$this->bbcode_second_pass_quote('', 'A')s someone who does efficiency work, increased efficiency means job cuts, not more vacation time. The problem is growth. Peak oil means the end of economic growth, which is what most of our economy is based on. Sure peak energy/materials means the system will have to be more efficient, but that means less jobs.
Greed at work. It doesn't HAVE to lead to that, but inevitably our large multinationals want to maximize returns.
As is obvious, unlimited growth is impossible. Either we can do things the responsible way by allowing what little resources will be available to stretch further, or we can keep propped up the current elite social class we have today at the expense of everyone else.
If our market were truly free, consumers would have already gotten their say with cheap wind energy, cheap to run electric cars, hemp for biofuels/plastics/medicines... But entrenched business interests and big government stalled these things to protect their profit margins, either through legislation or outright refusal to meet market demand.
Too bad.
$this->bbcode_second_pass_quote('', 'R')egarding windmills... Well, as they say windmills don't breed windmills. Though a car next to a windmill makes a great picture.
Perhaps not, but the materials they are made of are recyclable and they can produce energy that could be used in the construction of more windmills.
Realistically, our grid can handle up to 20% wind, factoring in that it doesn't produce reactive power and is only stable over vast areas of land. While the U.S. may have enough land to place windmills without encroaching on protected land to power itself many times over, it would never be able to make use of all that with today's energy storage technology. Large scale turbines are cheaper than coal, about $.03-.05/kWh compared to $.04-.06/kWh for coal, but are much, much less profitable. All of that mining, transporting, processing, and burning has profit margins lined into it. Therefore, less than 1% of our grid is wind, when we could be using a lot more.
$this->bbcode_second_pass_quote('', 'T')he problem with these wonderful technologies is that they cannot make up for sharp depletion curves and even sharper EROEI.
With conservation, it wouldn't matter near as much.
Wind turbines have EROEI > 25. Industrial hemp has EROEI > 2, needs very little fertilizers, no pesticide inputs, takes decades to deplete the soil(and can aid in restoring it from damage caused by previous crops), can be grown in almost any climate, make biodiesel for the equiavlent of $.60/gallon, and yields 300 gallons of seed oil per hectare per harvest.
Well to wheels, electric cars will consume about half the energy of equivalent gas ones.
Even a modest amount of hemp for biofuels would go extremely far if cars addressed aerodynamics and used diesel engines to get 80+ mpg without reducing the size or the acceleration capability of the car. Aerodynamic drag reduction and other efficiency modifications can be applied to gasoline cars as well. Google search the following:

*Daihatsu UFE-III (gasoline), 170 mpg, sub-compact
The typical American midsize sedan accelerates 0-60 mph 10 seconds, tops 115 mph, and gets ~27 mpg on gasoline. Considering the above and the fact that these fuel efficient designs are possible with a cost penalty under $2,000 in most cases(and some cases none at all), isn't that embarassing? With gas prices what they are, consumers clearly want vehicles like this!
Allow an extensive mass transit system as America had pre 1940s so that the car isn't a necessity, have long range EVs available for Americans to purchase, have 60+ mpg biodiesel cars, allow cultivation of cannabis for fuel, plastics, textiles, timber, and medicines, stop subsidizing wasteful factory farming so that more sustainable practices are again the most affordable option, use wind and biomass where it is applicable, build houses to use passive solar heating and cooling, stop letting the oversubsizied airline industry prevent high speed electric rail systems from being developed in the US for long distance applications, and we could literally cut both our oil and energy consumption by more than half without yet sacrificing living standards.
While not all of these can be done immediately, we could be getting started on them now and be in a very good position 10 years from now. But industry wants to maximize the flow of money from your wallet to their investors and government wants to mazimize the flow of money from your wallet to their bureaucrats, so they aren't going to help improve efficiency in the least.
$this->bbcode_second_pass_quote('', 'H')istorically painful shortages have happened in this country before. In 1973 US oil field depletion meant the end of growth for the US for that time. That is until we secured a new river of oil from the world market. Now that river is running dry and we are back in 1972 talking about windmills (again).
The unnecessary felling of a tree, perhaps the old growth of centuries, seems to me a crime little short of murder. ~Thomas Jefferson

$this->bbcode_second_pass_quote('The_Toecutter', 'P')ersonally, I think we are headed for the Mad Max future. The real rub is that it was all preventable, except for the greed of a very small and very wealthy segment of our population who stand to lose their vast profits if we go to a sustainable society.
I hear ya... And though I feel like disagreeing a little with your comment on the wealthy, drunk asinine Paris Hilton types are so not worth defending.
Also I think the oil quiz link posted today in another forum pretty well summed up the economic problems of Time and Scale facing us after peak. 1970's all over again, but with no end. Oil Quiz -

Something amusing about my efficiency work stuff (making a data systems department more efficient). Part of my last job was to eliminate my job... So you can't say I didn't get my just deserts!
$this->bbcode_second_pass_quote('The_Toecutter', 'C')opper and other metals may be getting scarce, but they are also recyclable and more is being found each day. Sadly, much of it is sitting in land fills as I type this.
Well, my thoughts on this... Copper is recyclable but most good copper is in use, you can't recycle something being used. The copper in landfills? Most landfills already sort and sell off any large scrap metal - a great way to buy discount roofing materials. And about the copper in the landfill? Well, there are small strands to be found, but this takes significant effort and has issues not present in high grade ore. Copper in landfills is contaminated with lead, coated with rubber and in small quantities. And IMO, not at all like a good copper ore. And as for more ore being found each day, I believe most large deposits have been found and are being exploited, like oil and gas.
But hey I'll tell ya The_Toecutter, I like your style, hope mixed with realism...
Something amusing, your user name makes me think of a bedtime story about a kid that pulls up a toe in a garden. Their family cooks it up. Then the owner of the toe comes looking for his toe repeating "where's my toe"... ..."It's here!!!" "Now go to sleep." And for some reason my wife doesn't like my bedtime stories.
