The ongoing Iran war has led to a surge in petrol and diesel prices, sparking concerns about fuel rationing across Europe and calls for Britain to increase North Sea oil and gas production. However, experts suggest that a more effective solution lies in promoting electric vehicles (EVs). According to analysis by Mandala Partners, if the UK had the same proportion of electric cars as Norway, its fuel reserve could increase by seven days. Currently, the UK has about three weeks' worth of car fuel in reserve. Norway leads the world with nearly 32% of its cars being fully electric, compared to 5.4% in the UK. Even with the existing number of electric and hybrid cars on British roads, they are already saving about two days' worth of fuel. This is particularly significant given that Shell's chief executive, Wael Sawan, has warned that Europe could face fuel shortages as early as April if the Strait of Hormuz remains closed. The potential impact of EVs goes beyond just reducing petrol and diesel consumption. Every electric car charged from the grid rather than the pump extends the country's fuel reserves. Moreover, with the right technology, EVs could become an active buffer against future energy shocks by storing and resharing energy. Vehicle-to-grid technology, which allows EVs to send energy back into the power grid, could make a significant difference in an energy supply crisis. An electric car usually holds about 40 kilowatt-hours of power, enough for an average UK home for several days. This technology could enable millions of car batteries to supply power to the grid when demand spikes. Despite these benefits, the adoption of EVs and vehicle-to-grid technology faces challenges. Tax policy is a significant barrier, as EV owners pay tax on electricity when filling their car battery and again when selling it back to the grid. Additionally, the hardware for two-way charging is not yet widely available, although many electric cars are already capable of it. The energy regulator Ofgem has suggested that if half of the expected 11m EVs on UK roads by 2030 were capable of two-way charging, they could send 16 gigawatts of power back to the grid each day, almost half the output of Britain's gas-power station fleet.

The UK's green energy landscape is experiencing a significant shift as Jürgen Maier, the boss of GB Energy, joins other prominent renewable energy leaders in advocating for increased North Sea oil and gas production. This move comes as the UK government faces mounting pressure to address an impending energy cost crisis. Maier, in a social media post on LinkedIn, emphasized that while more North Sea oil and gas may not directly reduce energy costs, which have surged due to escalating tensions in the Middle East, it could bring substantial economic benefits, including more jobs and higher tax revenues. He described himself as “a supporter” of a well-managed energy transition that includes “all energy,” later clarifying in a separate post that he fully supports the government’s ban on new oil and gasfield exploration licences. Maier suggested that utilizing existing fields and tiebacks—allowing new deposits to be extracted from existing infrastructure—aligns with an 'All Energy' approach. This strategy, he argues, would give supply chain companies sufficient time to transition while renewables remain the long-term goal. The comments from Maier follow similar endorsements from other green energy leaders, such as Greg Jackson, the Octopus Energy boss, and Tara Singh, the new chief executive of RenewableUK. Jackson, who sits on the Cabinet Office board, told the Daily Telegraph that the UK needs more “sovereign energy,” which requires practical decisions, including leveraging North Sea resources. Singh argued that Britain should produce more energy “of every kind” and called for taking energy out of the culture wars. Despite these calls, Energy Secretary Ed Miliband has ruled out new licences for the North Sea, though decisions on the Rosebank and Jackdaw fields, which were licensed under the previous government, are still pending. Industry sources expect these fields to be approved soon, potentially beginning production by the end of the year, which could provoke backlash from green groups. The government recently dismissed warnings from Offshore Energies UK that failing to produce more North Sea oil and gas would increase the UK's reliance on imports amid rising global instability. A government spokesperson stated that new licences would not enhance energy security or reduce bills, highlighting that oil and gas prices are set internationally. A Great British Energy spokesperson reiterated the company's focus on driving the clean energy transition to deliver a more secure and independent energy system. They emphasized that oil and gas will remain part of the energy mix for decades, and preserving the skills of oil and gas workers is crucial for a clean energy future.

The UK government has rejected a call from the Offshore Energies UK trade body to boost North Sea oil and gas production, despite warnings that the UK will become increasingly reliant on imports at a time of rising global instability.The industry group has urged the government to take action to slow the decline of the North Sea as a provider of energy, citing concerns that consumers will be left more exposed to global volatility and higher emissions if domestic production is not increased.The warning comes as the war in the Middle East has triggered the biggest oil and gas supply shock in the history of the market, causing UK gas prices to more than double in under a month.A government spokesperson said that issuing new licences to explore new fields cannot guarantee energy security and will not reduce bills, adding that the only way to truly protect against price spikes is to get off the rollercoaster of fossil fuel markets.The decline of the North Sea oil and gas basin means that the UK's reliance on gas imports is likely to increase sharply from about 14% last year to more than a quarter of its gas supply by 2030, and almost half by 2035.David Whitehouse, the chief executive of Offshore Energies UK, argued that energy security means backing homegrown oil and gas alongside renewables, and that a stable new tax regime for the industry is essential to reduce reliance on volatile imports and protect skilled jobs.
