Q

Define energy dependency

A

A situation whereby a country or region becomes reliant on certain sources of energy.

28
Q

How does nuclear energy work?

A

Nuclear reactors create heat, producing steam, which turns a turbine, creating electricity.

29
Q

How important is nuclear energy?

A

Quite important as it provides around 18% of UK energy and is environmentally large scale.

30
Q

Now much does nuclear energy cost?

A

£92.50 mwh, which is more expensive than renewable energy.

Q

What are the environmental impacts of nuclear energy?

A

Accidents can cause radioactive radiation and water and steam is used to cool the reactor.

32
Q

What are the advantages of nuclear energy?

A

A small amount of greenhouse gases emissions are produced.

33
Q

What are the disadvantages of nuclear energy?

A

If someone goes wrong there’s large-scale consequences/problems.
