Answer
(b)
Work Step by Step
The total electricity produced by the wind farm can be calculated as follows:
Total electricity = Number of turbines × Electricity per turbine × Capacity factor
Total electricity = $50$ turbines × $2$ MW per turbine × $0.2$ (capacity factor) = $20$ MW
Now, to find the number of homes supplied:
Total electricity required by homes = $1.25$ kW (per home) × Number of homes
Number of homes = Total electricity / Electricity per home
Number of homes = 20,000 kW / 1,250 kW (1.25 kW ≈ 1,250 kW) ≈ 16,000 homes.
The answer is (b).
