Wind power is the use of energy to generate useful work. Historically, wind power was used by , and , but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation. Today, wind power is generated almost completely with , generally grouped into and connected to the .

The harvest of electrical energy from the wind principally depends on the third power of the wind speed [51.1], as long as the rated power of the used wind turbines is not reached. Between the rated power of the turbines and the cut-off wind speed (see below) the harvested electrical energy is maximum and independent on. .
Here, we have to differentiate between different available solar energy technologies (Fig. 51.1a-d). Common photovoltaic (PV) plants and nonconcentrating solar. .
Temperature and humidity influence the conditions for wet cooling towers and water cooling of thermal power plants. In a wet cooling tower (or open-circuit cooling tower), warm water can be. .
Assessment of hydropower potentials requires the capture of areal instantaneous and seasonal averaged precipitation amounts in the catchment areas of rivers and. .
Cables in overhead transmission lines warm up in operation proportionally to the electrical resistance of the cable and the strength of the electrical.
