The escalating conflict between the US and Iran has sent global energy markets into turmoil, with far-reaching consequences for the UK. As an expert commentator, I find it intriguing to explore why the UK, despite its growing reliance on renewables, remains so vulnerable to these energy price shocks.
The Impact of the Iran-US Conflict
The war has disrupted oil and gas supplies, pushing prices to unprecedented levels. Oil prices have soared past $100 per barrel, with analysts predicting a potential jump to $150 by March. This has immediate and severe implications for the UK, where energy bills and fuel costs are set to skyrocket.
Vulnerability to Fossil Fuels
Despite the UK's impressive progress in renewable energy, with renewables leading electricity generation in 2025, the nation remains heavily dependent on fossil fuels, particularly gas. Around 30% of the UK's electricity comes from gas-fired power stations, and over 70% of homes rely on gas for heating and cooking. This dependence leaves households exposed to volatile international markets.
The Marginal Pricing Model
A key factor in the UK's vulnerability is its marginal pricing model for electricity. This system sets electricity prices based on the costliest power source needed at any given moment, which is almost always gas. As a result, even when renewables supply the majority of power, the price is dictated by gas, exposing households to swings in global gas markets. This system has come under increasing scrutiny, with critics arguing for a more balanced approach.
Political Pressure and Long-Term Solutions
The impact of these price shocks has sparked calls for political action. Many see this as an opportunity to make decisive long-term decisions to reduce uncertainty and tackle the climate emergency. The UN, led by Secretary-General António Guterres, advocates for decarbonisation as a means to reduce the burden of international conflict. Guterres highlights the benefits of homegrown renewable energy, which cannot be blockaded or weaponised.
Broader Implications
The conflict's impact extends beyond energy prices. Britons face increased mortgage rates as interest rates rise, and drivers are set to experience major fuel cost increases. This economic strain underscores the need for a long-term plan to protect consumers and reduce reliance on volatile fossil fuel markets.
In conclusion, while the UK has made significant strides in renewable energy, its continued dependence on fossil fuels and the marginal pricing model leave it vulnerable to global energy shocks. The current crisis highlights the urgent need for political action and a transition to a more sustainable and resilient energy system. Personally, I believe this moment presents a unique opportunity for the UK to lead the way in tackling the climate crisis and building a more secure energy future.
