Paul Homewood's analysis of expected future increases in household electricity bills is sobering stuff. Buried in the back of a House of Commons report on electricity prices we find that the cost of greenery is currently 10% of the average household bill (say £1200). This is expected to rise to 33% by 2020, which would make the bill £1450 or thereabouts, and to 41% (£1540) by 2030.
However, the costs of all this greenery fall, in the first place, mainly on non-domestic users - two thirds in fact. But the charges to industrial users simply gets passed onto consumers anyway (some of them being overseas consumers, but the majority are in the UK). So while domestic users are picking up an extra £450 in green costs (1540 - (1200/1.1)), in fact they are also eventually going to have to pick up most of the tab for the £900 charged to industrial users as well. That means by 2030, costs to consumers will have doubled.
