Solar 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 depending on how they capture and distribute sol

Why did renewables become so cheap so fast?

A short history of solar: From outer space to the cheapest source of energy on earth. During the 1960s the main application of solar remained in satellites. But the virtuous cycle was set in motion and this meant that slowly, but steadily, the price of solar modules declined. With falling prices the technology came down from space to our planet.

History of Solar Energy: Understanding Its Evolution and Impact

In 1883, American inventor Charles Fritts coated selenium with a thin layer of gold to form the first functional solar cell, harnessing sunlight to generate electricity. Despite the low conversion

A Brief History of Solar Energy (2024)

Though energy prices decreased quickly under Reagan''s presidency, this came at the cost of research and development of domestic energy sources like wind and solar. During Reagan''s presidency and after, many oil companies quickly offloaded their investments in developing solar energy: 12, 13. In 1984, Exxon sold the Solar Power Corp. to Solarex

Solar power | Definition, Electricity, Renewable Energy, Pros and

Solar power is a form of energy conversion in which sunlight is used to generate electricity. Virtually nonpolluting and abundantly available, solar power stands in stark contrast to the combustion of fossil fuel and has become increasingly attractive to individuals, businesses, and governments on the path to sustainability.
