I'm not at all sure why using ROCs to guarantee that a source of electricity is renewable is any less "green" than having a direct relationship. OfGen would be all over them if they made a false claim.

It was a rhetorical question - I too can use Google - the point is clearly made in the second quote I posted from Bulb's site:

Every unit of electricity we supply can be traced back to a renewable source.
