      Lesson details

      Learning outcome

      I can describe and compare different ways of generating electricity.

      Key learning points

      1. A non–renewable energy resource cannot be replenished as it is used.
      2. Non-renewable energy resources include fossil fuels (coal, oil and gas) and nuclear fuels.
      3. A renewable energy resource can be replenished as it is used.
      4. Renewable energy resources include biofuels, wind, hydroelectricity, geothermal, tidal, solar and water waves.
      5. Science can identify environmental issues, but political, social, ethical and economic considerations determine action.

      Keywords

      • Renewable energy resource - an energy resource that can be replenished as quickly as it is used or will not run out

      • Non-renewable energy resource - an energy resource that cannot be replenished as quickly as it is used and will eventually run out

      • Fossil fuels - energy sources formed over millions of years from the remains of dead organisms

      • Sustainable energy - using energy resources so that, in the future, there will be enough for people's needs

      Common misconception

      Renewable energy resources are more expensive than fossil fuels and cannot meet the demand for electricity on their own.

      Compare the cost of renewable energy resources with that of fossil fuels and explore advantages in energy storage technologies.

      Teacher tip

      Pupils could complete a structured research activity to find and summarise information around the key learning points for this lesson. You may also find several six–mark questions in past papers on this topic for pupils to practice.

      Q5.
      What is sustainable energy?

      consuming as much energy as possible
      Correct answer: using energy in a way that meets present needs without compromising future needs
      using non-renewable energy resources
      using only fossil fuels

      Q6.
      What role does energy efficiency play in sustainable energy?

      it has no impact on sustainability
      it increases energy consumption
      it only applies to renewable energy
      Correct answer: it reduces energy consumption and promotes sustainability
