The likes of BP won't make some massive profit by the end of the year due to writing off their Russian assets.
To cover the increase in energy bills for the next two years would be on the order of £100bn+ depending on where you draw the price cap line (April's or August's) and if every household gets it out of the 28 million or so.
If you seriously think oil and gas executives are making off to a tenth of a trillion pounds, I've got a bridge to sell you.
Incidentally, that money they do rake in is likely a one off event if the global economy collapses, and with it, the CAPEX for getting us out of this situation. Because without investment in the mid- to long term, we'll be paying FAR more in the near future than what we'll pay next year.
Additionally, subsidising consumption is the dumbest thing people in power could do now. Do they think they can buy more gas than exists if we give everyone a tax break?
People need to wake up and actually read a physics and economics book sometime instead of assuming this is profiteering. Like suddenly shutting down 40% of Europe's energy means prices won't be affected? What the fuck?
