    Study Notes

    Fossil Fuels

    • Fossil fuels include coal, oil, and natural gas, formed from the remains of living organisms millions of years ago.
    • About 75% of UK electricity is generated from power stations using fossil fuels.
    • Advantages:
      • High electricity generation capacity in single locations.
      • Easy to locate and cost-effective, especially coal, which is abundant.
      • Transporting oil and gas via pipelines is efficient.
      • Gas-powered plants are efficient and versatile in construction locations.
    • Disadvantages:
      • Non-renewable and will eventually exhaust.
      • Creates carbon dioxide, contributing to global warming.
      • Coal releases the most CO2; natural gas releases the least.
      • Sulfur dioxide from coal and oil contributes to health issues and acid rain.

    Nuclear Power

    • Main fuels are uranium and plutonium, which release energy through nuclear reactions, not combustion.
    • Heat boils water to produce steam, which drives turbines and generates electricity.
    • Advantages:
      • Nuclear energy does not emit carbon dioxide.
    • Disadvantages:
      • Non-renewable and poses risks of radioactive material release in accidents.
      • Radioactive waste remains hazardous for thousands of years and requires safe storage.

    Biofuels

    • Produced from plant materials, such as bioethanol from plant sugars and biodiesel from plant oils.
    • Renewable and can reduce overall CO2 emissions since plants absorb CO2 during growth.
    • Advantages:
      • Generally cheaper than fossil fuels and supported by tax incentives for greener vehicles.
      • Considered 'carbon neutral' by some; reduces emissions by 50-60%.
      • Decreases dependence on foreign oil and stabilizes prices.
      • Emits less particulate pollution compared to traditional fuels.
    • Disadvantages:
      • Requires land allocation that could be used for food production, potentially raising food prices.
      • Natural habitats may be lost, affecting biodiversity.
      • Limited availability of biofuels at gas stations discourages transition.
      • Burning biofuels, like corn, can release significant nitrous oxide emissions.

    Wind Energy

    • Wind turbines convert kinetic energy from wind into electricity.
    • Wind energy is a renewable resource driven by solar heat causing atmospheric convection.
    • Advantages:
      • No fuel costs and produces no waste or greenhouse gases.
      • Land beneath wind farms can still be used for agriculture.
      • Renewable and a viable energy source for remote areas.
    • Disadvantages:
      • Wind availability is unpredictable; not all areas are suitable for wind farms.
      • Aesthetic concerns from landscape changes and potential noise pollution.
      • Possible impact on bird migration patterns and local television reception.

    Wave Energy

    • Uses the kinetic energy from ocean waves to drive electricity generators.
    • Advantages:
      • Clean and renewable energy source.
      • Energy can be stored using dam systems until needed.
    • Disadvantages:
      • High construction costs for dams and environmental impact from flooding.
      • Relocation requirements for communities in flood zones and potential geological risks.
      • International disputes over river water supply management affected by dam installations.

    Solar Energy

    • Solar cells transform light energy directly into electricity; solar panels heat water.
    • Advantages:
      • Renewable with zero fuel costs and no harmful emissions.
    • Disadvantages:
      • High cost of solar cells and inefficiency leads to expensive electricity.
      • Limited effectiveness in non-sunny climates and inoperative at night.

    Geothermal Energy

    • Heat from radioactive decay in certain rocks provides energy; can utilize natural steam or pump cold water into heated rocks.
    • Advantages:
      • Renewable with no associated fuel costs and zero harmful emissions.
    • Disadvantages:
      • Limited suitable locations globally for geothermal energy exploitation.
