This is just ridiculous - the projected population of 9 odd billion people in 2050 will be perfectly capable of living prosperously once our energy and industrial production systems have been reconfigured.

Solar and wind aren't the only large scale clean energy options - there is a lot of power to be captured from ocean (tidal and wave) and geothermal sources as well.

Big Gav,
Didn't know you were back from hibernation.
Some solidly good new posts on your web site:
http://peakenergy.blogspot.com/

p.s. IMHO, the movie, Children of Men is a religious piece, it was initially released last Christmas

p.p.s. How do you have time for doing all that research and posting?

Big Gav was very kind in the early days of The Oil Drum...hell of a thinker and aggregator that guy.

Thanks guys - glad you still find time to keep track of what I'm up to.

I'm slowly re-emerging from hibernation, though I may take a week or two off this month to write a long post I promised the Alpha Male Chimp Who Can't Drive a long time ago...

As far as time taken to write my stuff goes, I usually find 2 hours a day is sufficient. Basically I don't watch much TV, so that is usually possible most evenings.

To do all that in 2 hours is remarkable.

I find it takes 2 hours for me just to read through the flame wars in a single TOD post, and then I find myself to be just like other humans and reptiles, merely having wasted another day without preparing for the coming apocalypse. :-)

Well - when I'm posting regularly I rarely have time to read through comments (at TOD or elsewhere) which is why I rarely comment here myself.

I certainly waste more time on the blog than I should - I've got lots of real world things to do as well, although I've decided its best to work towards avoiding the coming collapse of civilisation :-)

I should note some of my larger or more complex posts take a lot longer than 2 hours - something like "The Shockwave Rider" or "Bright Green Buildings and Dark Green Buildings" can take months to slowly assemble. Then some minion of big brother goes and bans it (The Shockwave Rider) anyway without even telling me which bit is annoying...

The idea that Children Of Men is a religious movie is an interesting one - I hadn't noticed it was a Christmas release, but given the prime spot occupied by the baby in the movie that makes a lot of sense...

Well, probably not. I've been putting together the numbers on all the options, and tidal, wave, and geothermal are pretty limited -- see this on tides and geothermal, and the links there to previous summaries of hydro, solar, fission, etc. options.

Basically the only large scale options (more than 10 times present world energy use in total renewable resource - of which we could only ever harness a few percent globally, or hundreds of millions of years worth of non-renewables) are:

* "water" - hydro + if we could somehow capture the latent heat energy associated with water vapor in the atmosphere, total about 3000 times present use

* solar - total about 13,000 times world use, or more if we go off-planet

* fusion - about 150 billion years of present world energy use from D+D fusion

* fission - about 600 million years of present world energy use from U-235.
