  2. Renewable energy - Wikipedia

    en.wikipedia.org/wiki/Renewable_energy

    Renewable energy in developing countries is an increasingly used alternative to fossil fuel energy, as these countries scale up their energy supplies and address energy poverty. Renewable energy technology was once seen as unaffordable for developing countries. [ 202 ]

    en.wikipedia.org/wiki/Renewable_resource

    Oceans often act as renewable resources. Sawmill near Fügen, Zillertal, Austria Global vegetation. A renewable resource (also known as a flow resource [note 1] [1]) is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale.

  4. Biofuel - Wikipedia

    en.wikipedia.org/wiki/Biofuel

    The production of biofuels can be very energy intensive, which, if generated from non-renewable sources, can heavily mitigate the benefits gained through biofuel use. A solution proposed to solve this issue is to supply biofuel production facilities with excess nuclear energy, which can supplement the power provided by fossil fuels. [ 111 ]

    In 2018, EIA expected that, after rising by 2.7% in 2018, U.S. energy-related carbon dioxide (CO 2) emissions would decrease by 2.5% in 2019 and by 1.0% in 2020 [20] due to a shift away from coal and toward renewables and natural gas. Renewable energy has the potential to reduce CO 2 emissions in three key energy use sectors: transport, heating ...

    Natural resource management is a discipline in the management of natural resources such as land, water, soil, plants, and animals—with a particular focus on how management affects quality of life for present and future generations. Hence, sustainable development is followed according to the judicious use of resources to supply present and ...

  8. Space-based solar power - Wikipedia

    en.wikipedia.org/wiki/Space-based_solar_power

    Renewable energy is a compelling approach, both philosophically and in engineering terms. Many renewable energy sources are limited in their ability to affordably provide the base load power required for global industrial development and prosperity, because of inherent land and water requirements.

  9. Solar energy - Wikipedia

    en.wikipedia.org/wiki/Solar_energy

    In 2011, a report by the International Energy Agency found that solar energy technologies such as photovoltaics, solar hot water, and concentrated solar power could provide a third of the world's energy by 2060 if politicians commit to limiting climate change and transitioning to renewable energy.
