Companies working in the offshore wind sector as well as the wave and tidal energy industries exported goods and services to 44 countries in 2017 according to a RenewableUK study.
The R-UK report found 43 British companies signed 445 deals worth up to £7.5m each to work on 434 projects all over the world.
The contracts ranged from exporting small onshore wind turbines to providing 80-metre blades and cables for offshore projects.
R-UK chief executive Hugh McNeal said: “It’s great to see UK companies are winning multi-million pound contracts to work on wind and marine energy projects on all seven continents.
“We are an outward-looking sector, increasingly export-led, securing new deals worldwide.”
Minister of State for the Department for International Trade Baroness Fairhead said: “This report demonstrates that there is a clear demand for innovative UK energy technology across the world as the renewable energy sector continues to grow.”
The report - Export Nation - is being released ahead of Global Offshore Wind 2018, which opens in Manchester tomorrow.
