The world’s largest offshore wind farm Hornsea 2 in the UK has 165 wind turbines.

A single rotation of a wind turbine takes 6 seconds and generates energy to power a home for a day. How many homes can the Hornsea 2 wind farm power in an hour of operation?

1,650 homes

9,900 homes

99,000 homes

ANSWER 3

1 hours = 3600 seconds

A wind turbine rotates [3600/6=600] times in an hour.

A wind turbine generates energy to power 600 homes in an hour.

There are 165 wind turbines in the Hornsea 2 wind farm, so the wind farm can generate energy to power [600 x 165 = 99,000] homes in an hour.
