Well it's more than just whether we "have enough time," what I wonder about is whether it's even possible to do the square miles of solar panels and wind farms *without* cheap oil. The green tech stuff is all value-added, it's at the top of a big pyramid that's supported by cheap oil. Food is going to be a problem. Since you're interested in the farm angle, have a look at this doc Ludi posted if you have time:
http://cdn.static.viddler.com/flash/pub%20...%20y=ce56603dThe documentary focuses on the UK, but it's food for thought. They're a food importer. They have some farms, but nobody wants to farm anymore -- average farmer age is like 60 years old. When the peak oil decline gets in gear, and if global shipping sputters, people on that island are going to go hungry no way around that.
And when there's not enough food, everything else comes to a screeching halt. Starving people don't build solar panels and nuclear plants -- that's high tech stuff that requires a global supply chain running smoothly to support it. For example.. can we even build green tech in the US if globalism breaks down? We depend on China now, and many other countries. Globalism requires container ships and you can't run those on sunshine.
Someone would have to do the numbers to get to the bottom of this debate.. the essential question is whether or not we *can* transition from cheap oil to very intensive and supply chain dependent sources of energy like tar sands, massive solar panel farms, wind farms, and as yet to be perfected far out tech like tidal power. The feeling I keep getting with the green tech is that it's like using even more energy to make energy so there's some diminishing returns there. Or at the least life would be very different -- not even enough electricity to have the lights on more than a few hours in the evening much less a nation of 340 million buzzing around in EV's.
But I could be wrong. On the hopeful side, it's high prices that drive alternatives -- necessity being the mother of invention and all that. But still the oil *is* running out. Mos posted an article about Saudi Arabia planning to transition to solar panel farms so that after peak oil they can export electricity. But as oil gets more scarce, is all that Jetsons stuff even possible?
$this->bbcode_second_pass_quote('', 'C')an someone point me to a thread on the forum that gives projections for oil production in million bbl per day for the oil producing countries (for 2015, 2020, etc)? Plus, I would be willing to share my spreadsheet with others who want toy with it to create their own projections. Are there peak oil spreadsheets available for download somewhere?
I've seen those charts posted around here, gosh can't think of where to find one. You could have a look at the peak oil subforums, it's in there somewhere. If you don't get an answer in this thread try posting your question with a new thread in the peak oil discussion subforum.
