Opinion: Why the UK Must Accelerate Investment in Renewable Energy Infrastructure Now

The United Kingdom stands at a crossroads in its energy transition. We have the best offshore wind resources in Europe, world-class tidal energy potential, and growing solar capacity. Yet we are systematically failing to capitalise on these advantages through underinvestment in the infrastructure needed to connect, store, and distribute renewable power.

The recent extreme heatwave, which pushed temperatures to a record 36.4C, served as a stark reminder that climate change is accelerating. Renewable energy is not just an environmental imperative — it is a national security and economic necessity.

The single biggest obstacle to the UK's renewable energy transition is not a lack of wind or sun, but a lack of grid capacity. Projects representing over 100GW of renewable generation are stuck in connection queues, some waiting up to ten years.

Even when renewable generation is abundant, we lack the storage capacity to capture excess power. The UK currently has approximately 3GW of battery storage capacity, but analysts estimate we will need at least 30GW by 2035 to maintain grid stability.

The UK has been a global leader in offshore wind, but that lead is slipping. Denmark, Germany, and the Netherlands are accelerating their ambitions, and China installs more offshore wind in a single year than the UK has built in its entire history.

The economic argument is overwhelming. The UK spent approximately £40 billion on energy imports in 2025. Every megawatt of renewable capacity installed reduces that exposure and keeps money in the UK economy. The government must treat renewable energy infrastructure as the national priority it is.
