  2. Net energy gain - Wikipedia

    en.wikipedia.org/wiki/Net_energy_gain

    A net energy gain is achieved by expending less energy acquiring a source of energy than is contained in the source to be consumed. That is =. Factors to consider when calculating NEG is the type of energy, the way energy is used and acquired, and the methods used to store or transport the energy.

  3. Sustainable energy - Wikipedia

    en.wikipedia.org/wiki/Sustainable_energy

    To deliver reliable electricity from variable renewable energy sources such as wind and solar, electrical power systems require flexibility. [148] Most electrical grids were constructed for non-intermittent energy sources such as coal-fired power plants. [149]

  4. Low-carbon electricity - Wikipedia

    en.wikipedia.org/wiki/Low-carbon_electricity

    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 ...

  5. 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 ...

    consider one crucial option for energy security—call for the installation of new, more reliable forms of on-site electricity generation at mission critical, public safety facilities. E mergency preparedness and effective response depend entirely on the relia-bility and quality of a first responder’s energy supply. If primary grid power

    en.wikipedia.org/wiki/Renewable_energy

    As an energy source, biomass can either be used directly via combustion to produce heat, or converted to a more energy-dense biofuel like ethanol. Wood is the most significant biomass energy source as of 2012 [103] and is usually sourced from a trees cleared for silvicultural reasons or fire prevention.

    en.wikipedia.org/wiki/International_Energy_Agency

    The Energy Watch Group (EWG), a coalition of scientists and politicians which analyses official energy industry predictions, claims that the IEA has had an institutional bias towards traditional energy sources and has been using "misleading data" to undermine the case for renewable energy, such as wind and solar.

    Global energy consumption, measured in exajoules per year: Coal, oil, and natural gas remain the primary global energy sources even as renewables have begun rapidly increasing. [1] Primary energy consumption by source (worldwide) from 1965 to 2020 [2] World energy supply and consumption refers to the global supply of energy resources and its ...
