In electricity generation, a generator [1] is a device that converts motion-based power ( potential and kinetic energy) or fuel-based power ( chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even マスラハはイスラーム世界に近代化の波が押し寄せた19世紀末や、政治イデオロギーとしてのイスラーム主義が議論される現在など、イスラーム世界が大問題に直面している時代にイスラーム法学者達によって盛んにとりあげられてきた概念でもある。 Renewable energy, green energy, or low-carbon energy is energy from renewable resources that are naturally replenished on a human timescale.Renewable resources include sunlight, wind, the movement of water, and geothermal heat.
