You could have just as easily mentioned that the sun is eventually going to kill off all life on the planet. Neither fact is relevant.
The timescales most certainly are relevant. We're currently in a pretty serious situation with respect to global carbon emissions. Given that we selfish humans won't sacrifice our power requirements, fission almost certainly needs to provide some of our power in the short to medium term future. I don't know of any "renewable" resource that fits with your "inexhaustible over a timescale of centuries" requirement -- land is required to capture wind, coast to capture tide, etc. and the numbers don't add up (see e.g. http://www.withouthotair.com/).
