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.
