WINDPOWER - 29% BY 2030?

This article on world energy gives some very interesting predictions of how the world's electrical energy is to be produced in the future. The estimates must be looked at with a great deal of scepticism; for example one body predicts windpower will make up 29%, whereas another suggests 3.5%. Such a wide variation suggests that we simply cannot predict what is going to happen. Technology is changing so rapidly that by 2030 the whole picture could easily change completely.
