Study Notes
Energy Sources
- Energy sources for our daily activities come from various natural sources like the earth's core, the sun, and moon's gravitational pull.
- Geothermal energy is generated from Earth's core.
- The gravitational pull of the moon and sun create tides.
- The sun's light energy powers the water cycle, creates wind, and enables photosynthesis.
- Through photosynthesis, plants, algae, and cyanobacteria create biomass that can be used for biofuels.
- Over millions of years, biomass transforms into fossil fuels through heat and pressure.
- Energy sources are classified as renewable or non-renewable based on their replenishment rate.
- Renewable energy sources, like solar, wind, and biomass, can be replenished within a human lifespan.
- Non-renewable energy sources, like nuclear energy and fossil fuels, take millions of years to form.
- All energy sources have environmental and health costs, and energy distribution varies globally.
- The US generates less than 10% of its energy from renewable sources, while Costa Rica generates over 99% of its electricity from renewables.
