The Earth receives 174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere. Approximately 30% is reflected back to space while the rest, 122 PW, is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth''s surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet. Most of the world''s popu

Where does solar energy come from?
Please try again later. Solar energy originates from the Sun, a star at the center of our solar system. The Sun emits energy in the form of electromagnetic radiation, including visible light, infrared, and ultraviolet rays. This radiation reaches the Earth and is harnessed through various technologies to generate electricity or heat for human use.
How does solar energy work?
Solar energy is harnessed from the sun's radiation, which is virtually limitless and consistently radiated towards the Earth. This continuous source of energy can be transformed into electricity through photovoltaic cells or used for heating and cooling purposes through solar thermal systems.
When was the first solar power plant built?
Shuman built the world's first solar thermal power station in Maadi, Egypt, between 1912 and 1913. His plant used parabolic troughs to power a 45–52 kilowatts (60–70 hp) engine that pumped more than 22,000 litres (4,800 imp gal; 5,800 US gal) of water per minute from the Nile River to adjacent cotton fields.
When was the first solar engine built?
Shuman then constructed a full-scale steam engine powered by low-pressure water, enabling him to patent the entire solar engine system by 1912. Shuman built the world's first solar thermal power station in Maadi, Egypt, between 1912 and 1913.
How much solar energy can be produced a year?
It was stated that solar energy has a global potential of 1,600 to 49,800 exajoules (4.4 × 10 14 to 1.4 × 10 16 kWh) per year (see table below). Data reflects assumptions of annual clear sky irradiance, annual average sky clearance, and available land area.
Is solar energy a variable or intermittent energy source?
However, on the earth's surface, solar energy is a variable and intermittent energy source. Nevertheless, use of solar energy, especially for electricity generation, has increased significantly in the United States and around the world in the past 30 years.
