Large areas of the world cannot be powered with wind or solar. To use a Canadian example, the west coast of British Columbia is not a sunny place, to put it mildly, and not particularly windy. In other places, the solar energy is simply too weak, which is why Edmonton is often sunny and -30 degrees C. I find the whole "just use solar and wind!" argument is often made by people who live in warm, flat places.
