GEOG 106 Lecture Notes - Lecture 29: Fish Stock, Worldwatch Institute, Organic Matter
Document Summary
Energy resources that have not been converted or transformed. Ex. coal, oil, natural gas, hydro power, biomass, solar energy, wind energy. Energy transformed from conversion of primary energy. End use energy; the energy that is actually to do work. Ex. electricity generated from coal, oil, nuclear or wind to power a light bulb. For management purposes, usually classified by sector (industrial, commercial, residential, transportation) Difference between primary (extracted) and secondary (utilized) energy. Analogous to reducing the difference between water withdrawal and water. Efficiency" requires reducing the difference between primary & secondary energy consumption to increase efficiency. According to the worldwatch institute, worldwide, more than half of the energy that we consume does not provide us with useful services such as heat, light, and mobility. Resource base: the total quantity of a substance or property within the geosystem. Relatively easy to calculate for stock resources (e. g. coal), more difficult for flow resources at their availability is not static.
