The Past and Future Cost of Wind Energy

The Past and Future Cost of Wind Energy

Date: 5/31/2012

IEA Wind (Task 26) published a new report, The Past and Future Cost of Wind Energy, that presents key global historical trends in the cost of wind energy, while also summarizing forecasts for the future cost of wind energy. Contributors to the report include staff at the National Renewable Energy Laboratory and Lawrence Berkeley National Laboratory, as well as European participants in the IEA Wind's "The Cost of Wind Energy" task.

Over the past 30 years, wind power has become a mainstream source of electricity generation. However, the future of wind power will depend a great deal on the ability of the industry to continue to achieve cost of energy reductions. This summary report reviews the methods used to estimate long-term cost trajectories and summarizes the range of costs projected for onshore wind energy across an array of forward-looking studies and scenarios. It also highlights high-level market variables that have influenced wind energy costs in the past and are expected to do so into the future. Coverage is primarily focused on the United States and Europe.
