Rance Tidal Power Station is in France on the estuary of the Rance River. From the time it was built in 1966, until recently it was the world’s largest tidal station. It produces power at a rate of 240 MW and generates 600 GWh yearly.
Nantes is the largest city in the region and has a population of about 300,000 people. The average person there uses about 7000 kWh of electricity, annually.
If all of Rance’s power went to the city of Nantes, what percent of Nantes power would come from the tidal station?
