This page covers section 10.6.2 and 10.6.3 of the CIE O Level specification.

  • 10.6.2 -The strategies and techniques used to increase energy supplies.

  • 10.6.3 - An evaluation of the strategies and techniques used to manage energy supplies; including sustainable.

Increasing energy supplies

Increasing energy supplies

  • Due to the increasing demand for energy, all countries need to ensure that they have sufficient energy to meet the demand

  • There are three main strategies to increase energy supplies:

    1. Increase the use of renewable energy

    2. Continue to exploit fossil fuels

    3. Further develop the use of nuclear fuel

  • Each of these strategies varies in its effectiveness

Effectiveness of strategies to increase energy supplies

Effectiveness of strategies to increase energy supplies

  • The strategies used to increase energy supplies vary between countries

  • The choices governments make depend on the resources and finances available

  • Sustainability is increasingly important

  • This may be environmental sustainability but could also be economic or social sustainability

Increase the use of renewable energy

Advantages

  • Sustainability: Renewable energy sources will not run out; they are infinite

  • Environmental benefits: Significantly lower greenhouse gas emissions compared to fossil fuels

  • Energy security: Reduces dependency on imported fuels, as renewable resources are locally available

  • Job Creation: Expanding industries like solar and wind energy create many new jobs

Disadvantages

  • Reliability: Some renewables (e.g., solar, wind) are not always available, requiring energy storage

  • High costs: Setting up renewable energy infrastructure can be expensive

  • Land Use: Large-scale renewable projects (like solar farms or wind farms) require significant land, potentially leading to habitat disruption

  • Technological Challenges: Energy storage technologies (like batteries) are still developing

Continue to exploit fossil fuels

Advantages

  • Existing infrastructure: Systems are already in place for extraction, refining, and distribution

  • High energy density: Fossil fuels provide a lot of energy relative to their volume or mass

  • Reliability: Fossil fuel power plants provide a consistent and controllable energy supply

  • Economic importance: Fossil fuel industries contribute significantly to many economies

Disadvantages

  • Environmental damage: Major contributor to air pollution, oil spills, and habitat destruction

  • Climate change: Burning fossil fuels is the largest source of carbon dioxide emissions

  • Finite Resource: Fossil fuels are non-renewable and will eventually run out

  • Geopolitical tensions: Fossil fuel resources can create or exacerbate international conflicts over access and control

Further develop the use of nuclear fuel

Advantages

  • Low greenhouse gas emissions: Once built, nuclear plants emit minimal CO₂ compared to fossil fuel plants

  • High energy output: Nuclear fuel produces a very high amount of energy from a small amount of fuel

  • Reliability: Nuclear power plants can run consistently, unlike intermittent renewable sources

  • Energy security: Reduces dependence on fossil fuels, improving national energy autonomy

Disadvantages

  • Nuclear accidents: Disasters like Chernobyl and Fukushima mean that people do not trust the safety of nuclear energy

  • Radioactive waste: Long-term storage of nuclear waste is expensive and difficult, as it takes a long time to decay and become safe

  • High costs: Building nuclear power plants is costly and takes many years. Decommissioning plants is also expensive

  • Public opposition: There is significant public fear about nuclear energy development due to health risks and links to cancer
