National Gas announced that the United Kingdom will have enough gas to satisfy summer demand despite recent tensions in the Strait of Hormuz. The network, which runs the country’s gas pipelines, says domestic and Norwegian supplies will cover the low‑usage months, meaning liquefied natural gas (LNG) imports will be minimal this summer. The real challenge lies ahead. While renewable rollout is accelerating, gas will remain a core part of the UK’s energy mix for at least the next two decades. It accounts for about 37% of total gas consumption in 2024, with domestic heating being the largest single use. Replacing millions of boilers with heat pumps cannot happen quickly, especially given the current sluggish pace. Government plans for 2030 still require the full 35 GW of gas‑fired generation capacity to stay online as backup. Energy department data released in early 2025 showed gas demand “broadly stable” for the third consecutive year, representing roughly half of the nation’s 75.2% fossil‑fuel dependency. In the debate over new North Sea drilling licences, the key question is where future gas will come from. Oxford energy economist Sir Dieter Helm, speaking on a Chatham House podcast, warned that gas will dominate the energy supply for the next decade or two and that the cheapest, least polluting option is pipeline gas—not LNG. Analysis from Wood Mackenzie confirms this hierarchy. Pipeline gas from modern Norwegian platforms has the lowest carbon intensity, followed by UK North Sea pipelines. By contrast, LNG adds significant emissions during liquefaction and regasification, and US LNG is the most carbon‑intensive because much of it originates from shale gas with higher methane leakage. Wood Mackenzie’s import forecasts to 2045 paint a stark picture: if domestic production wanes, the UK could rely on US LNG for over 60% of its total gas supply by 2035. The firm notes that Middle‑East gas is geared toward Asian markets, while US cargoes are increasingly directed to Europe, raising concerns about over‑reliance on a single supplier. These projections underpin the argument for expanding UK North Sea extraction. More domestic drilling would reduce dependence on US LNG—a geopolitical risk given the United States’ tendency to use energy as a foreign‑policy lever—and would also lower the overall carbon footprint of the gas supply chain. Critics often claim that North Sea output is exported, so it does not improve national security. Two counter‑points are clear: first, gas delivered directly via pipeline to the UK network is inherently more secure than trans‑Atlantic cargoes; second, the UK could negotiate long‑term, fixed‑price contracts with producers, a model that worked well in the early days of North Sea development. None of this diminishes the importance of renewables and nuclear power. Electrification remains the long‑term goal, but gas will stay in the energy basket for years to come. Offshore Energies UK estimates that, with a pragmatic licensing approach, reliance on LNG could be limited to 6% of total gas supplies by 2035. Assuming political stalemate eases, the pending approval of the Jackdaw field—accounting for roughly 6% of current domestic production—could spark a more nuanced debate about the UK’s gas procurement strategy, moving beyond the simplistic “renewables vs. gas” narrative. Reflecting on the recent Iran‑UK conflict, Prime Minister Rishi Sunak highlighted the need for “secure, homegrown energy”. The logical follow‑up is twofold: accelerate electrification to cut gas demand, and while gas remains essential, avoid turning the UK into an “energy prisoner of the US”. Beyond the geopolitical and environmental benefits, expanding North Sea output would also support jobs, tax revenue, and the balance of payments.

Opening new oil and gas fields in the North Sea would send a shock wave around the world, senior climate diplomats warned, saying the move would imperil international climate targets, erode the United Kingdom’s reputation as a climate leader and embolden developing countries to exploit their own fossil‑fuel reserves.The UK government faces intense lobbying from the oil industry, Conservative MPs, Nigel Farage’s Reform UK party, certain trade unions and factions within the Treasury. Yet research shows that new drilling would do little to lower energy prices and would have almost no impact on gas imports.Two of the remaining large North Sea prospects – the Rosebank and Jackdaw fields – sit in a basin that is over 90% depleted and increasingly costly to develop. Even if fully exploited, they would displace only about 1% and 2% of the UK’s gas imports respectively, according to recent analysis.Senior figures in international climate diplomacy described the prospect of new drilling as dangerous for global emissions‑reduction efforts and a step back from the phase‑out of fossil fuels.Lord Nicolas Stern, professor at the London School of Economics, warned that “new drilling and a slowdown in climate action would be bad for growth and for energy security in the UK, and a damaging signal for the world.” He added that the UK’s pioneering climate legislation and its role as the first G7 nation to commit to net‑zero by 2050 give its actions “extra weight” on the global stage.An anonymous senior African negotiator reacted angrily to the proposal, stating that Africa would “reject any proposal for the UK to expand oil drilling” because it is “fundamentally inconsistent with both the letter and spirit of the Paris Agreement” and would “weaken trust with climate‑vulnerable nations”.Christiana Figueres, former UN climate chief and co‑founder of the Global Optimism think‑tank, argued that true energy independence lies in “scaling clean, domestic energy, not in extending the life of declining industries”. She cautioned that reverting to old‑fashioned oil expansion would lock in infrastructure at odds with the direction of the global energy system.The UK has been a vocal supporter of an upcoming conference in Colombia on the “transition away from fossil fuels”, a pledge made three years ago at COP28 that remains largely unfulfilled. However, the Guardian learned that Ed Miliband, the UK secretary of state for energy security and net‑zero, will not attend; the government’s climate envoy, Rachel Kyte, will travel in his place.Campaigners had urged Miliband’s presence, citing his pivotal role in securing a last‑minute deal at COP30 in Brazil last November.Experts caution that licensing new fields before the Colombian summit could undermine progress in persuading developing nations to forgo fossil‑fuel‑based economies and adopt cleaner energy pathways.Mohamed Adow, director of the Power Shift Africa think‑tank, warned that a UK approval would “send a shock wave around the world that short‑term interests are being prioritised over long‑term responsibility”. He stressed that many African countries are being asked to leapfrog to clean energy with limited financial support, and that wealthy nations continuing to invest in fossil fuels “undermine this message and diminish their credibility”.Several developing‑country officials echoed this concern, asking, “Why shouldn’t we tap into our own fossil‑fuel resources if the UK is doing so?” They argued that leadership on climate must be consistent with actions.An ally of Miliband praised the UK’s stance, calling “no new exploration licences” a “landmark global leadership position” that shows a major oil‑producing country can align policy with climate science to avoid a 3‑4°C warming scenario.A government spokesperson reaffirmed the administration’s commitment, stating that the UK has placed “clean energy and climate at the heart of its agenda”, and that it will continue to “stop issuing licences to explore new fields, in line with the science and in securing a just transition in the North Sea”.

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.
