  2. Cost of electricity by source - Wikipedia

    en.wikipedia.org/wiki/Cost_of_electricity_by_source

    The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...

  3. Gas-fired power plant - Wikipedia

    en.wikipedia.org/wiki/Gas-fired_power_plant

    A gas-fired power plant, sometimes referred to as gas-fired power station, natural gas power plant, or methane gas power plant, is a thermal power station that burns natural gas to generate electricity. Gas-fired power plants generate almost a quarter of world electricity and are significant sources of greenhouse gas emissions. [1] However ...

  4. Power plant efficiency - Wikipedia

    en.wikipedia.org/wiki/Power_plant_efficiency

    The efficiency of a plant is the percentage of the total energy content of a power plant's fuel that is converted into electricity. The remaining energy is usually lost to the environment as heat unless it is used for district heating. Rating efficiency is complicated by the fact that there are two different ways to measure the fuel energy ...

  5. List of natural gas power stations in the United States

    en.wikipedia.org/wiki/List_of_natural_gas_power...

    In 2019 there were around 1900 natural gas power stations in the United States, of which about 800 belonged to electric utilities. [1] In 2019, these natural gas plants produced 38% of the United States electricity production, the highest percentage of any source above coal, nuclear and renewables. [2]

  6. Energy conversion efficiency - Wikipedia

    en.wikipedia.org/wiki/Energy_conversion_efficiency

    The energy efficiency of a fuel cell is generally between 40 and 60%; however, if waste heat is captured in a cogeneration scheme, efficiencies of up to 85% can be obtained. [24] World average fossil fuel electricity generation power plant as of 2008 [25] Chemical to electrical Gross output 39%, Net output 33% Electricity storage: Lithium-ion ...

    en.wikipedia.org/wiki/Natural_gas

    A cogeneration plant in Berlin Gas generates over 20% of world electricity Share of electricity production from gas A gas-fired power plant, sometimes referred to as gas-fired power station, natural gas power plant, or methane gas power plant, is a thermal power station that burns natural gas to generate electricity.

  8. Levelized cost of electricity - Wikipedia

    en.wikipedia.org/wiki/Levelized_cost_of_electricity

    It is used for investment planning and to compare different methods of electricity generation on a consistent basis. The more general term levelized cost of energy may include the costs of either electricity or heat. The latter is also referred to as levelized cost of heat [2] or levelized cost of heating (LCOH), or levelized cost of thermal ...

  9. Electricity generation - Wikipedia

    en.wikipedia.org/wiki/Electricity_generation

    They generate power by burning natural gas in a gas turbine and use residual heat to generate steam. At least 20% of the world's electricity is generated by natural gas. Water Energy is captured by a water turbine from the movement of water - from falling water, the rise and fall of tides or ocean thermal currents (see ocean thermal energy ...
