The opposition Conservatives have released a report arguing that prioritizing cheap electricity over net-zero climate targets would benefit both the economy and environment by encouraging adoption of electric vehicles and heat pumps. The report, produced by the centre-right thinktank Onward and based on modeling by Transira Energy, suggests the UK could save over £320bn by scrapping current net-zero policies. However, a detailed factcheck by Carbon Brief working with energy experts identifies significant issues with the analysis.
Central to the Conservative pitch is the claim that lower electricity prices would naturally encourage electrification of transport and heating, ultimately reducing emissions. Yet the report’s own modeling contradicts this premise. The alternative policy scenario it proposes would result in an additional 524 million tonnes of carbon dioxide emissions by 2050—equivalent to South Africa’s annual emissions—primarily due to increased reliance on unabated gas-fired power generation. Furthermore, the alternative scenario actually shows slower adoption of heat pumps and electric vehicles compared to current policy pathways, despite lower electricity costs, because supportive government measures such as subsidies and vehicle sales bans would be removed.
Experts point to numerous questionable assumptions underlying the analysis. The modeling relies on the premise that gas prices will remain low and stable, while suggesting renewables will be costlier than nuclear and gas—conclusions experts say would be reversed with more credible assumptions. Imperial College London’s Iain Staffell describes the modeling as having “more holes than a Swiss cheese.” Additionally, the report fails to account for significant costs, including an estimated £65-95bn in fuel expenditures for vehicles that would continue using petrol and diesel rather than switching to electric alternatives.
Other technical issues include incomplete accounting for the costs of prioritizing data centre grid connections and insufficient analysis of whether the proposed electricity-to-gas price ratio would sufficiently decline to drive consumer behavior change without government incentives. Energy experts argue the report fundamentally overlooks feedback effects where lower electricity and electrification technology costs would be expected to increase adoption rates independent of explicit policy support.
