How does cost decide which power stations get built?

Investors and government back whichever source generates most cheaply across a station's lifetime, which is why wind and solar, now among the cheapest sources, have expanded fastest.

How can a war overseas change British energy policy?

Interrupted supplies and soaring prices push government to generate more at home, to store more gas and to speed up renewable building.

How does the planning system shape where energy is produced?

Every large scheme needs consent, so local opposition can block a wind farm while a government target can push a nuclear station through.

Questions from this subtopic

Each one with the model answer underneath.

1
Which three kinds of factor decide what Britain's future energy mix will look like?
Model answer
Economic ones such as cost, political ones such as policy and security, and environmental ones such as emissions and damage to landscape.
2
How does cost decide which power stations get built?
Model answer
Investors and government back whichever source generates most cheaply across a station's lifetime, which is why wind and solar, now among the cheapest sources, have expanded fastest.
3
Why does the world price of gas matter to British energy decisions?
Model answer
A high or unstable price raises household bills and makes home-grown renewables and nuclear look better value by comparison.
4
What does energy security mean for a country like Britain?
Model answer
Having a supply that is reliable and affordable and cannot easily be cut off by another country's decisions or by conflict abroad.
5
How can a war overseas change British energy policy?
Model answer
Interrupted supplies and soaring prices push government to generate more at home, to store more gas and to speed up renewable building.
6
How does the planning system shape where energy is produced?
Model answer
Every large scheme needs consent, so local opposition can block a wind farm while a government target can push a nuclear station through.
