More than £81 billion worth of renewable energy projects are proposed by 2025, representing nearly half of all infrastructure spending in the UK, new figures reveal.

The Scottish share is £16.4bn or 20 per cent of the headline figure, but the industry in Scotland is warning sustained political support is needed to reassure the investors who can make it happen.

Barbour ABI, a specialist provider of construction intelligence services which advises the Office for National Statistics (ONS), has released new data revealing a total of 405 renewable energy projects in the pipeline. They are worth a combined total of £81bn which now account for approximately 47 per cent of proposed UK infrastructure projects.
