Geothermal power

Select from the list below the three types of fossil fuels.

Natural gas

Oil

Coal

Uranium

In a power station, what turns the turbine, which in turn powers an electricity generator?

Cold water

Steam

Oxygen

Methane

What is a biofuel?

A fuel that takes energy from atoms

A fuel that is taken from rainwater

A fuel that takes energy from waste products

A fuel that is taken from living or recently living organisms

What are the two elements that are used as nuclear fuels?

Uranium and plutonium

Uranium and americium

Plutonium and einsteinium

Uranium and actinium

Through which process is energy transferred from an unstable uranium/plutonium atom?

Nuclear fusion

Nuclear fission

Radioactive decay

Nuclear spallation

Do nuclear fuels release greenhouse gases when used?

Yes

Why are wind turbines unreliable?

If there's no wind then there's no electricity

They are hard to start up

They don't work efficiently

Unreliable electricity is being used to power the turbines

What type of liquid is used in hydroelectricity?

Distilled water

Rainwater

Acid rain

Liquid mercury

Which type of renewable energy resource uses the Sun's energy?

Geothermal

Hydroelectric

Solar

Tidal

Geothermal power uses what source of energy to create steam?

Alpha particles from uranium

Burning trees to create fire, which heats water

Burning ethanol to create fire, which heats water

Hot rocks underground

Select an advantage below that are caused by fossil fuels.

They don't produce any greenhouse gases

They can be easily stored

They are carbon-neutral

They are renewable

Select a disadvantage below that are caused by nuclear fuels.

They are very expensive

A high amount of the fuel is needed to generate enough electricity

The radioactive waste needs to be stored safely for centuries

They are unreliable

What is a disadvantage of using tidal power?

A large amount of water is needed

They are considered unsightly

It is not able to meet the global energy demand

They affect river estuaries and habitats

Select two disadvantages below that are caused by acid rain.

They lower the pH in rivers and lakes, killing marine wildlife

They can affect hydroelectric schemes

They can be consumed by humans and have health hazards

They can damage buildings and statues
