A battle between the world's two energy superpowers, the US and China, is unfolding on a global scale, with significant implications for household energy bills and climate change. The soaring oil and gas prices following the US and Israeli strikes on Iran in February have pushed up energy costs, potentially causing an increase of over £460 per year for a typical UK household. This escalation comes as Europe's winter gas stores are at their lowest since 2011, with demand for gas increasing during the colder months. The stakes are high, as the outcome of this contest will determine not only what the world pays for energy but also how quickly carbon emissions can be reduced to mitigate climate change. As world leaders convene in Antalya, Turkey for COP31, the same tension is being felt around the globe, with energy and climate policy becoming a front line in this international struggle. The UK finds itself caught in the crossfire, as it imports nearly a quarter of its gas from America and much of its clean energy technology from China. As the UK government contemplates approving new North Sea gas fields and potentially larger oil fields like Rosebank, the question remains: which path will the UK take, and what will this mean for household energy bills?
