WE HAVE all come to rely on the co-leader of the Scottish Greens, Patrick Harvie, to come up with expensive ideas for the unworkable. His latest foray into this world is to stop Scots getting grants for solar panels unless they are putting in very expensive and quite possibly ineffi-cient new heating systems. The grant will be pathetically low but the heating system costs will probably be astronomically high. Mr Harvie seems to spend a lot of time planning how he can save the world by making the lives of Scots very miserable indeed. Is there a Nobel Prize or a job at the United Nations for this?
