No, I don't think so. Windmills and Geothermal heat have vast unmeasured potentionl. It may be they will each provide about a third of all the world energy needs. Barge mounted Windmills are already being tested, the ocean anchor details are being developed, most nations have access to the oceans. This source will become very big, very soon. Use of the electricity to produce Hydrogen, by electrolysis, will greatly increase its use. All nations will want to participate. Geothermal has one danger, in Colorado and Russia they found that extracting steam, in a few sites, led to earthquakes. In time, they will learn to identify the danger and drill holes in stable plates. Solar is growing rapidly with the use of thousands of mirrors to focus on an elevated boiler. They are now very big and rapidly growing in the Mojave Desert. Like weeds? Bad pun!. A desalination plant driven by solar thermal units is a natural. It will solve California water problems.
