How will we power the future? Will we harness the wind that blows across the plains? Will we build a collective of small, modular nuclear fission reactors, safer and more efficient than today's ungainly nuclear power plants? Or maybe the success of giant solar plants like California's Ivanpah Solar Power Tower will inspire more solar projects?
There are a variety of renewable power options that could prove successful in the future. All of them carry advantages and disadvantages, of course. You'll find unbiased information on both sides at procon.org, including neatly laid out arguments for and against lots of different energy sources. There is also a detailed historical timeline of energy source development that will answer any question you could pose on the subject.
So where will the future of energy take us? Wind energy is the fastest growing energy source in the world now, with lots of potential benefits. Hydropower is the renewable energy source that produces the most electricity in the U.S., though tidal energy (one component of hydropower) has yet to be developed in this country.
