Individ has pasted a comment, and this is such a rare and exciting event that I put my reply here as well as back in the original posting, because that is 80 days ago and well buried here: Mabinogogiblog: "Nuclear Power is the answer to global warming" - NOT
Your concept of mineral resources is quite limited. The amount of reserves available at any time is not a predictor of how much of that commodity can be consumed into the future.
Here, let me give you an illustration the sinks your argument completely. Proven oil reserves at the end of 1993 equaled 1023.6 billion barrels. During the following ten years, 264 billion barrels were produced and consumed, yet proven reserves at the end of 2003 equaled 1147.7 billion barrels. See? The economy is dynamic. There is entrepreneurship, venture capital, human ingenuity, and "supply and demand".
Individ confuses resources, which are the absolute amounts within the Earth, and reserves, which are the amounts of thos resources identified by mining companies as next on the list for exploitation.
It is incontrovertible that reources are finite and will therefore run out. As they run douwn they will be more difficult to extract, and more expensive. Supply will also outstrip demand.

Uranium, oil, coal and gas are capital, finite goods. Solar energy is the income of the planet, and is the real fuel of the future.
