The wind energy sector is growing quickly as a result of the EU 2020 Strategy objectives for climate and energy policy. However, it brings with it many occupational safety and health (OSH) challenges as many aspects of onshore and offshore wind turbines are unique, and so are the working environments in which they are found. Being a relatively young industry, specific issues such as skills shortages and a lack of consistent procedures and standards also have an impact on OSH. This report introduces the wind energy sector and examines how its specific issues impact on OSH. It looks at the particular risks faced by workers during the various stages of the wind turbine life cycle, both onshore and offshore, and outlines the challenges ahead for the industry.
