Wind power is considered a sustainable, renewable energy source, and has a much smaller impact on the environment compared to burning fossil fuels. Wind power is variable, so it needs energy storage or other dispatchable generation energy sources to attain a reliable supply of electricity. Land-based (onshore) wind farms have a greater visual ...
Historically, wind power was used by sails, windmills and windpumps, 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 wind turbines, generally grouped into wind farms and connected to the electrical grid.
Wind power in Russia – Russia has a long history of small-scale wind power use, but the country has not yet developed large-scale commercial wind energy production. Wind power in Scotland – wind power is Scotland's fastest growing renewable energy technology, with 2,574 MW of installed capacity as of April 2011. Wind power in Serbia
Wind turbines can be very large, reaching over 260 m (850 ft) tall with blades 110 m (360 ft) long, [120] and people have often complained about their visual impact. Environmental impact of wind power includes effect on wildlife, but can be mitigated if proper strategies are implemented. [121]
Some wind turbines on public display go one further, with observation decks beneath their nacelles. The observation decks are accessed with stairs inside the tower. Austria. Wind turbine at Pesendorf, Lichtenegg, Lower Austria. Type Enercon E-66 [17] One turbine at the wind farm Energiepark near Bruck an der Leitha, Type Enercon E-66; Canada
The 2011 NREL report, Large-Scale Offshore Wind Power in the United States, analyzes the current state of the offshore wind energy industry. According to the report, offshore wind resource development would help the country to achieve 20% of its electric power from wind by 2030 and to revitalize the manufacturing sector.
Wind-turbine blades in laydown yard awaiting installation. The primary application of wind turbines is to generate energy using the wind. Hence, the aerodynamics is a very important aspect of wind turbines. Like most machines, wind turbines come in many different types, all of them based on different energy extraction concepts.
Wind power [ edit ] In response to the growing need for technical training involving wind power , TSTC Sweetwater created the first community college wind-energy program in Texas, [ 4 ] and constructed a demonstration 2 MW 60 Hz DeWind D8.2 prototype wind turbine for student training in 2007. [ 5 ]
