at work right now, but the newest version plants (nuclear) are less harmful to the environment (provided they don't blow up) than solar (making the panels is pretty toxic). Just for the rate at which energy consumption is expected to grow and how much nuclear can provide it seems the most logical way to go... plus you can recycle nuclear waste and reuse some of it (lot to read but http://www.world-nuclear.org/info/Nuclear-Fuel-Cycle/Fuel-Recycling/Processing-of-Used-Nuclear-Fuel/). Honestly I'm happy with solar or wind too, don't get me wrong. Once that gets to a point where its able to harness enough energy to light up the entire world like New York or Tokyo that'd be amazing.
