It's hard to find someplace on earth where the sun is not shining and/or the wind is not blowing. The idea is a power grid. Besides, when the sun is shining and the wind is blowing, some of that power can be used to charge batteries for use when it's dark and still. No brainer.

Unless the moon decides to go off on its own, which astromomers tell us is not due for a few years yet, tides and ocean currents should be around for awhile. There are all kinds of ingenious ways of deriving electrical power there. And, no, the power derived would not be limited to coastal areas. Remember wires?   That's how electricity gets from Ross Dam, out in the tall and uncut, all the way to Seattle.

One can find all sorts of reasons to give up, especially if there is something that's been done before and some folks think is more convenient. But when everyting is toted up, nuclear power doesn't look that good. We're already finding nuclear waste to very inconvenient.
