It is interesting that from a simple question can come many points of views and sometimes the answers don't really even answer the question. Of course this is common sense, especially from the perspective that the question is rather broad and it is being posed to scientists who tend to think more abstractly. I just find it interesting to read various perspectives that come from a broad question and we get a sense of how many different angles there are to a problem. It is especially helpful to read responses that are within a context of how the question is being addressed by the person responding (e.g., "From a purely pro-environmental standpoint...").
I'm curious as to how well the answers posted are matching what Leslie is hoping to get as an answer... Perhaps she left it broad to see the wide variety of responses she may get, or perhaps she'll need to refine her question more... As for my own thoughts on the question - the phrase "power the world" gives me difficulty in answering the question without launching into a long essay. Considering this question from a "manmade" standpoint, we have to consider all of the abililties (e.g., economic, political) of various countries to power themselves so that the whole world may be powered. So, are we talking about what is most feasible in terms of each country being able to optimize its power and yet remain environmentally conscious? If so, that means many different powering systems that is achievable (feasible) for each country. Or are we leaping years into the future to what may be a single, most feasible and environmentally-friendly power system for the entire world? If so, then I like the answer of Steve Kunz in that the solar power from the sun could eventually become technologically feasible in a broad sense.
