Explaining the decline of US wind output power density
To study this effect, we present a decomposition of US wind power generation data for the period 2001–2021 and examine how changes in input power density and system efficiency affected
Wind Output Falls to a 33-Month Low in July
Despite the installation of more and more wind turbines, wind production declined in July to a 33-month low. Wind production also declined in 2023 from the year before despite 7 gigawatts of
Why Does Wind Turbine Efficiency Degrade over Time?
Wind turbine efficiency degrades over time primarily due to wear on blades and components, environmental exposure, and control system aging reducing energy capture.
System efficiency of US wind power generation is declining
The reason is that the efficiency of converting power in the wind into electricity is not uniform over the whole range of wind speeds for wind turbines. For low wind speeds, this conversion efficiency is low,
Wind generation declined in 2023 for the first time since the 1990s
Last year, the average utilization rate, or capacity factor, of the wind turbine fleet fell to an eight-year low of 33.5% (compared with 35.9% in 2022, the all-time high). The 2023 decline in wind
DOE Releases New Reports Highlighting Record Growth, Declining Costs
The U.S. Department of Energy today released three reports showing record growth in land-based wind energy, significant expansion of the pipeline for offshore wind projects, and
Report – The hidden cost of wind: why turbine degradation deserves
Drawing on over 11,000 turbine-months of operational data from 215 turbines across 37 wind farms in Western Europe, this study cuts through industry assumptions and paints a clearer
How Efficient Are Wind Turbines in 2025? Explained
This guide provides a data-driven comparison of wind turbine efficiency against solar power and fossil fuels, exploring cost-effectiveness, capacity factors, and technological innovations shaping the future
Data-Driven Assessment of Wind Turbine Performance
On these grounds, the present work is devoted to test case studies for the evaluation and the interpretation of wind turbine performance decline with age.
The power of wind: The global wind energy industry''s successes and
Using an Original Institutional Economics (OIE) approach to examine real world developments, we argue that the global wind energy industry is increasingly volatile and
