Offshore wind turbines are about to become higher than the Eiffel Tower, allowing the industry to supply subsidy-free clean power to the grid on a massive scale for the first time.

Manufacturers led by Siemens AG are working to almost double the capacity of the current range of turbines, which already have wing spans that surpass those of the largest jumbo jets. The expectation those machines will be on the market by 2025 was at the heart of contracts won by German and Danish developers last week to supply electricity from offshore wind farms at market prices by 2025.
