Wind,solar And Geothermal

Question 1

Wind power

Answer 1

Each turbine has a generator inside it

There’s no pollution

Turbines stop when the wind stops or if the wind is too strong

Blocks the view (so they have a big effect on scenery)

On average, wind turbines produce energy 70-85% of the time

Question 2

Solar cells

Answer 2

They generate energy directly from sunlight

Solar power is often used in remote places

There’s no pollution

In sunny countries solar power is a very reliable source of energy

Like wind you can’t increase the power output

Initial costs are high but after that the energy’s free

Question 3

Geothermal power

Answer 3

Based in volcanic areas or where hot rocks are

Does little damage to the world

This is completely free

Geothermal power can be used to generate electricity or to heat buildings directly
