$this->bbcode_second_pass_quote('Sixstrings', '')$this->bbcode_second_pass_quote('hardtootell-2', 'i')f this article along with its excellent graphics and well respected source do not convince you, I think there may not be much else I could offer. It shows how much oil we burn/yr and what the alternatives would be if it needed to be replaced.
http://www.spectrum.ieee.org/jan07/4820Thanks for linking the graphic, but I'm not swayed. To clarify by the way, I'm not trying to be difficult here, and I don't plan on becoming a perennial doubter on the forum. I really don't have a dog in this fight, other than curiosity about the truth. So this should be my one and only Doubting Thomas thread, after a long time on this forum I just got in the mood for some objectivity.
Now back to that graphic.. first of all, a CUBIC MILE of oil is of a lot oil. Secondly, what the heck are these generic "WIND TURBINES" and "SOLAR PANELS." There is a multitude of different systems, with the latest being the most efficient. So which systems is the author using to represent all "solar panels" and "wind turbines"?
And then the coal part of the graphic, 104 plants. Ok, so? We have 600 coal fired plants in the US right now. I don't see what would stop us from building more. And before anyone mentions greenhouse gasses, I'll say it again -- when the peak comes, nobody will sacrifice their lifestyle for the planet's sake. The engines of industry will continue, whatever the costs.
Lastly, the graphic seems to imply that these alternatives would need to be a TOTAL REPLACEMENT for that cubic mile of oil. Well as we all know, peak oil isn't about running out, it's about dealing with a SHORTFALL -- not a sudden and total disappearance.
And so, all the other forms of energy just need to make up the shortage as we head down the peak oil curve. It could take another hundred years to get close to hitting the other side of the bell curve, so it could be argued this is gradual enough for these alternative energy sources to take up oil's slack.
Also, everyone here is assuming current usage will just continue as it is on into the future. When a peak on light sweet becomes obvious, there will likely be much more conservation to preserve the remaining oil. For an honest prediction here, you'd have to start factoring in the effects of an all-electric vehicle fleet. Petrol would naturally become reserved for what cannot be replaced with electric power -- things like air and sea travel, plastics, chemicals, etc.
1cubic mile of oil = rougly 26.363.984.360 barrels of oil (which seems a lot, but I don't know that much about oil production -> how many years of curent consumption is that worth?)
After reading the article, that would be one year worth of oil consumption. (is that is what currently being used, or is that the energy being used that is extracted from it, I'm still confused).
Like burning 1 liter of oil (petrol) in an ICE gives you a ..?% efficiency? but the 1kwh from a solar panel/windfarm/nuke can be used with a very high efficiency in any electric tool (appliance or electric car)
Does anyone have an idea how many windgenerators/solarpanels/nukes are installed every year globablly?
For example, due to tax reductions and susidies the amount of solar panels that are going to be installed in Belgium will triple this year as opposed to last year. (not sure how many MW that will be in total)
I don't want to dispute peak oil. But even if it's "late" now, if we drastically switch from oil to renewables (together with conservation (which doesn't always mean loss of comfort or loss of job -> for example replace a regular 100watt led bulb with a CFL light bulb) and invest locally (instead of oil rich middle-east countries) a considerable difference and softening of the crash can be done.
Actually investing locally also means more local jobs (maintenance, production,.. of windfarms, solar, ..) instead of prepping up some distant middle-east country funds.
