Name three fossil fuels.
Coal, oil and gas.
1 of 12
What is the process by which energy is produced in a nuclear power station?
Nuclear fission.
2 of 12
What form of energy is stored in the water in the top resevoir of a pumped storage scheme?
Gravitational potential energy.
3 of 12
Why is wave power likely to be less reliable than tidal power?
There are always two tides a day (tides depend on gravitational pull of the Sun and Moon), but on a calm day there may not be many waves (waves depend on winds, which are unreliable).
4 of 12
Why are large numbers of solar cells often joined to make a solar panel?
Each solar cell only produces a small amount of electricity.
5 of 12
Why are only a few places in the world able to have geothermal power stations?
In many places in the world the hot rocks are too far below the surface to be used.
6 of 12
What type of area would be most suitable for a wind farm?
A large, flat areas of high ground.
7 of 12
What is the difference between a renewable energy resource and a non-renewable energy resource?
A renewable energy source is produced as fast as it is used. A non-renewable energy source is one that is used at a much faster rate than it is produced.
8 of 12
Which gas, released by the burning of coal, causes acid rain?
Sulfur dioxide.
9 of 12
Give two advantages of overhead cables compared with underground cables.
Overhead cables are easier to repair and are cheaper.
10 of 12
What sort of transformers are used at local substations?
A step-down transformer.
11 of 12
Why does the demand for electricity vary between summer and winter?
The demand increases in winter because it gets colder so more electricity is used heating homes.
