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.
