How are fossil fuels formed?
Fossil fuels are formed from the fossilised remains of plants and animals over millions of years.
Why are fossil fuels considered a finite resource?
Fossil fuels are considered a finite resource
Why are fossil fuels relied upon for power generation?
Fossil fuels are relied upon for power generation because they produce an immense amount of heat which can be used in the process of generating electricity.
How can fossil fuels be used to generate energy?
Fossil fuels can be burned to superheat water under pressure
What is fracking?
Fracking involves drilling into layers of shale rock deep in the earth to release pockets of gas.
Describe the process of fracking.
Water
What are the renewable energy sources?
Wind
What does renewable mean?
Renewable means that the resource can be constantly replenished while being used.
What are the positives of wind turbines?
Low maintenance
What are the negatives of wind turbines?
Only work when windy
Why is solar energy a good form of energy?
The sun produces a constant stream of solar energy that reaches Earth which in just one hour provides enough energy to power the world for one year.
How do photovoltaic cells work?
Light photons hit the PV cell which allows electrons to flow
What are the advantages of solar energy?
Low maintenance
What are the disadvantages of solar energy?
Seasonal fluctuations
How does tidal energy work?
The rise and fall of the tide forces water through turbines which drive generators to produce electricity.
What are the advantages of hydroelectric power?
Hydroelectric power is a very reliable and controllable energy source. The set-up costs are financially and environmentally expensive.
How is biofuel made?
Biofuel and biomass are created from organic matter which is burned to generate power.
What can be used for biofuel?
Biomass fuels include food and farm waste
What kind of energy is supplied by nuclear power?
Nuclear power supplies energy through the process of nuclear fission
