  2. Environmental impact of electricity generation - Wikipedia

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

    Nuclear energy and renewable energy have reduced environmental costs by decreasing CO 2 emissions resulting from energy consumption. [42] There is a catastrophic risk potential if containment fails, [43] which in nuclear reactors can be brought about by overheated fuels melting and releasing large quantities of fission products into the ...

  3. Life-cycle greenhouse gas emissions of energy sources

    en.wikipedia.org/wiki/Life-cycle_greenhouse_gas...

    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. ...

  4. Sustainable energy - Wikipedia

    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 ...

  5. Low-carbon electricity - Wikipedia

    en.wikipedia.org/wiki/Low-carbon_electricity

    Globally almost 40% of electricity generation came from low-carbon sources in 2020: about 10% being nuclear power, almost 10% wind and solar, and around 20% hydropower and other renewables. [1] Very little low-carbon power comes from fossil sources, mostly due to the cost of CCS technology.

  6. Environmental impacts of lithium-ion batteries - Wikipedia

    en.wikipedia.org/wiki/Environmental_impacts_of...

    Lithium-ion batteries must be handled with extreme care from when they're created, to being transported, to being recycled. Recycling is extremely vital to limiting the environmental impacts of lithium-ion batteries. By recycling the batteries, emissions and energy consumption can be reduced as less lithium would need to be mined and processed ...

  7. Environmental impact of the energy industry - Wikipedia

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

    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 ...

  8. 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.

  9. Nuclear power debate - Wikipedia

    en.wikipedia.org/wiki/Nuclear_power_debate

    Stewart Brand at a 2010 debate, "Does the world need nuclear energy?" [31]At the 1963 ground-breaking for what would become the world's largest nuclear power plant, President John F. Kennedy declared that nuclear power was a "step on the long road to peace," and that by using "science and technology to achieve significant breakthroughs", we could "conserve the resources" to leave the world in ...
