So that makes him an authority on the capabilities of other energy technologies. k.
Carry on waiting for the end of the world.
Yes it does.

No it doesn't.Yes it does.![]()
No it doesn't.
You arrived at your conclusion via a logical fallacy.How's that sir/ma'am?
You arrived at your conclusion via a logical fallacy.
So then, how isn't he an appropriate authority?
Have you come up with any numbers showing that civilization is going to collapse once the oil runs out because renewable energy sources won't be sufficient? We're waiting eagerly.
And failing, because it's completely untrue.All forms of modern technology are petroleum products, something I've been trying to get across here for a while...
Fail right off the grid.
So, TFian, to sum up, oil and other fossil fuels make up a major part of our current energy infrastructure. Developing new energy infrastructure requires energy. Therefore it's impossible to develop non-fossil fuel based energy infrastructure.
Um...
Energy equivalent. Not oil.The construction of an average car consumes the energy equivalent of approximately 20 barrels (840 gallons) of oil.
This is an interesting one. Obviously, there is no overall shortage of fresh water in the world. One entire continent is covered in it to a depth of a couple of miles. It's also renewable.It's also worth nothing that the construction of an average car consumes almost 120,000 gallons of fresh water. (6) Fresh water is also rapidly depleting and happens to be absolutely essential to the petroleum refining process as each gallon of gasoline requires almost two gallons of fresh water for refining. (7)
Wrong link - you mean (9).The construction of the average desktop computer consumes ten times its weight in fossil fuels. (8)
Your links are out of sync.The production of one gram of microchips consumes 630 grams of fossil fuels. According to the American Chemical Society, the construction of single 32 megabyte DRAM chip requires 3.5 pounds of fossil fuels in addition to 70.5 pounds of water. (9)
That page isn't explicitly dated, but it's copyrighted 2002. Again, it's obvious just from the photo of the phone's insides that this is hopelessly out of date. No-one builds mobile phones like that any more.The Environmental Literacy Council tells us that due to the "purity and sophistication of materials (needed for) a microchip, . . . the energy used in producing nine or ten computers is enough to produce an automobile." (10)
Of course they're not. That would be absurdly inefficient.In his book "The Nine Nations of North America", author Joel Garreau explains in graphic detail just how much energy it takes to fashion a typical microprocessor: . . . microchips are not made one by one.
In 1970, maybe. These days 12 inches is standard.They are printed in a batch on a silicon wafer, say, four inches in diameter.
Quantify, please.Each time a layer of stuff is printed on this silicon wafer, the wafer must be treated so the stuff you've laid on will stay there. This process is achieved through the application of monumental quantities of energy.
This is flatly untrue. If the temperatures were ever "high enough to reach the outer limits of technology" the chips would become rapidly expanding plasmas and would be significantly less useful.In effect, as each layer of the circuit is laid on, the whole wafer is "baked" at temperatures sometimes high enough to reach the outer limits of technology (11)
Follow your own link (it's actually 13). The study came in for considerable criticism; it overstates the power consumption by a considerable factor because it's based on figures that were eight years old even at the time the report was produced.The Internet:
Recent estimates indicate the infrastructure necessary to support the internet consumes 10% of all the electricity produced in the United States. (12)
This is true.The overwhelming majority of this electricity is produced using coal or natural gas, both of which, as explained momentarily, are also near their global production peaks. (13) (14) (15) (16) (17)
Nope.Despite what others have said, solar panels and wind turbines REQUIRE petroleum and petroleum derived resources.
So?When considering the role of oil in the production of modern technology, remember that most alternative systems of energy — including solar panels/solar-nanotechnology, windmills, hydrogen fuel cells, biodiesel production facilities, nuclear power plants, etc. all rely on sophisticated technology and energy-intensive forms of metallurgy.
So?In fact, all electrical devices make use of silver, copper, aluminum and platinum, each of which is discovered, extracted, and fashioned using oil or natural gas powered machinery.
We do NOT use oil to refine aluminium. I hope you at least understand that.For instance, in his book, The Lean Years: Politics of Scarcity, author Richard J. Barnet writes:
To produce a ton of copper requires 112 million BTU's or the equal of 17.8
barrels of oil. The energy cost component of aluminum is 20 times higher.
You do understand that we don't use oil to refine aluminium, right? Right?Author Joel Garreau, in the same chapter of his book "The Nine Nations of North America" that was cited above, explains how energy-intensive the manufacture of aluminum is: The manufacturing of aluminum requires inexpensive energy as its most important raw material. It takes twelve times as much power to create a pound of aluminum as it does to make a pound of iron. A good sized aluminum plant uses as much power as a city of 175,000 people. (18)
Because this is cheap and convenient. We can recover, refine and transport uranium without any use of oil whatsoever. Using current, proven technology.Nuclear energy requires uranium, which is also discovered, extracted, and transported using oil powered machinery.
Using corn for producing biofuel is pure idiocy. Don't do that.Most of the feedstock (soybeans, corn) for biofuels such as biodiesel and ethanol are grown using the high-tech, oil-powered industrial methods of agriculture.
Nope.In short, the so called "alternatives" to oil are actually "derivatives" of oil.
Because it's cheap and convenient, not because it's necessary.Analyst John Michael Greer offers the following rather lucid explanation of this often over-looked relationship: . . . every other energy source currently used in modern societies gets a substantial "energy subsidy" from oil.
And returns - this is rather the point - vastly more power than was used in its extraction.The energy used in uranium mining and reactor construction, for example, comes from diesel rather than nuclear power
Actually, it does. We call them leaves.just as sunlight doesn’t make solar panels.
And a false premise allows you to reach any conclusion at all. Doesn't make the conclusion true.What rarely seems to have been noticed is the way these "energy subsidies" intersect with the challenges of declining petroleum production to [preemptievely sabotage] the future of alternative energy production in industrial societies. (24)
We have oil for the next hundred years, uranium for the next million, and sunlight for a few billion.Without an affordable supply of oil coupled with healthy and robust financial markets to capitalize the transition, a non-chaotic adaptation phase is unlikely as the raw materials and investment capital necessary to fuel such a large-scale transition will have evaporated.
What's the problem? I gave detailed reasons why you can't.
All forms of modern technology are petroleum products, something I've been trying to get across here for a while...
The construction of an average car consumes the energy equivalent of approximately 20 barrels (840 gallons) of oil. (4) Ultimately, the construction of a car will consume an amount of fossil fuels equivalent to twice the car’s final weight. (5)
It's easy to understand why we committed to crude oil early in the industrial game. Its energy density, EROI, and convenience of combustion are irresistible. It's small wonder, then, that we developed an entire civilization based on fossil fuels.
Ultimately, all this points to a future in which we will be energy poor because we've used up the storehouse of cheap, convenient energy.

