  2. Water-energy nexus - Wikipedia

    en.wikipedia.org/wiki/Water-energy_nexus

    Hybrid Sankey diagram of 2011 U.S. interconnected water and energy flows. The water-energy nexus is the relationship between the water used for energy production, [1] including both electricity and sources of fuel such as oil and natural gas, and the energy consumed to extract, purify, deliver, heat/cool, treat and dispose of water (and wastewater) sometimes referred to as the energy intensity ...

  3. Solar-powered desalination unit - Wikipedia

    en.wikipedia.org/wiki/Solar-powered_desalination...

    The sun's energy heats water to the point of evaporation. As the water evaporates, water vapor rises, condensing on the glass surface for collection. This process removes impurities, such as salts and heavy metals, and eliminates microbiological organisms. The end result is water cleaner than the purest rainwater. [citation needed]

  4. Solar desalination - Wikipedia

    en.wikipedia.org/wiki/Solar_desalination

    The feed water passes in parallel through all the cells, providing a continuous flow of permeate and brine. Although this is a well-known process electrodialysis is not commercially suited for seawater desalination, because it can be used only for brackish water (TDS < 1000 ppm). [38]

  5. Renewable energy - Wikipedia

    en.wikipedia.org/wiki/Renewable_energy

    Although almost all forms of renewable energy cause much fewer carbon emissions than fossil fuels, the term is not synonymous with low-carbon energy. Some non-renewable sources of energy, such as nuclear power, [contradictory] generate almost no emissions, while some renewable energy sources can be very carbon-intensive, such as the burning of ...

  6. Non-renewable resource - Wikipedia

    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]

  7. Carbon-neutral fuel - Wikipedia

    en.wikipedia.org/wiki/Carbon-neutral_fuel

    An article suggests that this technology does not create an alternative to fossil fuel but rather converting renewable energy into liquid fuel. The article also states that the energy return on energy invested using fossil diesel is 18 times higher than that for e-diesel. [61]

    Fresh and unpolluted water accounts for 0.003% of total water available globally. [3] According to World Bank, India and Brazil has the highest freshwater resources per capita in 2024, ″renewable internal freshwater resources flows refer to internal renewable resources (internal river flows and groundwater from rainfall) in the country.″ [4]

    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.
