Fig. 8: Comparison of 2020 survey results with other contemporaneous LCOE forecasts.

From: Expert elicitation survey predicts 37% to 49% declines in wind energy costs by 2050

Fig. 8

a,b, Depicts the median of expert responses for LCOE in the median, low and high scenarios for onshore (a) and offshore (b) wind. The shaded areas span the 2020 survey results. Survey results are compared with a range of other LCOE forecasts41,44,45,46,47,48,49. Note that such comparisons are imperfect; for example, some forecasts include offshore transmission-infrastructure costs in LCOE whereas the 2020 survey results exclude those costs. Where possible we apply a geographic weighting across regions to approximate the distribution of the survey respondents. NREL provides a range of cost projections in its Annual Technology Baseline (ATB). The IEA offers two projections in its World Energy Outlook (WEO).
