  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. Electronic waste - Wikipedia

    en.wikipedia.org/wiki/Electronic_waste

    Most e-waste are composed of a mixture of metals like Cu, Al and Fe. They might be attached to, covered with or even mixed with various types of plastics and ceramics. E-waste has a horrible effect on the environment and it is important to dispose it with an R2 certifies recycling facility. [89]

  4. Energy conservation - Wikipedia

    en.wikipedia.org/wiki/Energy_conservation

    Commercial and industrial energy expenditures are determined by businesses entities and other facility managers. National energy policy has a significant effect on energy usage across all four sectors. Since the oil embargoes and price spikes of the 1970s, energy efficiency and conservation have been fundamental tenets of U.S. energy policy.

    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 ...

  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.

    An assessment of around 180 ocean technologies found that the GWP of ocean technologies varies between 15 and 105 g/kWh of CO 2 eq, with an average of 53 g/kWh CO 2 eq. [10] In a tentative preliminary study, published in 2020, the environmental impact of subsea tidal kite technologies the GWP varied between 15 and 37, with a median value of 23. ...

    en.wikipedia.org/wiki/Sustainable_energy

    The environmental dimension of sustainability includes greenhouse gas emissions, impacts on biodiversity and ecosystems, hazardous waste and toxic emissions, [7] water consumption, [9] and depletion of non-renewable resources. [6] Energy sources with low environmental impact are sometimes called green energy or clean energy. The economic ...

    [9] [10] This event sparked some of the current efforts to regulate the flows of electronic waste and ensure the health and safety of the global environment. The U.S. has not enacted a federal law to regulate the domestic recycling of e-waste, but, some states are implementing policies to address its increasing accumulation. [ 11 ]
