Answer:
the number of houses ≈ 8.25 million houses
Explanation:
Given that:
A typical house in the United States uses about 10,900 kWh,
1 TWh (terawatt-hour) =1×10^6 GWh (gigawatt-hour) =1×10^9kWh (kilowatt-hour)
The three Gorges Dam in China produces about 90TWh of electricity each year. If it was to to be built in the United states, the number of houses such a plant would be able to provide the electricity for in a year is given as:
Number of houses = Amount of electricity produced in a year / amount of electricity used by each house.
Number of houses = 90 TWh / 10,900 kWh = 90 × 10⁹ kWh / 10,900 kWh = 8256881
Therefore the number of houses ≈ 8.25 million houses
