• What should you be able to describe at the end of the video?

  The main renewable sources of energy and their advantages and disadvantages
• 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

  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 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 hydroelectric power not suitable for the UK?

  Because it is only useful in countries with lots of rivers
• What is the reliability of tidal power?

• Why is geothermal energy not widely used in the UK?

  It is not really used very much in the UK
• What is a common issue with renewable energy generation in the UK?

  Most energy use is for transport, which relies on fossil fuels
• What are biofuels produced from?

  Plant materials
• What is the environmental impact of burning biofuels?

  It releases carbon dioxide, but it is considered carbon neutral
• What is a potential problem with using land to grow crops for biofuels?

  It could push up the price of food
• What are the advantages and disadvantages of renewable energy sources?
