  2. Environmental impact of electricity generation - Wikipedia

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

    The environmental impact of electricity generation from wind power is minor when compared to that of fossil fuel power. [58] Wind turbines have some of the lowest global warming potential per unit of electricity generated: far less greenhouse gas is emitted than for the average unit of electricity, so wind power helps limit climate change . [ 59 ]

  3. Environmental impact of nuclear power - Wikipedia

    The environmental effects of the artificial lakes are often weighted in arguments against construction of new plants, and during droughts such lakes have drawn media attention. [83] The Turkey Point Nuclear Generating Station is credited with helping the conservation status of the American Crocodile, largely an effect of the waste heat produced ...

    The study also found that the environmental and health costs of nuclear power, per unit of energy delivered, was €0.0019/kWh, which was found to be lower than that of many renewable sources including that caused by biomass and photovoltaic solar panels, and was thirty times lower than coal at €0.06/kWh, or 6 cents/kWh, with the energy ...

  5. Electronic waste - Wikipedia

    en.wikipedia.org/wiki/Electronic_waste

    Informal processing of e-waste in developing countries can lead to adverse human health effects and environmental pollution. [2] The growing consumption of electronic goods due to the Digital Revolution and innovations in science and technology , such as bitcoin , has led to a global e-waste problem and hazard.

  6. 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.

  7. Energy conservation - Wikipedia

    en.wikipedia.org/wiki/Energy_conservation

    Energy consumption by household type in the northeast United States in 2015. Energy monitoring through energy audits can achieve energy efficiency in existing buildings. 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 ...

  8. Corona discharge - Wikipedia

    en.wikipedia.org/wiki/Corona_discharge

    Corona discharge from high-voltage electric power transmission lines constitutes an economically significant waste of energy for utilities. In high-voltage equipment like cathode-ray-tube televisions , radio transmitters , X-ray machines , and particle accelerators , the current leakage caused by coronas can constitute an unwanted load on the ...

  9. Thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_generator

    Every human activity, transport and industrial process generates waste heat, being possible to harvest residual energy from cars, aircraft, ships, industries and the human body. [1] From cars the main source of energy is the exhaust gas. [32] Harvesting that heat energy using a thermoelectric generator can increase the fuel efficiency of the car.
