Declining costs for utility-scale wind turbines are one factor that has helped drive the price of wind-generated electricity to its lowest point ever, the Lawrence Berkeley National Laboratory says in its annual Wind Technologies Report.
The report said that utility purchasers were offered an average price of less than 2.5 cents per kilowatt-hour in contract negotiations in 2014, a year in which wind installations reached 4.9 gigawatts of new capacity. New projects were valued at a total of $8.3 billion.
