In 2020, wind supplied almost 1600 of electricity, which was over 5% of worldwide electrical generation and about 2% of energy consumption. With over 100 added during 2020, mostly , global installed wind power capacity reached more than 730 GW. But to help meet the 's goals to , analysts say it should expand much faster – by over 1%. Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.
[pdf] Concentrated solar power (CSP, also known as concentrating solar power, concentrated solar thermal) systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight into a receiver. Electricity is generated when the concentrated light is converted to heat (solar thermal energy), which drives a heat engine (usually a steam turbine) connected to an. Comparison between CSP and other electricity sourcesAs a thermal energy generating power station, CSP has more in common with such as coal, gas, or geothermal. A CSP plant can incorporate , which stores energy eith. .
A legend has it that used a "burning glass" to concentrate sunlight on the invading Roman fleet and repel them from . In 1973 a Greek scientist, Dr. Ioannis Sakkas, curious about whether Archimede. .
CSP is used to produce electricity (sometimes called solar thermoelectricity, usually generated through ). Concentrated solar technology systems use or with systems to focus a larg.
[pdf] In Latvia, renewable energy sources account for a significant portion of the country’s electricity generation, with a target of 57% by 2030 [1]. Hydroelectric power is the main source of renewable electricity in Latvia, followed by solar, wind and biomass cogeneration plants.
