The one FACT that wasnt there is that the Denmark electricity grid is linked to neighbouring countries.
I think it was less than a year ago Holland was becalmed and had to import big heaps from Germany.
I prefer to judge renewables, not so much on return of capital costs but on the return of the energy costs and I suspect that a wind turbine would take a long time to pay a dividend on it's energy input.
There was, I'll admit, a very encouraging article on Jim Puplava's FSN (not known as "green") which I'll do a search on and post what I find.
