A 2010 Harris Poll found strong support for wind power in Germany, other European countries, and the United States. [145] [146] [152] Public support in the United States has decreased from 75% in 2020 to 62% in 2021, with the Democratic Party supporting the use of wind energy twice as much as the Republican Party.

Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
Wind energy can be converted to mechanical or electrical energy. A traditional mechanical windmill can be used for pumping water or grinding grain. A modern electrical wind turbine converts the force of the wind to electrical energy for consumption on-site and/or export to the electricity grid. wind turbines – see wind energy.
Renewable energy (also called green energy) is energy made from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power, and hydropower. Bioenergy and geothermal power are also significant in some countries.
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. As of 2020 [update] , hundreds of thousands of large turbines , in installations known as wind farms , were generating over 650 gigawatts of power, with 60 GW added each year. [ 1 ]
Wind turbine – a turbine that converts wind energy into mechanical energy. Windmill – a machine which converts the energy of wind into rotational energy by means of vanes called sails or blades. Windpump – a windmill used for pumping water, either as a source of fresh water from wells, or for draining low-lying areas of land.
Flow visualization of wind speed contours around a house Wind engineering covers the aerodynamic effects of buildings Damaged wind turbines due to hurricane Maria. Wind engineering is a subset of mechanical engineering, structural engineering, meteorology, and applied physics that analyzes the effects of wind in the natural and the built environment and studies the possible damage ...
