Study Notes
Energy Sources
- Energy for human needs comes from various natural sources, including geothermal energy, tidal energy, solar energy, and biomass.
- The sun's electromagnetic radiation drives wind and the water cycle.
- Plants, algae, and cyanobacteria convert solar energy into biomass which can be used for biofuels.
- Fossil fuels result from the geological transformation of ancient biomass.
Renewable Energy
- Renewable energy resources can be replenished in a relatively short time.
- Examples include solar, wind, and biomass energy.
Non-Renewable Energy
- Non-renewable energy resources are finite and cannot be replenished within a human timeframe.
- Examples include nuclear energy and fossil fuels.
- Fossil fuels take millions of years to form.
Environmental and Health Impacts
- All energy sources have environmental and health costs.
- Energy distribution is uneven across nations.
Energy Generation by Country Examples
- The United States generates less than 10% of its energy from renewable sources.
- Costa Rica generates over 99% of its electricity from renewable sources.
