"due to the high taxpayer subsidies"
I nearly stopped reading at that point (one supposes it was written by a Tory?). Subsidies for renewables are paid for out of energy bills. A person paying an energy bill may or may not be a tax payer. I am glad I have read this profile of the report - I was going to buy it - however with this type of expression one realises that that the report is politically biased with the aim of feeding propaganda to more extreme tendancy in the Tory party.
Quite what "carbon capture and storage" has to do with on-site renewables is anybodies guess (my company works with various players in the CCS space - nobody pretends that it is a cheap solution). One thing for sure, if we are de-carbonising the way we heat buildings then its either CHP or electric heating - and the latter in cities demands embedded generation of some sort. The "some sort" could be covered by RES.
