WASHINGTON (AP) American University says it has purchased wind-generated renewable energy credits equal to the school's annual electricity use.
The school announced the purchase on Tuesday. American says it is now the largest east coast school to purchase credits equal to 100 percent of its power use, about 53 million kilowatt hours per year.
American did not announce the cost of the purchase. But a credit for a megawatt hour of domestic power costs between $1.50 and $2, and American purchased 53,000 megawatt hours. That makes the purchase price between $79,00 and $106,000.
For the past two years, American has purchased credits equal to 25 percent of its power use.
Catholic University in Washington also buys renewable energy credits.
