I really believe that Nuclear Fusion will be the power source of the future. Maybe within the next 10 years we will have achieved a sustained reaction, and within 20 years we will be using it to power countries. Anti-matter really does just seem like sci-fi (not the good, comes true after a while a la 'mobile communications device' we have seen). Anti-matter is exactly what it says on the tin, the opposite of matter. Considering that it takes immense amounts of energy to create AND store it, there is then the issue of controlling it, as it also destroys the matter it comes into contact with, hence being a very unreliable power source. of course, these other sources like solar, tidal and wind WOULD be great if they were strong enough and reliable enough. The only use of the sun I can see is for solar-sails.
