• What are the three main uses of energy in the UK?

  Transport, generating electricity, and heating
• What is the main source of energy currently used in the UK?

  Burning fossil fuels such as coal, oil, and gas
• What is a major environmental consequence of burning fossil fuels?

  It releases a large amount of carbon dioxide contributing to climate change
• What is the definition of renewable energy?

  A renewable energy resource is one that is being or can be replenished as it's used
• Name three commonly used renewable energy resources.

  Wind power, solar power, and hydroelectric power
• What are the two main advantages shared by all types of renewable energy resources?

  They will never run out and do not add carbon dioxide to the atmosphere
• Why are wind power and solar power considered unreliable?

  Because they depend on weather conditions, which can vary
• What is a disadvantage of hydroelectric power?

  It destroys habitats when dams are built and valleys are flooded
• Why is tidal power considered extremely reliable?

  Because the tide comes in and goes out twice a day
• How does geothermal energy generate electricity?

  By using heat from the earth
• What are biofuels produced from?

  Plant materials
• What does burning biofuels release, and why is it considered carbon neutral?

  It releases carbon dioxide, but the growing plants took in carbon dioxide
• What is a potential issue with using land for biofuels?

  It could push up the price of food
