The production and consumption of electricity are most commonly measured in kilowatt -hours (kWh). A kilowatt -hour is one kilowatt (1,000 watts) of electricity produced or consumed for one hour. A 10 -kW wind turbine can generate about 10,000 kWh annually (enough to power a typical household) at a site such as Spirit Lake, Iowa, with wind speeds averaging 12 miles per hour. The 250 -kW turbine installed at the elementary school in Spirit Lake provides about of electricity annually.
A) 250 kWh
B) 250 mWh
C) 2,500 kWh
D) 25,000 kWh

Quizplus · Accepted Answer

Given that a 10-kW turbine generates about 10,000 kWh annually, a 250-kW turbine, which is 25 times more powerful, would generate 25 times more electricity, resulting in 250,000 kWh annually.
