I'm all for nuclear power. No matter how much the green folk claim, the world cannot be run off of windmills.
Biofuels have led to huge rises in food prices which are hitting the poorest hard.
Fossil fuels are only going to go up in price, they're simply not cheap enough in the long term.
Tidal is possible, but limited. Same for schemes like geothermal.
Solar has potential, but is costly, and only works for half the day at best.
The vast majority of nuclear waste can be dealt with by reprocessing, which simultaneously removes the need to bury highly radioactive material in a ditch, and also hugely increases the amount of energy extractable per unit mass of fuel.
Countries like the US which do not reprocess fuel are being downright wasteful and making things difficult for themselves. (Though I suppose they can just dig it up later if needed.)
That said, I would be all for covering the a good chunk of the Sahara in solar collectors too and running HVDC lines to Europe. I dread to think how much that would cost though.
