  2. Wind power - Wikipedia

    en.wikipedia.org/wiki/Wind_power

    Arrays of large turbines, known as wind farms, have become an increasingly important source of renewable energy and are used in many countries as part of a strategy to reduce their reliance on fossil fuels. Wind turbine design is the process of defining the form and specifications of a wind turbine to extract energy from the wind. [181]

  3. Environmental impact of wind power - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of...

    The Vattenfall utility company study found Hydroelectric, nuclear stations and wind turbines to have far less greenhouse emissions than other sources studied.. A typical study of a wind farm's Life cycle assessment, when not connected to the electric grid, usually results in similar findings as the following 2006 analysis of 3 installations in the US Midwest, where the carbon dioxide (CO 2 ...

  4. Life-cycle greenhouse gas emissions of energy sources

    en.wikipedia.org/wiki/Life-cycle_greenhouse_gas...

    For example, the total life cycle emissions from wind power may have lessened since publication. Similarly, due to the time frame over which the studies were conducted, nuclear Generation II reactor's CO 2 e results are presented and not the global warming potential of Generation III reactors. Other limitations of the data include: a) missing ...

  5. Wind turbine - Wikipedia

    en.wikipedia.org/wiki/Wind_turbine

    Wind turbines are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels. One study claimed that, as of 2009, [update] wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and the most favorable social ...

  6. Life-cycle assessment - Wikipedia

    en.wikipedia.org/wiki/Life-cycle_assessment

    Life cycle energy analysis (LCEA) is an approach in which all energy inputs to a product are accounted for, not only direct energy inputs during manufacture, but also all energy inputs needed to produce components, materials and services needed for the manufacturing process. [110] With LCEA, the total life cycle energy input is established. [111]

    One of the primary complaints from opponents of wind power is the noise turbines produce.

  8. Renewable energy - Wikipedia

    en.wikipedia.org/wiki/Renewable_energy

    The two most important forms of renewable energy, solar and wind, are intermittent energy sources: they are not available constantly, resulting in lower capacity factors. In contrast, fossil fuel power plants, nuclear power plants and hydropower are usually able to produce precisely the amount of energy an electricity grid requires at a given ...

  9. Wind farm - Wikipedia

    en.wikipedia.org/wiki/Wind_farm

    Iowa is the leading state in terms of wind energy accounting for nearly 40% of total energy production in 2019. The Alta Wind Energy Center (1,020 MW) in California is the nation's largest wind farm in terms of capacity. Altamont Pass Wind Farm is the largest wind farm in the U.S. in terms of the number of individual turbines. [112]
