The UK government is facing growing pressure to address the looming energy crisis sparked by the Iran war. Despite the £117-a-year cut to household utility bills announced in the autumn budget, energy costs are expected to rise again in the summer. The latest forecast from consultancy Cornwall Insight estimates the cost of a dual-fuel bill will rise by 17.6% from July.Labour ministers have been urging people to 'keep calm and carry on,' but critics argue that this message may be underplaying the scale of the challenges ahead. Andrew Sissons, director of the climate programme at Nesta, says the reality is that the global supply of oil and gas is going to be down by maybe 20%, and everybody needs to consume less.The government is trying to balance the need to address the cost of living crisis with the risk of sowing panic and denting consumer confidence. However, experts argue that a more nuanced message, such as 'keep calm but cut down,' could be more effective in encouraging people to reduce their energy consumption.Jill Rutter, of the Institute for Government thinktank, suggests that people can take steps to manage down their consumption, such as being more efficient and switching to clean electricity. The government is also facing pressure to reconsider its plans to reverse the Tories' 5p cut to fuel duty.As the conflict continues, the 'keep calm and carry on' message may sound increasingly adrift from reality. The government must navigate the challenges of addressing the energy crisis while avoiding panic and maintaining consumer confidence.

The Iran war has triggered a massive energy shortfall in Asia, forcing governments to ramp up their use of coal, the dirtiest fossil fuel. Countries across the region, including South Korea, Thailand, the Philippines, India, and Bangladesh, are trying to compensate for a drop-off in imported energy, much of which comes from the Middle East.Climate experts have warned that the increased use of coal will have a devastating environmental impact, and that the energy crisis should be a wake-up call for governments to invest in renewables. The crisis has highlighted the importance of renewable energy for energy security in Asia.The global market has flipped within four weeks from a healthy supply surplus to a severe deficit, leading to price spikes and fuel shortages. Almost 30bn cubic meters of LNG has been removed from global supply chains, with over 80% of this loss affecting the Indo-Pacific region.Experts warn that it will take years to recover LNG supplies and that the crisis will have a lasting impact on the energy landscape in Asia. Governments are racing to overcome shortfalls, with some countries introducing measures to reduce energy consumption, such as four-day workweeks and remote work arrangements.

The ongoing United States-Israeli conflict with Iran has triggered severe disruptions to global LNG supplies in the Gulf, creating the most significant energy market disruptions in recent years. The critical Strait of Hormuz, through which 27 percent of the world's maritime oil trade and 20 percent of LNG shipments pass, has been brought to a near standstill.In response to the conflict, oil-producing nations such as Saudi Arabia have rerouted oil through alternative pipelines, while Qatar has completely halted LNG production at its Ras Laffan and Mesaieed facilities following attacks on its energy infrastructure. This disruption comes as natural gas makes up about a quarter of global energy consumption, raising widespread concerns about the impact on nations heavily reliant on gas imports.Natural gas is formed over millions of years from decomposed organic matter subjected to intense heat and pressure beneath the Earth's surface. LNG represents natural gas that has been cooled to -162 degrees Celsius through cryogenic processing, shrinking it to a 600th of its gaseous volume. In its liquid state, LNG is colorless, odorless, and non-flammable, making it safe and efficient to transport across vast distances.Before liquefaction, the gas undergoes purification through water-based solvents and molecular sieve beds to remove impurities including carbon dioxide, hydrogen sulfide, water, and mercury. Heavier hydrocarbons are then separated from methane and ethane through fractionation. The resulting fuel is typically composed of 85 to 95 percent methane, with small amounts of ethane, propane, butane, and nitrogen.LNG is stored in large insulated tanks without requiring high-pressure infrastructure, then pumped onto double-hulled carriers for shipment to terminals worldwide. At destination facilities, LNG is heated using seawater or warm water baths until it vaporizes—a process known as regasification—before being distributed through pipelines for consumption.Once returned to a gaseous state, LNG serves multiple purposes globally. Residential applications include cooking, heating, and electricity generation, while supporting hot water systems in homes and heating for commercial buildings. In power generation, LNG offers a comparatively low-carbon alternative to coal and oil. Industrial applications span fertilizers, plastics, paints, and medicines, with LNG also used to fuel heavy-duty vehicles and ships.The disruption has particularly affected agricultural production, as Gulf nations export close to half the world's traded urea—a key fertilizer component. Natural gas serves as both the primary feedstock and fuel for fertilizer manufacturing, with the halt in production forcing producers across the region to suspend or reduce operations.While primarily valued as an energy source, LNG processing yields significant by-products with industrial and medical applications. The most notable is helium, extracted during cryogenic processing. With global helium production estimated at 180 million cubic meters annually, the disruption to Qatar's LNG facilities has removed approximately 5.2 million cubic meters from the market each month—accounting for about a third of global monthly production.Helium is critical for cooling superconducting magnets in MRI and CT scanners, with the average MRI machine requiring about 1,700 liters of liquid helium. The element is also vital to the data center industry, where it conducts heat away from silicon components, preventing damage to semiconductors. Additionally, the natural gas value chain generates petrochemical derivatives that serve as feedstock for manufactured goods, including medical-grade plastics.According to the International Gas Union's 2025 World LNG Report, 411.24 million tonnes of LNG were traded in 2024. The United States emerged as the largest exporter with 88.4 million tonnes, followed by Australia (81 million tonnes), Qatar (77.2 million tonnes), Russia (33.5 million tonnes), and Malaysia (27.7 million tonnes). Together, these top five suppliers account for more than three-quarters of global LNG supply.China was the largest importer with 78.6 million tonnes in 2024, followed by Japan (67.7 million tonnes), South Korea (47.1 million tonnes), India (26.1 million tonnes), and Taiwan (21.8 million tonnes). These top five importers constituted nearly 59 percent of all global LNG imports that year.South Asian nations face particularly severe risks from the current conflict. Pakistan, where natural gas accounts for 28 percent of electricity generation for its 250 million people, and Bangladesh, where gas supplies half of all electricity for its 176 million population, are heavily dependent on Gulf imports. Qatar and the United Arab Emirates supply approximately 99 percent of Pakistan's LNG imports and 72 percent of Bangladesh's.In response to the energy crisis, Pakistan has implemented emergency measures including a four-day workweek for government employees and extended school holidays. Bangladesh has reduced gas supplies and is seeking nearly $2 billion in international loans to fund energy inputs and maintain price stability. India, which relies on Gulf nations for about half of its LNG and generates 5 percent of its electricity from gas, has shifted toward coal usage as LNG disruptions continue.

