Why is sunny and windy weather good for the environment?
More energy is produced from renewables than from fossil fuels in the UK
Tidal power is at a maximum
The wind blows the pollution from coal power stations out to sea where it is harmless.
Hydroelectric power has ts maximum efficiency in this weather

In the morning as people wake up
In the middle of the day, when most people are at work
In the evening when people make cups of tea/coffee
At night, when we charge our phones
How can energy be stored when supply is greater than demand. Select two answers.
By creating nuclear fuel
By pumping water to a high level reservoir
By storing it in an electric car's batteries
By keeping electricity flowing around a circuit
