  2. Non-renewable resource - Wikipedia

    en.wikipedia.org/wiki/Non-renewable_resource

    A coal mine in Wyoming, United States. Coal, produced over millions of years, is a finite and non-renewable resource on a human time scale.. A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. [1]

  3. 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. [ 201 ]

  4. Renewable energy debate - Wikipedia

    en.wikipedia.org/wiki/Renewable_energy_debate

    The transition to renewable energy depends on non-renewable resources, such as mined metals. [38] Manufacturing of photovoltaic panels, wind turbines and batteries requires significant amounts of rare-earth elements [ 39 ] which has significant social and environmental impact if mined in forests and protected areas.

  5. Sustainable energy - Wikipedia

    en.wikipedia.org/wiki/Sustainable_energy

    Energy storage helps overcome barriers to intermittent renewable energy and is an important aspect of a sustainable energy system. [154] The most commonly used and available storage method is pumped-storage hydroelectricity , which requires locations with large differences in height and access to water. [ 154 ]

  6. Renewable resource - Wikipedia

    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.

  7. Sustainable engineering - Wikipedia

    en.wikipedia.org/wiki/Sustainable_engineering

    Energy Conservation: Probably the most important part of building green is energy conservation. By implementing passive design , structural insulated panels (SIPs), efficient lighting, and renewable energy like solar energy and geothermal energy , a home can benefit from reduced energy consumption or qualify as a net zero energy home.

  8. Peak water - Wikipedia

    en.wikipedia.org/wiki/Peak_water

    Peak ecological water, where ecological and environmental constraints are overwhelming the economic benefits provided by water use [1] Peak non-renewable water, where groundwater aquifers are being overpumped (or contaminated) faster than nature recharges them (this example is most like the peak oil debate)

  9. Energy conservation - Wikipedia

    en.wikipedia.org/wiki/Energy_conservation

    Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less and better sources of energy for continuous service) or changing one's behavior to use less and better source of service (for example, by driving vehicles which consume renewable ...