Progressive lawmakers Bernie Sanders and Alexandria Ocasio-Cortez have unveiled a bill to place a moratorium on the construction of AI datacenters in the US. The proposed pause aims to ensure the AI boom benefits workers, protects the environment, and does not harm communities.The bill's introduction comes amid growing concerns about the rapid buildout of AI infrastructure and its impact on energy consumption, electricity bills, and the climate crisis. Sanders and Ocasio-Cortez argue that a temporary ban would give the US government time to create strong federal safeguards for AI.“AI and robotics are creating the most sweeping technological revolution in the history of humanity,” Sanders said. “The scale, scope, and speed of that change is unprecedented. Congress is way behind where it should be in understanding the nature of this revolution and its impacts.”The proposal has gained traction, with at least 11 states considering similar policies. Advocacy groups, including Food and Water Watch, have also called for a federal datacenter moratorium, citing concerns about the sector's impacts on electricity bills and the climate crisis.The bill's supporters argue that datacenters' massive energy consumption and water usage have sparked controversy, especially in drought-ridden areas. If current trends continue, datacenters may account for nearly half of all US emissions from the power sector.“We cannot sit back and allow a handful of billionaire Big Tech oligarchs to make decisions that will reshape our economy, our democracy and the future of humanity,” Sanders said. “We need serious public debate and democratic oversight over this enormously consequential issue. The time for action is now.”

The concept of joules, named after Victorian-era physicist James Prescott Joule, has evolved significantly over time. From a simple unit to describe the effort required to pick an apple off the floor, it has grown to encompass larger units such as kilojoules, megajoules, gigajoules, terajoules, petajoules, exajoules, and now zettajoules. However, humanity's increasing energy consumption and its impact on the planet's energy balance have far outpaced our understanding and management of these growing energy levels.

The world is currently experiencing a severe energy crisis, surpassing the combined impact of the 1970s oil shocks and the Ukraine war, according to Fatih Birol, Executive Director of the International Energy Agency (IEA). Speaking at a media event in Australia, Birol warned that the energy crunch prompted by the US-Israel war on Iran has exceeded the 1973 and 1979 oil shocks and gas shortages stemming from Russia's 2022 invasion of Ukraine.Birol stated that the crisis is equivalent to two oil crises and one gas crash combined. He noted that the effective closure of the Strait of Hormuz and attacks on energy facilities have reduced global oil supplies by about 11 million barrels per day (bpd), more than double the combined shortfalls of the 1970s crises. Additionally, liquefied natural gas (LNG) supplies have been reduced by about 140 billion cubic meters, compared to a shortfall of 75bcm in the aftermath of Ukraine's invasion by Russia.At least 40 energy facilities across nine countries have been severely damaged in the conflict, according to the IEA chief. Birol emphasized that the global economy is facing a major threat and expressed hope that the issue will be resolved soon.Birol also expressed concern that the scale of the crisis had not been fully understood, which prompted him to speak publicly about the situation. The IEA has proposed measures to reduce energy consumption, including facilitating remote working and carpooling, and lowering speed limits on motorways.The IEA chief is in consultation with different countries about releasing more strategic oil reserves if needed. However, he emphasized that the single most important solution to the crisis is to unblock the Strait of Hormuz, which usually carries about one-fifth of global oil and LNG supplies.

UK Prime Minister Keir Starmer has indicated that the government is considering providing support for household bills next winter, as the energy price shock triggered by the Iran conflict shows no signs of abating. Speaking to the Commons liaison committee, Starmer emphasized the need to examine 'every lever that's available' to help households cope with the cost of living impact. The government is reportedly discussing contingency plans at an emergency Cobra meeting, which will be attended by the governor of the Bank of England. Starmer suggested that any support would likely be targeted at the poorest households, rather than a universal bailout, which he acknowledged would be expensive. Ministers are also exploring means-testing support when the next energy price cap comes to an end in June, as well as in the autumn when energy consumption and bills are higher. 'We're looking at in the first instance what happens when the current price cap ends, which is the end of June,' Starmer said. The prime minister warned that despite US President Donald Trump's decision to postpone airstrikes on Iran's power plants, the energy crisis could continue for months to come. 'All of our focus and energy has to be in the swift de-escalation, but we've got to plan on the basis that it could go on for some time,' he said. In addition to support for household bills, the government is considering giving the Competition and Markets Authority (CMA) 'further teeth' to prevent companies from exploiting the crisis through price gouging or profiteering.
