Unit 6: (6-1 || 6-2} Renewable & Non-renewables, Global Energy Consumption

renewable energy sources

energy sources that can be replenished naturally, at or near the rate of consumption, and reused

nonrenewable energy sources

energy sources that exist in fixed amounts and cannot be replenished or regenerated in a timescale useable by humans

potentially renewable energy sources

biomass like wood, charcoal, animal waste, and biofuels like ethanol that can be potentially renewable if they're consumed at rates equal to or near regeneration

Developed countries energy use

High per-capita energy use due to high affluence, especially homes and cars. High use of commercial fuels, especially FFs

Developing countries energy use

Lower per-capita energy use due to low affluence, lack of electricity & car use. High use of subsistence fuels for personal home heating/cooking (wood, charcoal, etc.)

Industrialization/development & energy use

As countries develop, their total energy use increases, both due to pop. growth, and per-capita increase as affluence increases. Reliance on FFs especially increases

Commercial fuel sources

Fuel sources that are bought and sold on massive scales for industrial use like electricity generation or gasoline distribution. Primarily FFs.

Subsistence fuel sources

Fuel sources that are gathered by individuals (primarily in developing countries) for personal uses such as heating homes or cooking. Most commonly biomass such as wood, charcoal, dried animal waste or plant matter.
