Another big energy company revealed its price rise today, with a fair bit of blustering about so called "green taxes".
For many years now the big energy companies have had an "obligation" to spend money on helping people who live in energy inefficient houses to save energy. Of course they hate this - they would, wouldn't they because it means the people who get the grants, subsidised boilers etc will be paying lower bills won't they. About half of "green levy" goes on just this - grants to people who need them. (Currently available from energy companies under the ECO scheme)
And the other half goes on supporting renewables - e.g. a secondary school I was involved in was helped to get a wood-chip fuelled heating boiler by EON. Also reducing their energy bills.
This is one of the few ways that the government are trying to reduce CO2 emissions and fossil fuel consumption by the UK - putting this obligation on energy companies.
The energy companies would like to wriggle out of their "obligation" - but we should not be tricked into thinking this is a good thing, by talk of "green taxes" - including by the PM.
