  2. Energy conservation - Wikipedia

    en.wikipedia.org/wiki/Energy_conservation

    An energy audit is an inspection and analysis of energy use and flows for energy conservation in a structure, process, or system intending to reduce energy input without negatively affecting output. Energy audits can determine specific opportunities for energy conservation and efficiency measures as well as determine cost-effective strategies ...

  3. Energy recycling - Wikipedia

    en.wikipedia.org/wiki/Energy_recycling

    Energy recycling is the energy recovery process of using energy that would normally be wasted, usually by converting it into electricity or thermal energy.Undertaken at manufacturing facilities, power plants, and large institutions such as hospitals and universities, it significantly increases efficiency, thereby reducing energy costs and greenhouse gas pollution simultaneously.

  4. Energy crop - Wikipedia

    en.wikipedia.org/wiki/Energy_crop

    A frequently used and cost-efficient method is to convert a plant to run on a different fuel (such as energy crops/biomass). In some instances, torrefaction of biomass may benefit the power plant if energy crops/biomass is the material the converted fossil fuel power plant will be using. [16]

  5. Sustainable energy - Wikipedia

    en.wikipedia.org/wiki/Sustainable_energy

    Most studies use a working assumption that CCS can capture 85–90% of the carbon dioxide (CO 2) emissions from a power plant. [113] [114] Even if 90% of emitted CO 2 is captured from a coal-fired power plant, its uncaptured emissions are still many times greater than the emissions of nuclear, solar or wind energy per unit of electricity produced.

  6. Environmental impact of electricity generation - Wikipedia

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

    As well as greenhouse gases, these power plants emit nitrogen oxides (NOx) [20] but this is less dangerous than NOx from gas appliances in houses. [21] The efficiency of gas-fired power plants can be improved by co-generation and geothermal (combined heat and power) methods. Process steam can be extracted from steam turbines.

  7. Rural electrification - Wikipedia

    en.wikipedia.org/wiki/Rural_electrification

    In September 2018, the U.S. Department of Agriculture said it would spend $398.5 million in infrastructure projects, by way of loans, that seek to improve electricity service in rural areas. The program is called the Electric Infrastructure Loan Program. Of the $398.5 million, $43 million will be to invest in smart grid technology.

  8. Climate change mitigation - Wikipedia

    en.wikipedia.org/wiki/Climate_change_mitigation

    Large amounts of heat in power plants and in motors of vehicles go to waste. The actual amount of energy consumed is significantly lower at 116,000 TWh. [95] Energy conservation is the effort made to reduce the consumption of energy by using less of an energy service. One way is to use energy more efficiently. This means using less energy than ...

  9. Fossil fuel power station - Wikipedia

    en.wikipedia.org/wiki/Fossil_fuel_power_station

    In some instances, torrefaction of biomass may benefit the power plant if energy crops/biomass is the material the converted fossil fuel power plant will be using. [41] Also, when using energy crops as the fuel, and if implementing biochar production, the thermal power plant can even become carbon negative rather than just carbon neutral.
