Britons generally support expanding the use of renewable energy sources but express doubts about their effectiveness in reducing energy bills, according to a recent survey.

The British government is advancing plans to increase nuclear power capacity, with the goal of it supplying 25% of the nation's electricity by 2050. This ambition may find some public favor, as a YouGov survey commissioned by cable supplier Eland Cables revealed that 21% of Britons prefer nuclear energy over solar power (19%) and offshore wind (18%).

Despite this support for green energy, a notable divide exists between public approval of these initiatives and confidence in their practical outcomes. Half of those surveyed believe green energy is unlikely to decrease energy bills within the next decade, and a similar proportion question whether it can meet Britain's future energy demands.

The government has been investing in the transition to net-zero energy with the aim of enhancing Britain's energy security and mitigating exposure to volatile wholesale prices, particularly during periods of global conflict. The ongoing conflict in Iran has contributed to another increase in energy bills, with the energy price cap rising by 4% in October. Forecasters at Cornwall Insight anticipate a further 9% increase in January.

While the Labour party plans to boost investment in green energy, 46% of households remain unconvinced about its potential to provide energy security, and 22% fear it will negatively impact prices further. The anticipated rise in prices this winter is expected to offset the proposed VAT cut on energy bills scheduled for October. Energy supplier EDF has warned that bills could remain 'stubbornly high' until the end of the decade.

Public enthusiasm wanes even further for additional investment in North Sea oil and gas. As the future of the Jackdaw gas field and Rosebank oilfield in the region awaits a decision, only 29% of respondents support new drilling licenses.

Although the majority of Britons favor wind and solar projects, support diminishes when these projects are located nearer to their communities, raising questions about local benefits. Homeowners, in particular, appear more concerned, with 55% believing more green energy projects would detract from local landscapes and green spaces, compared to 43% of renters.

"These findings suggest the public is no longer asking whether renewable energy should be deployed. The bigger question is now whether the benefits are being felt yet," stated Jean-Sébastien Pelland, executive director at Eland Cables. He added that while support remains high, significant uncertainty persists regarding energy costs, security of supply, and future demand. "That tells us the conversation is becoming less about ambition and more about delivery…. It's no longer enough to measure success by megawatts installed."
