Study Notes
Energy Sources
- Energy for buildings, manufacturing, and transportation comes from various natural sources.
- Earth's core yields geothermal energy.
- Moon and sun's gravity create tidal energy.
- The sun's radiation creates wind and powers the hydrologic cycle, enabling photosynthesis.
- Photosynthesis converts solar energy into biomass (plants, algae, cyanobacteria).
- Biomass can be burned for biofuels (wood, biodiesel, bioethanol).
- Fossil fuels form from ancient biomass through geological processes (burial, heat, pressure).
Renewable vs. Non-renewable Energy
- Renewable energy sources replenish quickly (human lifespans).
- Examples: solar, wind, biomass.
- Non-renewable energy sources are finite and take a long time to replenish (millions of years).
- Examples: nuclear, fossil fuels.
- All energy sources have environmental and health costs.
- Energy distribution is uneven globally.
Energy Source Examples
- US generates less than 10% of its energy from renewable sources.
- Costa Rica generates over 99% of its electricity from renewables.
