bobmeister: We humans will do what we have always done. Adapt.

If that means using less energy, that may well be the case, but in reality we will find new energy sources and even more news ways to use it.


The 19th Century doesn't look very appealing to me either.

This, increased energy use, will continue and expand because we like the way we live and we are in control.

Hands up anybody who wants a life expectancy of 40? Yeah, that's about what I expected. 

As to the climate. There is nothing on planet earth as complicated as the climate, it even beats the human brain. 

Anybody who tells you "I understand the climate" or says 'The climate will do this...' is lying or has a book to sell. Probably both.  

Didn't anybody tell you I was a hacker?

  ...There are actually increasingly scarce resources with regards to nuclear material required to run the world's nuclear power plants. It is assumed that there is some magically infinite resource of nuclear material that is available to run power plants. That is certainly not the case. It has to be extracted from the ground just like with oil, and there is an even more limited amount of raw material available compared to oil...

As another has pointed out with a link to an example there are such things as breeder reactors. You are also apparantly unaware of the difference between fission and fusion - with the likely, probably certain this century and absolutely certain in the human epoch, harnessing of fusion the supply of fusionable fuel on our planet alone essentially becomes infinite with negligible impact on the environment in mining it.

In the end the most abundant thing in the universe (as far as we know) is energy so I don't think we need have any concerns whatsoever about ever running out of it - there will always be plenty there no matter how long the human epoch.

The only trick is being able to harness it. But the current popularist focus on extremely low grade sources such as wind and solar, or using less, heads us to the disorder of a less well-being civilisation down the timeline because of rationing of energy (have a look at entropy and social entropy). It is also impeding us better applying ourselves to developing high grade sources such as nuclear (and those not yet discovered for the future) which would produce so much energy we will not know what to do with it all except to produce a better world.
