You have to be very careful here. Suppose someone installed a solar or wind energy system which actually worked well, and effectively "made them money" - but "broke environmental legislation", then they would be penalised for actually helping to slow global warming. Meanwhile, someone else can erect some mindless and useless thing such as a "modern windfarm" which is "within regulations" yet actually has a Positive carbon footprint, but since it doesn't help them either, they will be paid the money from the helpful people's thing as "subsidy" (for their insane heap of industrial scrap with a label under it - "Clean energy source" - as in The Tate Gallery.
No serious certification agency appears to exist at present, and so what is the legislation going to be based upon ? i.e. what will get it by as legal.
a) If it Actually does reduce CO2, nett, over one life-cycle
b) If it looks right (to the majority ?) and/or it's "the latest".
Rarely, and very happily, the two are synonymous !
