals, food, textiles, warm greenhouses, swimming pools, and livestock buildings. Cooking and providing a power source for electronic devices can also be achieved by using solar energy. How is solar energy collected?
There are several ways to turn sunlight into usable energy, but almost all solar energy today comes from “solar photovoltaics (PV).” Solar PV relies on a natural property of “semiconductor” materials like silicon, which can absorb the energy from sunlight and turn it into electric current.
An electric grid with lots of solar power must pair it with other technologies for reliability: energy sources like hydropower that can be powered up and down at will, energy storage (like batteries) to save up solar energy when it’s plentiful, and/or long-distance transmission to move electricity from the sunniest spots to where it’s needed.
