A survey of energy experts predicts the cost of electricity generated by wind should plunge by 24 to 30 percent by the year 2030, and even further by the middle of the century.
One key reason? New wind projects are about to get even more massive, in both the offshore and onshore sectors. As taller turbines access stronger winds, and as rotors increase in diameter, it becomes possible to generate ever more electricity from a single turbine.
“Our experts clearly anticipate a significant potential for further cost reductions, both onshore and offshore,” said Ryan Wiser of Lawrence Berkeley National Laboratory, who conducted the study with colleagues from other institutions, including the National Renewable Energy Laboratory, the University of Massachusetts, Amherst, and an International Energy Agency task force on wind energy.
The fact that onshore wind costs are expected to decline was suprising, Wiser said. “There are some questions …. about what additional technology advancement possibilities might still exist.”
