The trouble, as a new book by Cambridge physics professor David MacKay points out, is that much of what we are told amounts to little more than 'greenwash' - a series of pointless gestures and incantations designed to make us feel better about ourselves, to make companies more money and to justify hikes in taxation on 'non-green' activities.The problem, says Prof MacKay in his book Sustainable Energy - Without The Hot Air, is that the green lobby is being totally unrealistic about what is really needed to achieve the cutbacks in carbon dioxide emission it says is necessary.
No great surprises in the book, then!
