  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. Abiogenic petroleum origin - Wikipedia

    en.wikipedia.org/wiki/Abiogenic_petroleum_origin

    This hypothesis is different from biogenic oil in that the role of deep-dwelling microbes is a biological source for oil which is not of a sedimentary origin and is not sourced from surface carbon. Deep microbial life is only a contaminant of primordial hydrocarbons. Parts of microbes yield molecules as biomarkers.

  4. Sustainable energy - Wikipedia

    en.wikipedia.org/wiki/Sustainable_energy

    The role of non-renewable energy sources in sustainable energy is controversial. Nuclear power does not produce carbon pollution or air pollution, but has drawbacks that include radioactive waste , the risk of nuclear proliferation , and the risk of accidents .

    Alternatives to petroleum can include using other “cleaner” energy sources such as renewable energy, nuclear power, natural gas or biodiesel. Some of the alternatives have their strengths and limitations that might impact on the possibility of adopting them in the future. Using corn-based ethanol might be an alternative to using petroleum ...

  7. Bioremediation - Wikipedia

    en.wikipedia.org/wiki/Bioremediation

    Bioremediation is not specific to metals. In 2010 there was a massive oil spill in the Gulf of Mexico. Populations of bacteria and archaea were used to rejuvenate the coast after the oil spill. These microorganisms over time have developed metabolic networks that can utilize hydrocarbons such as oil and petroleum as a source of carbon and ...

  8. World energy resources - Wikipedia

    en.wikipedia.org/wiki/World_energy_resources

    Renewable resources are available each year, unlike non-renewable resources, which are eventually depleted. A simple comparison is a coal mine and a forest. While the forest could be depleted, if it is managed it represents a continuous supply of energy, vs. the coal mine, which once has been exhausted is gone.

  9. Resource depletion - Wikipedia

    en.wikipedia.org/wiki/Resource_depletion

    The depletion of resources has been an issue since the beginning of the 19th century amidst the First Industrial Revolution.The extraction of both renewable and non-renewable resources increased drastically, much further than thought possible pre-industrialization, due to the technological advancements and economic development that lead to an increased demand for natural resources.