It will be interesting to see how long it takes to build the infrastructure for that renewable 7% energy--34% of which is hydro--to cover the 80 plus % of fossil energy the US uses per year. It took 100 years to develop the petroleum industry. The 1% solar will have trouble ramping up.

TFian, your argument basically boils down to this "One person that I consider to be an authority says that industrial civilization will collapse because we are running out of oil and all alternatives have major disadvantages that will cause them to fail, while attempts to improving efficiency through technology will also fail."
On the other hand, most authorities on the subject disagree with him. So, if we find the work of truly understanding the subject to be too much and are forced to only listen to authorities on the subject, we're forced to reject the 21st level Druid simply on that basis.
On the other hand if we go into the issues and look at them specifically we see:
- There is enough fissile material in the ground to support a fission based energy economy for centuries based on breeder reactors, and there is no insurmountable difficulty with breeder reactors, particularly as the price of energy rises and people are forced to make the choice between this and going without.
- There is enough uranium in the ocean, which can be harvested cost effectively, though not competitively with today's energy prices and the cost of mining currently known terrestrial uranium sources, to last for hundreds of thousands of years.
- Solar power can be collected and used, and there is enough of that by itself to power industrial civilization. And while it will be at greater cost, it will still be cost effective for maintaining manufacturing.
- There are still other sources of power, such as hydro and geothermal, wind, etc. which are proven effective. Are they the best solution? No, but they do work, and while relying only on them might mean our civilization would have to contract somewhat, it would certainly prevent the sort of collapse you are talking about.
- Increasing technology means we are able to do more for less. As others have pointed out, modern computers are much more efficient in terms of energy than their predecessors, and those were themselves more efficient than the technologies they replaced (like doing calculations by hand, using human operated switchboards, etc.)
Do you have any answer to any of these problems with your viewpoint, or are you simply going to assert without evidence that computers are less energy efficient that the alternative low tech methods, that all forms of energy generation not based on fossil fuels are not viable, that the uranium in the oceans mysteriously cannot be harvested, etc.?
Look it up.1 - How many breeder reactors are out there and working right now?
Look it up.2 - What are the environmental consequences of mining this uranium?
This was already shown to be wrong. The ArchKook has no idea what he's talking about.3 - While there's enough to power civilization when it comes to earth, we've only had very meager success harvesting it for practical applications. Sunshine is dilute, not concentrated, it doesn't have very much usable energy in, and therefore cannot power civilization http://thearchdruidreport.blogspot.com/2010/02/energy-follows-its-bliss.html
Tell that to Iceland.4 - Wind, Geothermal, and Hydro make out pretty minuscule energy returns.
These "gizmos" do things orders of magnitude more efficiently than anything human power can ever do.5 - Yeah but at what cost? Why do we need so many nifty gizmos? We did fine when we just used human power.
Look it up.

These are maps of the available solar energy in the US. There's a lot.
