Influence And Impact

The publication of this 2021 Annual Report marks the end of year two of GWO’s three-year “Safety Without Borders” strategy. At the time of its launch, two years of pandemic seemed inconceivable, but today individuals and states are still struggling. However closer to home within the wind sector a new (nearly) normal has prevailed ensuring not only that the lights never went out, they now burn even brighter.

The 2020 strategy included the deliberately stretching strategic goal of building a GWO trained  workforce to more than 200,000 people. The interim goal for 2021 was set to reach a GWO Trained Workforce of 150,000 people by 31st December 2021. During 2021 the pattern of the 21% growth in trained workforce over 2020 was impressive, and increasing at a high rate with a new total of over 122,500 individuals.

The GWO Trained Workforce

The GWO Trained Workforce is a number representing course participants holding at least one valid training record in GWO’s WINDA database. At the end of 2021, the GWO Trained Workforce was 122,573, who hold between them a total of 557,462 valid GWO training records. Among those valid records, 85% have an expiration date (usually 2 years) and will need to be refreshed within the next 24 months.

GWO also tracks the increase in the number of participants trained over time. Between 2020 and 2021 this rose from 61,318 to 80,489 in 2021 an increase of 31% . During the same years these participants completed 225,347 training records rising to 316, 833 , an increase of 41% year on year.

The countries with the largest proportions of total GWO Trained Workforce are: United Kingdom (17,016 participants with at least one valid record), Spain (13,188), Germany (12,193), Denmark (11,424), United States of America (8,134), and Brazil (7,139).  

In 2021, GWO saw a return to the seasonal profile of safety training seen in 2019 and earlier with a pronounced peak in March related to the milder weather prevalent in the northern hemisphere and the burst of onsite construction activity during the following six months.
