The question put to Guardian environment editor Damian Carrington was deceptively simple: how hard are politicians actually working to decouple gas and electricity prices? Behind it lay something more urgent — the recognition that for most households in Britain, Germany, Japan, and beyond, the switch from a gas boiler to a heat pump is not a values decision but an arithmetic one. Until electricity becomes cheap enough, green technology remains a choice only the comfortable can afford. Carrington and energy journalist Jillian Ambrose fielded questions for several hours in a live exchange that ranged from North Sea oil field development — specifically the contested Rosebank and Jackdaw projects — to the size of fossil fuel subsidies relative to industry profits.

One theme surfaced repeatedly: the fossil fuel industry's political spending continues to distort the speed of transition. Asked directly whether anyone inside that industry accepts responsibility for climate change, both journalists struggled to point to meaningful, structural acknowledgement. Lobbying expenditure, by contrast, runs into hundreds of millions of dollars annually across Washington, Brussels, and Riyadh. Yet the session ended on a note that was neither triumphant nor despairing.

Carrington's closing argument was essentially an economic one: green technology and lower-carbon ways of living are already cheaper, cleaner, and in many cases more convenient than their fossil alternatives. The trajectory, he suggested, is not seriously in doubt. What remains genuinely open is the human cost accumulated during the years it takes to arrive. Droughts, displacement, and energy poverty are not abstract futures — they are already being measured in lives, in harvests lost across sub-Saharan Africa and South Asia, in reservoirs that no longer fill.
