(Reuters) – The world will have enough wind turbines to generate more than 300 gigawatts of power – the equivalent of 114 nuclear power plants – by the end of the year, industry figures show.

As BrazilChinaMexico and South Africa add turbines, the figure represents modest growth compared with a year ago, when the overall total capacity was just over 280 gigawatts.

"Worldwide installed wind power will exceed 300 gigawatts of power capacity this year," Peter Sennekamp, media officer for the European Wind Energy Association (EWEA), said, citing figures compiled by EWEA and the Global Wind Energy Council.

Europe, which has led the world on wind, still represents around a third of all capacity, with more than 100 gigawatts, but its growth has been stalled by uncertainty as financial crisis has meant abrupt changes to subsidy regimes.

The European Commission, the European Union's executive, has supported the idea of harmonization of subsidies across the European Union and said it will publish guidelines before the summer break in August.

However, EU authorities cannot dictate to member states what kind of energy sources they use and how they are financed.
