Renewable energy

Renewable energy  is energy that is collected from renewable resources, which are naturally replenished on a human scale, such as sunlight, wind, rain, tides, waves and geothermal heat. [2]  Renewable energy often provides energy in four important areas: power generation, air and water heating and cooling, rural transportation and energy services (off grid) . [3]

Airflow can be used to operate wind turbines. Modern wind turbines on an industrial scale range from about 600 kW to 5 MW of rated power, although turbines with a nominal power of 1.5-3 MW have become the most common for commercial use. The largest generation capacity of a single onshore wind turbine installed reached 7.5 MW in 2015. The available wind power is a function of the cube of the wind speed, so that when the wind speed increases, the power increases. until you reach the maximum power. particular turbine. [41] Areas with stronger and more consistent winds, such as offshore sites and high altitude, are prime locations for wind farms. Loading times generally fullThe wind turbines vary between 16 and 57% per year, but could be higher in particularly favorable offshore sites. [42] Continue reading “CONSUMER TECHNOLOGIES”


Other renewable energy technologies are still under development and include cellulosic ethanol, dry and hot geothermal energy, and marine energy. [154]  These technologies are not yet widely proven or have limited commercialization. Many are on the horizon and may have potential comparable to other renewable energy technologies, but they still depend on attracting sufficient attention and funding for research, development and demonstration (RD & D) . [154]
