Wind power - Wikipedia

OverviewContentsHistoryWind farmsWind power capacity and productionEconomicsSmall-scale wind powerWind power is the use of air flow through wind turbines to mechanically power generators for electricity. Wind power, as an alternative to burning fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation, consumes no water, and uses little land. The net effects on the environment are far less problematic than those of nonrenewable power sources. Wind farms consist of many in…
