IEA Wind Task 26: Wind Technology, Cost and Performance Trends in Denmark, Germany, Ireland, Norway, the European Union, and the United States: 2007 - 2012

Cost of Wind Energy is an international collaboration project that explores the past, present and future cost of wind energy. Participants in the project representing several countries with wind deployment have conducted an analysis of technology, cost and performance trends from 2007 to 2012. Statistical representation of technology characteristics such as project size, turbine size, rotor diameter, and hub height are presented. Similarly capital investment cost, average wind speed, and energy production statistics over this period are also presented for each of the participating countries. Based on this data, estimates of cost of energy in the participating countries are made using a common cash flow model. Each country also reports typical revenue streams and or policy mechanisms by which the wind plant cost is recovered.
