Offshore Wind Set to Quadruple by 2035, Powering 420 Million

Offshore wind energy is experiencing a growth surge that could transform how the world powers itself while protecting against future energy crises.

Last year alone, more than 9 GW of new offshore wind capacity started generating electricity worldwide, enough to power over 10 million homes. That brought the global total to 92.5 GW, making offshore wind one of the fastest-growing energy sources on the planet.

The numbers get even more exciting from here. With over 50 GW of offshore wind projects already under construction, annual installations are expected to double this year, triple by 2031, and surpass 50 GW per year by 2035.

The Global Wind Energy Council predicts offshore wind will grow at 24% annually through 2030. Over the next decade, 327 GW of new capacity will be added, quadrupling total capacity to 420 GW by 2035.

"Built at scale, offshore wind is a unique strategic asset and one of the best available utility-scale renewable power sources for a clean and secure power system," said Rebecca Williams, Deputy CEO of GWEC. She points out that in less than five years, the world has faced two major crises caused by reliance on imported fuels.

China led installations for the eighth straight year, adding 6.6 GW in 2025. Europe added nearly 2 GW across the UK, Germany, and France, showing growing momentum across multiple continents.

Countries are recognizing offshore wind as more than a climate solution. The UK, European Union, Turkey, China, the Philippines, Vietnam, South Korea, and Japan are all accelerating their offshore wind programs to strengthen energy security and reduce dependence on imported fuels.

The Ripple Effect

The benefits extend far beyond cleaner electricity. Building offshore wind capacity creates jobs in manufacturing, construction, and maintenance while developing domestic supply chains that keep investment and expertise local.

As countries electrify their economies, offshore wind provides predictable, reliable power generation that can anchor entire energy systems. Instead of sending money overseas for fuel, nations can invest in homegrown infrastructure that delivers energy security for decades.

The technology is proven, the economics are improving, and governments are starting to treat offshore wind as critical national infrastructure. Streamlined permitting, better grid planning, and long-term procurement frameworks are helping projects move from planning to reality faster.

Within a decade, hundreds of millions of homes worldwide will be powered by wind turbines standing tall along coastlines, turning ocean breezes into energy independence.
