Offshore wind power in Japan will be able to replace more than half of the nation’s generation capacity forecast to retire by midcentury, according to an industry group promoting its developments.

The capacity of Japan’s offshore wind farms could total 90 gigawatts by 2050, equivalent to 60 percent of the fossil fuel and nuclear facilities expected to be closed by that time according to Shigehito Nakamura, a managing director of the Japan Wind Power Association.

Japan is seeking cleaner ways to feed its energy-hungry but resource-scarce economy, the world’s biggest after the U.S. and China. It’s reliance on fossil fuels faces resistance over climate change concerns, while its massive nuclear fleet is at risk of being abandoned due to widespread opposition to the technology following the 2011 Fukushima disaster.
