  2. Light pollution - Wikipedia

    en.wikipedia.org/wiki/Light_pollution

    For example, the Institution of Lighting Engineers in the United Kingdom provides its members with information about light pollution, the problems it causes, and how to reduce its impact. [148] Research in 2017 suggested that energy efficiency may not be enough to reduce the light pollution because of the rebound effect .

  3. Thermal pollution - Wikipedia

    en.wikipedia.org/wiki/Thermal_pollution

    Thermal pollution, sometimes called " thermal enrichment ", is the degradation of water quality by any process that changes ambient water temperature. Thermal pollution is the rise or drop in the temperature of a natural body of water caused by human influence. Thermal pollution, unlike chemical pollution, results in a change in the physical ...

  4. Environmental impact of electricity generation - Wikipedia

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

    Greenhouse gas emissions are one of the environmental impacts of electricity generation. Measurement of life-cycle greenhouse gas emissions involves calculating the global warming potential (GWP) of energy sources through life-cycle assessment. These are usually sources of only electrical energy but sometimes sources of heat are evaluated. [ 5 ]

  5. Life-cycle greenhouse gas emissions of energy sources

    Greenhouse gas emissions are one of the environmental impacts of electricity generation. Measurement of life-cycle greenhouse gas emissions involves calculating the global warming potential (GWP) of energy sources through life-cycle assessment. These are usually sources of only electrical energy but sometimes sources of heat are evaluated. [1]

  6. Pollution - Wikipedia

    en.wikipedia.org/wiki/Pollution

    t. e. Pollution is the introduction of contaminants into the natural environment that cause adverse change. [1] Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring ...

  7. Greenhouse gas emissions - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions

    The main sources of greenhouse gases due to human activity (also called carbon sources) are: Burning fossil fuels: Burning oil, coal and gas is estimated to have emitted 37.4 billion tonnes of CO 2-eq in 2023. [34] The largest single source is coal-fired power stations, with 20% of greenhouse gases (GHG) as of 2021. [35]

  8. Climate change mitigation - Wikipedia

    en.wikipedia.org/wiki/Climate_change_mitigation

    Climate change mitigation (or decarbonisation) is action to limit the greenhouse gases in the atmosphere that cause climate change. Climate change mitigation actions include conserving energy and replacing fossil fuels with clean energy sources. Secondary mitigation strategies include changes to land use and removing carbon dioxide (CO 2) from ...

  9. Environmental impact of the energy industry - Wikipedia

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

    The environmental impact of the energy industry is significant, as energy and natural resource consumption are closely related. Producing, transporting, or consuming energy all have an environmental impact. [3] Energy has been harnessed by human beings for millennia. Initially it was with the use of fire for light, heat, cooking and for safety ...
