Bigger and bigger wind turbines.

Whereas 82 percent of offshore turbines ordered between 2001 and 2005 were under 3 megawatts, today there are no machines of that size on order.

Instead, 71 percent of orders are for products 5 megawatts or greater, and 16 percent are for turbines of 8 megawatts or greater. “Despite long project cycles and R&D timelines, commercial demand continues to favor the largest turbines,” says the report. “The next generation of 12-megawatt-plus turbines will gain market share within the next five years.”
