Vestas Wind Systems, Gamesa Corp Tecnologica and Nordex, Europe's three publicly traded wind-turbine makers, all doubled in value in 2015 after record industry installations for the year.

Turbine makers are benefiting from surging demand for clean energy. Global wind-power installations are expected to reach 63.7 gigawatts this year, up 30 per cent from 2014, the previous record, according to Bloomberg New Energy Finance.

New capacity next year will be comparable, with Brazil, the United States and India posting the biggest gains in terms of megawatts added, offsetting declines in China, Germany and Poland.

"We're expecting 2016 to be an equally good year," said David Hostert, a wind analyst in London for New Energy Finance. – (Bloomberg)
