Experts Predict 50% Lower Wind Costs Than They Did in 2015
Study shows expected cost declines of 37%–49% by 2050
Technology and commercial advancements are expected to continue to drive down the cost of wind energy, according to a survey of the world’s foremost wind power experts led by Lawrence Berkeley National Laboratory (Berkeley Lab). Experts anticipate cost reductions of 17%–35% by 2035 and 37%–49% by 2050 under a median or best-guess scenario, driven by bigger and more efficient wind turbines, lower capital and operating costs, and other advancements. The findings are described in an article in Nature Energy, with further details on the Berkeley Lab website.
Following a similar effort in 2015, the study summarizes a global survey of 140 wind energy experts. It uncovers insights on the possible magnitude of and drivers for cost reductions, anticipated technology trends, and grid-system value-enhancement measures. It focuses on three wind applications: onshore (land-based), fixed-bottom offshore, and floating offshore.
Wind Repowering Helps Set the Stage for Energy Transition
Research findings highlight motivations behind wind power’s second act
Wind energy is already a major contributor to the U.S. energy system (9.2% of all electricity in 2020) and is expected to become even more so in the future. Boosted by advancing technology, economies of scale, and plummeting costs, the U.S. industry had an exceptional year in 2020, with wind power capacity additions of 14.2 gigawatts (GW).
Although new wind power plant plans and installations dominate headlines, wind repowering—the combined activity of dismantling or refurbishing existing wind turbines and commissioning new ones—also plays an important role in the industry. By modernizing the existing wind fleet, repowering sets the stage for future wind industry funding and helps maximize wind energy use in the coming energy transition.
Recognizing this potential, several members from the International Energy Agency Wind (IEA Wind) Technology Collaboration Programme Task 26—led by NREL, with funding from WETO—published an article in Nature Energy that explores the drivers influencing onshore wind energy repowering decisions.
