Study Notes

Environmental Science - Energy Resources

  • Energy resources are materials used to generate electricity and power for human use.
  • There are two main types: renewable and non-renewable.
  • Renewable resources can be replaced readily:
    • Geothermal energy
    • Biogas
    • Hydroelectric energy
    • Solar energy
    • Wind energy
  • Non-renewable resources take a long time to replenish:
    • Fossil fuels (oil, coal, natural gas)
    • Nuclear energy
  • Fossil fuels are formed from the remains of dead organisms. They are drilled or mined before use.
  • Nuclear energy uses radioactive elements like uranium to create power.
  • Exploitation of energy resources leads to various environmental impacts:
    • Resource depletion (fossil fuels)
    • Soil erosion
    • Greenhouse gas increase and thermal pollution
    • Water and material pollution
    • Radiation pollution
    • Health hazards (e.g., cancer, birth defects)
  • Factors contributing to increased energy consumption:
    • Population growth
    • Increased demand for resources
    • Advancement in technologies
  • Major uses of energy resources:
    • Food production and agriculture
    • Transportation
    • Residential and commercial lighting
    • Cooling
    • Heating systems
    • Industrial processes
    • Electricity generation
  • Preventing soil erosion: Afforestation
  • Reducing CO2 emissions: Using alternative, renewable energy sources
  • Measures to mitigate environmental damage:
    • Waste minimization (sorting, recycling)
    • Precautionary and remedial measures
    • Appropriate government regulations and sanctions
