Thanks for a very well thought out reply.<p>&gt; By contrast, wind, solar, and hydroelectric power are rather simpler, and even geothermal is fairly straightforward.<p>My understanding is scaling these technologies is where the complexity may lie, and that it would so extremely difficult to support the growing energy needs of the world&#x27;s population using these technologies that they aren&#x27;t really even an option.  I&#x27;d like to be wrong.  Am I?
