Hi Rob
mmmmm green energy supply eh
In a lovely shiney green world I'm sure its all true, in reality I think you'll find its a lot of clever marketing, yes some of the energy is and will be greenly produced.
However dont forget the electrical industry like all industries are in it to..........make profit and keep the shareholders happy

so unless green energy is profitable then there not too interested in my opinion, yes they pay lip service to it all but if you actually look at it they could have been producing green power years and years ago but they havent, exactly the same can be said for EV's etc again the car industry could have been producing EV's that peeps could buy years ago but again they havent........why not..........cos its not profitable
Interesting bit of info : Did you know we import about 1000MW of Electricity or there abouts ALL the time ( day in day out, 365 days a year) from France, which from memory is about the most the cables can cope with (data from about 5+years ago)
Why do we do this.......cos its cheap nuke generated power from the 4 nuke stations dotted along the northen edge of France and hence once re-sold back out can make them a lot of profit.
So as for these so called green electrical sellers selling proper green electric I am very sceptical. The only real way of knowing your getting true green energy is make it yourself
I certainly wont be swapping my supplier for a more expensive so called "green" energy unless they can PROVE and show REAL evidence that they are doing what they say they are doing.
Just my take on the subject
