Energy (renewable and non renewable)

• Energy Types


  • Solar Energy
  • Wind Energy
  • Hydroelectric
  • Coal
  • Natural Gas
  • Nuclear
• Renewable


  Can be used over and over again
• Non-renewable


  Can be used once and will eventually run out
• Renewable or Non-Renewable?


  • Solar Energy
  • Wind Energy
  • Hydroelectric
  • Coal
  • Natural Gas
  • Nuclear
• Solar Energy


  • Potentially infinite energy supply
  • Single dwellings can have own electricity supply
• Wind Energy


  • Potentially infinite energy supply
  • Can be found singularly but usually many together at wind farms
• Hydroelectric


  • Creates water reserves as well as energy supplies
  • Ready made fuel
• Coal


  • Cheap to mine and change to energy
  • Lasts longer than oil or gas
• Natural Gas


  • Ready made fuel
  • Quite cheap
• Nuclear


  • Small amount of radioactive material makes a lot of energy
  • Materials are quite cheap and long-lasting
  • No pollutants given off
• Advantages


  • Potentially infinite energy supply
  • Single dwellings can have own electricity supply
  • Can be found singularly but usually many together at wind farms
  • Creates water reserves as well as energy supplies
  • Ready made fuel
  • Cheap to mine and change to energy
  • Lasts longer than oil or gas
  • Quite cheap
  • Small amount of radioactive material makes a lot of energy
  • Materials are quite cheap and long-lasting
  • No pollutants given off
• Disadvantages


  • Making and installing solar panels can be expensive
  • Can be expensive to install
  • Arguably spoils the countryside
  • Expensive to build
  • Can cause flooding
  • Dams impact local hydrology
  • Gives off pollutants (e.g. greenhouse gases) when burnt
  • Limited supply
  • Gives off pollutants (e.g. greenhouse gases)
  • Expensive to run
  • Highly toxic and must be safely stored for up to 1000s of years which is expensive
  • Leakage, can have a devastating impact (e.g. Ukraine 1986)
• Resources can be defined as any material or product that we find useful
• Types of Resources


  • Physical resources, such as soil and coal which we take from the environment
• Non-renewable resources


  Can be used once and will eventually run out
• Renewable resources


  Can be used over and over again
• The sun will never run out
• The use of fossil fuels has led to environmental problems like air pollution, water pollution, acid rain, global warming, climate change, and the greenhouse effect.
• Fossil fuels such as coal, oil, and gas are examples of non-renewable resources that take millions of years to form.
• Non-Renewable energy sources are finite, meaning they will eventually run out.
• Coal is formed when dead plants and animals decompose under layers of mud and sand for millions of years. It contains carbon, hydrogen, oxygen, nitrogen, sulfur, and other minerals.
• Coal is formed when dead plants and animals decompose under layers of mud and sand.
• Oil forms deep underground from the remains of tiny marine organisms called plankton.
• Coal is formed from dead plants and trees buried deep underground under high pressure and heat.
• Oil is made up mostly of hydrocarbons, compounds containing only hydrogen and carbon atoms. Oil forms deep underground from the remains of tiny marine organisms called plankton.
• Natural Gas is found in porous rocks or trapped between impermeable rock layers.
