Britain’s energy industry faces collapse thanks to Labour’s “chaotic and needless” rundown of the oil and gas sector, one of its biggest union backers has warned. [some emphasis, links added]Louise Gilmour, Scotland secretary of the GMB union, says “delusional” net-zero policies championed by Ed Miliband are causing “arguably the most destructive industrial calamity in our nation’s history”. It puts Labour on a collision course with its third-biggest union backer, which donates £1M (US$1.4M) a year to the party. In some cases, oil and gas firms are paying 120 percent tax on their profits because of the Government’s energy profits levy (EPL). But instead of drilling for new sources of North Sea oil and gas, Britain is relying on imports from Norway, which found a huge new oil field last year because it has not banned exploration.
