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
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.
