Study Notes
Energy Resources
- Humans use energy from natural resources for various tasks, including communication, lighting, cooking, and transportation.
- Energy resources are categorized as renewable or non-renewable based on their generation methods.
Renewable Energy
- Renewable sources regenerate quickly or perpetually.
- Examples include hydropower, solar, wind, biomass, and geothermal energy.
- Hydropower uses moving water (rivers, tides, waves) to generate electricity.
- Solar power converts sunlight directly into electricity using solar panels.
- Wind energy uses wind turbines to convert wind energy into electricity.
- Biomass uses organic matter (wood, crops) to create electricity or fuels.
- Geothermal energy utilizes heat from within the Earth to produce steam for electricity generation.
- Renewable sources generally do not emit greenhouse gases.
Non-Renewable Energy
- Non-renewable sources take a very long time to form, and their supply is limited.
- Examples include fossil fuels (coal, oil, natural gas) and nuclear power.
- Fossil fuels are derived from the remains of ancient life, and take millions of years to form.
- Coal is formed from compressed plant matter.
- Oil and natural gas are formed from marine organisms.
- Nuclear power uses radioactive materials to generate electricity through nuclear fission.
- Burning fossil fuels releases greenhouse gases (CO2, methane, water vapor), contributing to global warming.
The Greenhouse Effect
- Sunlight striking Earth is partly reflected and absorbed.
- Greenhouse gases in the atmosphere trap heat, keeping Earth warm.
- Increased greenhouse gases can lead to global warming.
- CO2 and other gases contribute to the greenhouse effect.
Environmental Impacts
- Mining and extraction of certain resources can harm the environment.
- Fossil fuels release greenhouse gases when burned.
- Some renewable energy sources have minimal environmental impact.
