Wind vitality scientists at Cornell College have launched a brand new international wind atlas – a digital compendium crammed with documented excessive wind speeds for all elements of the world – to assist engineers choose the generators in any given area and speed up the event of sustainable vitality.
This wind atlas is the primary publicly obtainable, uniform and geospatially express (datasets tied to places) description of maximum wind speeds, in accordance with the analysis, “A International Evaluation of Excessive Wind Speeds For Wind Power Purposes,” printed on January 25, 2021, in Nature Power.
“Price-efficient enlargement of the wind-energy business is enabled by entry to this newly launched digital atlas of the acute wind circumstances below which wind generators will function at places around the globe,” mentioned Sara C. Pryor, professor within the Division of Earth and Atmospheric Sciences, who authored the paper with Rebecca J. Barthelmie, professor within the Sibley Faculty of Mechanical and Aerospace Engineering. Each are college fellows on the Cornell Atkinson Middle for Sustainability.
“This sort of info will guarantee the right number of wind generators for particular deployment,” Pryor mentioned, “and assist guarantee cost-efficient and reliable electrical energy era from these generators.”
Understanding excessive wind speeds is vital to turbine design for price effectiveness, correct turbine choice and structural integrity on any given web site, mentioned the researchers. Earlier than, in lots of places, excessive wind-load estimates on initiatives have been unsure because of restricted on-site measurements.
By the top of 2019, whole international wind turbine put in capability was greater than 651 gigawatts (GW), in accordance with the paper, because of 60 GW of just lately constructed capability – of which practically 90% was positioned onshore. “Thus, wind is now producing over 1,700 terawatt hours of electrical energy per 12 months or about 7.5% of the worldwide electrical energy provide,” Pryor mentioned.
Barthelmie and Pryor report that the USA carries 17% of the world’s present wind vitality put in capability, whereas Europe (31%) and China (36%) carry extra.
There are actually wind generators producing carbon-free electrical energy in additional than 90 nations, Pryor mentioned.
Improvement of analysis product was motivated by a necessity from the wind-energy business, Barthelmie mentioned. Quantifying excessive winds may be helpful in civil engineering purposes and in structural reliability analyses for tall buildings and transportation programs – together with long-span bridges – in addition to for electrical energy era and distribution.
Stated Pryor: “Additional cost-efficient enlargement of the wind-energy business will probably be enabled by entry to this newly launched digital atlas.”

Funding for this analysis was supplied by the U.S. Division of Power (Grants DE-SC0016438 and DE-SC0016605) and was carried out on the Nationwide Science Basis’s Excessive Science and Engineering Discovery Atmosphere (XSEDE) computational assets (Award: TG-ATM170024).
