  2. Electrical resistance heating - Wikipedia

    en.wikipedia.org/wiki/Electrical_resistance_heating

    Electrical resistance heating (ERH) is an intensive in situ environmental remediation method that uses the flow of alternating current electricity to heat soil and groundwater and evaporate contaminants. [1] Electric current is passed through a targeted soil volume between subsurface electrode elements.

  3. Energy conservation - Wikipedia

    en.wikipedia.org/wiki/Energy_conservation

    An energy audit is an inspection and analysis of energy use and flows for energy conservation in a structure, process, or system intending to reduce energy input without negatively affecting output. Energy audits can determine specific opportunities for energy conservation and efficiency measures as well as determine cost-effective strategies ...

  4. Environmental technology - Wikipedia

    en.wikipedia.org/wiki/Environmental_technology

    Reducing the use of electricity causes less fossil fuels to be burned to provide that electricity. And it refers to the practice of using less energy through changes in individual behaviors and habits. The main emphasis for energy conservation is the prevention of wasteful use of energy in the environment, to enhance its availability.

  5. Remediation of contaminated sites with cement - Wikipedia

    en.wikipedia.org/wiki/Remediation_of...

    A 1,300,000-square-foot (120,000 m 2) complex of mixed residential, office, retail and commercial space is being built on 15 acres (61,000 m 2) of former industrial land in downtown Victoria that was contaminated by lead. 10 tonnes of soil was treated with cement, which was mixed into the soil on site simply by using an excavator bucket. The ...

  6. Environmental impact of electricity generation - Wikipedia

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

    All forms of electricity generation have some form of environmental impact, [1] but coal-fired power is the dirtiest. [2] [3] [4] This page is organized by energy source and includes impacts such as water usage, emissions, local pollution, and wildlife displacement.

  7. 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.

  8. Environmental impact of the energy industry - Wikipedia

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

    Energy conservation refers to efforts made to reduce energy consumption. Energy conservation can be achieved through increased efficient energy use, in conjunction with decreased energy consumption and/or reduced consumption from conventional energy sources. Energy conservation can result in increased financial capital, environmental quality ...

  9. Soil contamination - Wikipedia

    en.wikipedia.org/wiki/Soil_contamination

    Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste .
