  2. Energy & Fuels - Wikipedia

    en.wikipedia.org/wiki/Energy_&_Fuels

    Energy & Fuels is a peer-reviewed scientific journal published by the American Chemical Society. It was established in 1987. Its publication frequency switched from bimonthly to monthly in 2009. The editor-in-chief is Hongwei Wu ( Curtin University ). According to the American Chemical Society, Energy & Fuels publishes reports of research in ...

  3. Fuel - Wikipedia

    en.wikipedia.org/wiki/Fuel

    Chemical fuels are substances that release energy by reacting with substances around them, most notably by the process of combustion . Chemical fuels are divided in two ways. First, by their physical properties, as a solid, liquid or gas. Secondly, on the basis of their occurrence: primary (natural fuel) and secondary (artificial fuel).

  4. Energy in the United States - Wikipedia

    en.wikipedia.org/wiki/Energy_in_the_United_States

    Energy in the United States is obtained from a diverse portfolio of sources, although the majority came from fossil fuels in 2021, as 36% of the nation's energy originated from petroleum, 32% from natural gas, and 11% from coal. Electricity from nuclear power supplied 8% and renewable energy supplied 12%, which includes biomass, wind, hydro ...

  5. Fossil fuel - Wikipedia

    en.wikipedia.org/wiki/Fossil_fuel

    Fossil fuel. A fossil fuel [a] is a carbon compound - or hydrocarbon -containing material such as coal, oil, and natural gas, [2] formed naturally in the Earth's crust from the remains of prehistoric organisms (animals, plants and planktons ), a process that occurs within geological formations. Reservoirs of such compound mixtures can be ...

  6. Cost of electricity by source - Wikipedia

    en.wikipedia.org/wiki/Cost_of_electricity_by_source

    In 2014, the US Energy Information Administration recommended [13] that levelized costs of non-dispatchable sources such as wind or solar be compared to the "levelized avoided cost of energy" (LACE) rather than to the LCOE of dispatchable sources such as fossil fuels or geothermal. LACE is the avoided costs from other sources divided by the ...

  7. Renewable energy - Wikipedia

    en.wikipedia.org/wiki/Renewable_energy

    Renewable energy in developing countries is an increasingly used alternative to fossil fuel energy, as these countries scale up their energy supplies and address energy poverty. Renewable energy technology was once seen as unaffordable for developing countries. [ 193 ]

  8. Energy - Wikipedia

    en.wikipedia.org/wiki/Energy

    Human civilization requires energy to function, which it gets from energy resources such as fossil fuels, nuclear fuel, or renewable energy. The Earth's climate and ecosystems processes are driven by the energy the planet receives from the Sun (although a small amount is also contributed by geothermal energy).

  9. Energy density - Wikipedia

    en.wikipedia.org/wiki/Energy_density

    The higher the energy density of the fuel, the more energy may be stored or transported for the same amount of volume. The energy of a fuel per unit mass is called its specific energy. The adjacent figure shows the gravimetric and volumetric energy density of some fuels and storage technologies (modified from the Gasoline article).
