The UK’s Climate Change Committee (CCC) has delivered a stark message: Scotland’s renewable energy capacity needs a massive boost to meet its carbon budgets and climate targets. The watchdog recommends that Scotland grow its onshore and offshore wind plus solar power from 15GW in 2023 to 49GW by 2035—and then to 66GW by 2045.
A Huge Leap in Renewable Power Is on the Horizon
This increase isn’t just a number on paper. It’s a monumental jump that means almost tripling current renewable energy output within the next decade. The CCC projects this expansion would cover 98% of Scotland’s electricity generation by 2035. That’s a near-complete transformation of the country’s power supply.
The demand for electricity is expected to rise both within Scotland and across Great Britain. To meet that, Scotland will need to harness more wind and solar energy than ever before.
The CCC’s advice comes as part of its first set of recommendations on Scotland’s four carbon budgets, which run from 2026 to 2045. These budgets represent legally binding limits on greenhouse gas emissions. The Scottish Government asked for this advice recently, following the example of other UK administrations like Westminster, Northern Ireland, and Wales, which have all used the CCC’s models.
Calls for Policy Changes to Lower Energy Costs
One significant point the CCC highlights is the impact of policy costs and levies added to electricity bills. They argue that these charges make electricity more expensive than necessary, which in turn slows down Scotland’s ability to decarbonise swiftly.
The CCC is urging the UK government to remove these extra costs, noting that cooperation between the Scottish Government and Whitehall is crucial. Without this, Scotland’s ambitious renewable goals could face serious roadblocks.
Industry Voices Push for Urgent Action on Heat and Networks
Morag Watson, director of onshore at Scottish Renewables, reacted strongly to the CCC’s recommendations. She stressed that achieving Scotland’s climate ambitions hinges on fast-tracking renewable energy projects, upgrading electricity networks, and deploying clean heat solutions.
Watson said the upcoming Heat in Buildings Bill is a pivotal moment. She called on the Scottish Government to provide a clear and practical strategy for decarbonising heat, especially emphasizing affordable heat networks.
She pointed out that funding schemes must be straightforward for both consumers and suppliers. “If we don’t make it easy to access support,” she said, “we’ll struggle to meet future electricity demand and miss out on the benefits that clean power can bring.”
Unlocking Scotland’s Renewable Potential Means More Than Just Green Energy
The push to boost renewable energy isn’t just about fighting climate change. It’s also about tackling fuel poverty, securing energy supplies, and unlocking new economic opportunities for Scotland.
Morag Watson highlighted that expanding clean power could spur long-term prosperity by creating jobs and reducing reliance on fossil fuels. She urged ministers to act decisively and make the ambitious path to decarbonisation a reality.
The Road Ahead: What Scotland Needs to Do
-
Triple renewable capacity from 15GW to 49GW by 2035
-
Expand further to 66GW by 2045
-
Remove levies from electricity bills to lower costs
-
Implement effective heat decarbonisation strategies
-
Upgrade electricity network infrastructure
-
Streamline funding schemes for consumers and suppliers
| Year | Renewable Capacity Target (GW) | % of Electricity from Renewables |
|---|---|---|
| 2023 | 15 | — |
| 2035 | 49 | 98% |
| 2045 | 66 | — |
The clock is ticking, and the CCC’s warnings are clear: Scotland’s climate goals require bold steps in renewable energy expansion and policy reform.
