(the watered down green energy policy is a hugely regrettable example of how Labour are failing to be anything other than 'not Boris' and a greater push to make Starmer actually stand for something would be to the benefit of everyone)
I suspect and hope (and I'm perfectly willing to accept I could be giving them credit they don't deserve) that the apparent watering down of their green policy is a pre-emptive move to prepare the party for the coming economic crash that will hit when Brexit lands on top of Covid. It's likely to be a wildly unstable time, and the only potential narrative the Tories have is to paint Labour as even more economically irresponsible by saying 'we're in a crisis and Labour have these vast spending promises!'. Given how far away the election is, at this stage I'm ok with Labour playing clever and dodging Tory traps. If they still hold a watered down green policy in 2-3 years then I'll know it's ideological not just a temporary tactic for political expediency.
