wind turbines are only part of renewables solution, but advantageously placed they can be highly efficiency, unlike solar which can only ever be 50% efficient at best, but in order to solve the northern hemisphere problem of "AGW" they have been used to good effect in places with abundant wind and sunshine. There is an electricity grid for a reason. The big problem for both is they give twenty years at best unlike hydro which is a century long project. The Keystone project transports the most polluting carbon based energy on the planet so not really a good idea and anyway its Canadian oil, let them build their own refineries, they might be ultra competitive
Sorry, but that's a really poor post. We all know electrical grids are there for a reason. Solar is not even under discussion. Coal is the most polluting carbon based energy and Keystone did not move coal. Wind only makes sense because our out of money government subsidizes it. As to letting Canada refine it's own oil, that's completely ridiculous. Why would we want to give business away in that manner? That's the Australian model as the graph below shows.
