OTEC – ocean thermal energy conversion; Oxidation; Peat; Penrose Mechanism; Petroleum; Photovoltaics; Piezoelectricity; Pneumatics – compressed air; Products based on refined oil; Propellant

  3. Electricity generation - Wikipedia

    en.wikipedia.org/wiki/Electricity_generation

    Electricity generation is the process of generating electric power from sources of primary energy.For utilities in the electric power industry, it is the stage prior to its delivery (transmission, distribution, etc.) to end users or its storage, using for example, the pumped-storage method.

  4. Sources of electrical energy - Wikipedia

    en.wikipedia.org/wiki/Sources_of_electrical_energy

    The mechanical power needed to assist in this production is provided by a number of different sources. These sources are called prime movers, and include diesel, petrol and natural gas engines. Coal, oil, natural gas, biomass and nuclear energy are energy sources that are used to heat water to produce super-heated steam. Non-mechanical prime ...

  5. Natural resource - Wikipedia

    en.wikipedia.org/wiki/Natural_resource

    Waterfalls provide spring water for humans, animals and plants for survival and habitat for marine organisms. The water current can be used to turn turbines for hydroelectric generation. The ocean is an example of a natural resource. Ocean waves can be used to generate wave power, a renewable energy source.

  6. Environmental impact of electricity generation - Wikipedia

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

    Electric power systems consist of generation plants of different energy sources, transmission networks, and distribution lines. Each of these components can have environmental impacts at multiple stages of their development and use including in their construction, during the generation of electricity , and in their decommissioning and disposal.

  7. Energy industry - Wikipedia

    en.wikipedia.org/wiki/Energy_industry

    the nuclear power industry; the renewable energy industry, comprising alternative energy and sustainable energy companies, including those involved in hydroelectric power, wind power, and solar power generation, and the manufacture, distribution and sale of alternative fuels; and,

  8. Hydropower - Wikipedia

    en.wikipedia.org/wiki/Hydropower

    Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively ...

    en.wikipedia.org/wiki/Bioenergy

    The surface power production densities of a crop will determine how much land is required for production. The average lifecycle surface power densities for biomass, wind, hydro and solar power production are 0.30 W/m 2, 1 W/m 2, 3 W/m 2 and 5 W/m 2, respectively (power in the form of heat for biomass, and electricity for wind, hydro and solar ...
