In today’s energy debates, certain assertions tend to echo most strongly—not because they’re accurate, but because they’re repeated.
One version says renewables are now “nine times cheaper,” that bills will fall by £300, and anyone challenging those claims is labeled a “climate vandal.” This rhetorical pattern—claim, repetition, deflection of critique—serves as a paradigm reinforcement engine. It’s a tactic now operative across the UK’s Department for Energy Security and Net Zero (DESNZ), the Climate Change Committee, and regulators like Ofgem and the National Grid.
These narratives, however appealing, stumble hard when weighed against data. The UK currently has some of the highest electricity prices for industrial users in the developed world—averaging £258/MWh in 2023, higher than counterparts in the US, Germany, and China.
That reality undercuts any sweeping claim that renewables alone have made energy broadly “cheap.” Worse, government policies have locked in long-term contracts (like 20-year Contracts for Difference) that cement these elevated costs well into the 2040s.
To reconcile lofty promises with structural constraints, proponents often shift the conversation toward the future: “Yes, prices are high today—but tomorrow, things will change.” Yet that logic ignores the path dependency built by current decisions. Investments in remote offshore wind farms—especially in Scotland—frequently encounter curtailment rates as high as 40%, undermining grid value even when output is available. The mismatch between location and demand load drives up reliance on transmission infrastructure and backup gas generation, pulling up system costs for all consumers.
Nor is it defensible to argue that wind and solar must determine power-sector economics simply because their marginal cost is near zero. That framing erases the cost of integrating intermittency—storage, grid expansion, balancing mechanisms—and ignores the geographical and meteorological limits of wind and solar in regions like Britain. In contrast, gas plants regularly set wholesale electricity prices—even when they run for only a small share of hours—because of the marginal pricing structure. That means even when 99% of demand is met by renewables, the last 1% is often set by expensive gas-powered marginal units.
Critics argue policy design and market architecture have played a deeper role in inflating consumer costs. Levies meant to subsidize renewables or capacity markets are fed into consumer bills. Network costs, carbon levies, balancing charges, and grid reinforcement all land on final tariffs. As reported by the International Energy Agency, UK industrial electricity costs are roughly four times higher than those in the US and substantially above many EU peers.
To shift this trajectory requires rejecting the myth that renewables alone guarantee low energy costs. Policymakers must bring the full system into view: generation, storage, transmission, pricing design, and long-term contracts. Local supply chains, modular nuclear, flexible and dispatchable resources, and demand-side solutions all need recalibrated roles. False promises have long shaped public expectations; credible modeling, transparent cost accounting, and policy coherence are required if a genuine, affordable transition is to be engineered.
