According to the U.S. Office of Energy Efficiency and Renewable Energy, the U.S. has 28 projects in progress and development totaling 23,735 MW of power. Those in the near term are primarily concentrated in the North Atlantic with others in various stages of evolution in the Great Lakes, the West Coast and Hawaii. In Europe, 17 new wind farms were constructed in 2017, including 560 new offshore wind turbines, producing a record 3,150 MW of additional capacity. This positive growth in the European offshore sector has been driven by falling costs alongside advancements and innovation in cost-out measures (calculating total cost in advance) achieved through a greater understanding of the key risks in off-shore wind tower construction, with larger projects leading to greater economies of scale and an oversupply in the wind turbine market. Offshore wind energy is projected to become Europe's fastest growing renewable source. The rise in offshore wind energy has spurred a similar growth in related protective coatings. Although the offshore wind industry is known to be generally conservative, its search for cost savings has encouraged coatings manufacturers to research and develop new and innovative materials that can be applied more quickly, and that offer optimal protection.
