The cost of buying wholesale gas & electricity will have increased from £359/yr last summer to current £1,069 & then to £2,245 in Oct This is a giant 6-fold rise – thanks to pricey gas – from Summer 2021 to Winter 2022 (Bloomberg: "Gas soars 700%") 2/…

Finally, big thanks to @Martin @Investec for sharing energy cap projections in recent months 7/ends

PS gas drives the price of electricity as well as gas, even though only ~40% of electricity is generated using gas That's how current electricity market works This is rapidly becoming a political talking point, but I suspect any changes will take years…

PPS even if a new PM wanted to "suspend" or "scrap" green levies, it's not actually that quick or straightforward to implement, unless you're happy to commit major energy market / policy vandalism…

@Chris Skidmore and @Paul Waugh wrote yesterday that a lot of candidates for PM are promising to ditch green levies, introduce a moratorium or move them to general taxation. Is it possible? Is it bad for climate? Could it even be good? The answers, as ever, lie in the detail...🧵
