The opposition Conservative Party has released a report arguing that the UK’s net-zero by 2050 target increases electricity prices and should be abandoned in favor of prioritizing cheaper power through greater reliance on gas and nuclear energy. The report, produced by centre-right thinktank Onward and based on modeling by advisory firm Transira Energy, claims this approach would save over £320bn and make electrification of transport and heating more attractive to consumers and businesses.
However, multiple energy experts have identified significant flaws in the analysis that undermine the report’s central claims. The proposed alternative scenario would actually generate an additional 524 million tonnes of carbon dioxide emissions between 2030 and 2050—equivalent to South Africa’s annual emissions—contradicting Conservative assertions that cheaper electricity would drive faster emissions reductions. The increase stems from expanded unabated gas-fired power capacity in the model.
Critics point out that the alternative pathway would produce slower adoption of electric vehicles and heat pumps despite lower electricity costs, because it assumes removal of government subsidies and mandates such as the boiler upgrade scheme and the 2030 ban on new petrol and diesel vehicle sales. Overall electricity consumption would be 7% lower than under current policies. The report also fails to account for substantial costs, including an estimated £65-95bn in additional petrol and diesel fuel expenditure over two decades to replace missing electric vehicles, and costs associated with accelerated data centre grid connections.
Energy experts further note that the analysis does not demonstrate the electricity-to-gas price ratio would fall sufficiently by 2050 to naturally drive consumer adoption of heat pumps without continued government support. According to analysts at the Energy and Climate Intelligence Unit, the modelling indicates the price gap would actually widen initially before narrowing only marginally by mid-century, contradicting claims that cheaper electricity alone would encourage electrification without policy incentives.
