The question of optimal energy sources revolves around the comparison of sustainable resources, like solar, wind, hydro, and geothermal power, with finite resources such as fossil fuels (coal, oil, and natural gas)... Read more »
Substances extracted from the Earth that form naturally but at a rate far slower than human consumption are considered finite. Fossil fuels, such as coal, oil, and natural gas, exemplify this category.... Read more »
Energy sources are broadly categorized by their replenishment rates. Five examples of resources that regenerate on a human timescale include solar, wind, hydro, geothermal, and biomass energy. Conversely, five examples of resources... Read more »
