Lynsey Jones, senior climate programme manager at the Conservative Environment Network, said expanding renewable energy is the "best way to improve the UK’s energy security".
She said: "In particular, we should be taking advantage of our naturally windy seas. We’ve already established ourselves as a world leader in fixed offshore wind, and now the Government should turn its attention to floating projects.
"The supply chain for these developments is yet to be fully established. The Government needs to seize the opportunity to mature this new industry and reassure renewables firms that Britain is still the place to direct investment.
"The Chancellor should use the upcoming Autumn Statement to expand support for manufacturing in ports where they can make the most of favourable freeport tax conditions.
"He should also make capital expensing permanent, which would improve the business case for new wind farms."
