yep, when I drove through southern Germany it seemed every third house had PV, and houses with a hundred panels were not unusual. Many flats also actually had PV and thermal systems on their roofs. I am amazed more freeholders haven't utilised their roofs to increase their returns on ground rent.
There's no doubt PV works, Germany have proved it, but you have to be prepared, as a nation, to invest in the new technologies. I think binning Nuclear is a mistake though, and I still think it's window dressing. They don't have a viable alternative at the moment and it's just a sop to the greens.
