  2. Non-renewable resource - Wikipedia

    en.wikipedia.org/wiki/Non-renewable_resource

    Earth minerals and metal ores are examples of non-renewable resources. The metals themselves are present in vast amounts in Earth's crust, and their extraction by humans only occurs where they are concentrated by natural geological processes (such as heat, pressure, organic activity, weathering and other processes) enough to become economically viable to extract.

  3. Biomass (energy) - Wikipedia

    en.wikipedia.org/wiki/Biomass_(energy)

    Biomass (in the context of energy generation) is matter from recently living (but now dead) organisms which is used for bioenergy production. There are variations in how such biomass for energy is defined, e.g. only from plants, [8] or from plants and algae, [9] or from plants and animals. [10]

    These are produced by conversion from a primary energy source. Primary energy is used as a measure in energy statistics in the compilation of energy balances, [5] as well as in the field of energetics. In energetics, a primary energy source (PES) refers to the energy forms required by the energy sector to generate the supply of energy carriers ...

  9. 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.
