corra said:there is not enough factories to make solar panels on a big level, also there is not enough demand to justify making more factories.
when peak oil hits it will take a long time to get the factories up and running to supply the solar panels. not to mention the raw materials needed which is already in short supply.
The source i have this info from is matthew simmons.
If you do not know who he is i suggest you watch the "Crude awakening" documentary covering peak oil and its consequenses.
I've heard that figure before and it is simply a lie spread by radical environmentalists (I can't remember where it came from - perhaps Greenpeace). They choose simply wrong assumptions for every part of their calculation. Real nuclear engineers predict we could go for hundreds, perhaps thousands of years using current technologies and reasonable projected growth in energy needs.corra said:nuclear power taking over as the main power delivery system would burn through our remaining uranium in 20 years...
http://www.americanenergyindependence.com/uranium.htmlIn summary, the actual recoverable uranium supply is likely to be enough to last several hundred (up to 1000) years, even using standard reactors. With breeders, it is essentially infinite. Hundreds of thousands of years is certainly enough time to develop fusion power, or renewable sources that can meet all our power needs.

Well, no, by my calculations 10,000 nuclear plants would roughly equal the world's current energy usage from all sources (447 quadrillion btu in 2004). Somewhere around half of that is oil and assuming the peak oil prediction is right, we would have several decades to bulid them as oil production falls.not to mention that to replace oil we would need 10.000 of the biggest possible nuclear plants.
Yeah, it does matter because oil is not going to simply disappear. That's not even what "peak oil" is about.wolram said:Does it matter, if you do not have it you can not make these things from it.

Does this help? If the following is correct, then the answer is around 10% or less depending upon how that 10% is split out.russ_watters said:What fraction of our oil is used to make plastics and other manufactured goods? Is that really a significant issue?
http://www.eia.doe.gov/neic/infosheets/petroleumproducts.html"DOE said:Fuel products account for nearly 9 out of every 10 barrels of petroleum used in the United States.
How very significant? This link puts it in a category along with petroleum jelly and says the entire category represents 0.3% of products and uses.Chi Meson said:A very significant use of petroleum products, I have recently learned, is crop fertilizer.
corra said:Within 2-10 years all these things will have happened to this planet.
1: Crash of the american dollar.
2: Worldwide recession.
3: Famine and disease catastrophes in 3 world countries.
4: Rescource wars in the middle east to secure oil rights.
5: Israel going into Iran backed by the U.S (under the exuse of the nuclear programme)
6: Suburbian ghost towns will crop up all over the United States as people move back into cities or out to towns and villages.
7: Indentured servants will be brought back in the us due to the large amounts of people not being able to pay their mortgages when recession hits. (new law passed recently allowing this)
8: The end of the green revolution.
9: Massive increase in CO2 pollution due to increase in coal plants.
10: Un-employment sky rocketing in the U.S where 15% of all jobs directly and indirectly cater to the automobile industry.
All this WILL happen and for 1 reason. Peak oil.

Has all you need to know about peak oil and if you read the paper you will be shocked, depressed and enlightened all at once.
It is a must read if you have not heard about Peak oil before.

OK. This is much more similar to the numbers that were running through my head. Corra, you should probably try to find some new sources, especially if they are trying to use lies from radical environmentalists.russ_watters said:I've heard that figure before and it is simply a lie spread by radical environmentalists (I can't remember where it came from - perhaps Greenpeace).

I think the 20 years thing does allow for mining more from known reserves, but it also requires a once-through fuel cycle, which is sheer stupidity. That's like filling up your gas tank, driving 5 miles, emptying the rest of your still-good fuel into into a waste container and filling up the tank again.Chi Meson said:Believe me, I think through it carefully before I agree with Russ.But...
I agree with Russ on the "20 years of uranium" myth.
The "20 year supply of uranium" comes from: IF we replace fossil-based electricity with fission-based electricity, and IF we continue to use energy at current rates, then our national uranium RESERVES (the stuff already mined, refined and set aside for future use) would last 20 years. There's still more in the ground.
I have heard as much as 600 years of fission is probable. "Infinite" sounds a bit high though.
A very significant use of petroleum products, I have recently learned, is crop fertilizer. As I said before, we are heading for interesting times this century.
jimmysnyder said:How very significant?
Chi Meson said:Not that it is a significant percentage of total use of petroleum products, but significant in the way it is used. Petroleum-based fertilizer has provided our agri-business with very cheap fertilizer which will be not-so-very-cheap in the near future. The rising prices of oil byproducts will have a greater effect than we at first imagine.
http://www.fertilizer.org/ifa/statistics/indicators/ind_reserves.asp"ifa said:The main fertilizer raw materials are energy and hydrocarbon feedstock, phosphate rock, sulphur and potassium salts. It is unlikely that there will be a global shortage of any of the raw materials for the manufacture of mineral fertilizers in the foreseeable future, apart from temporary tight supplies due, for example, to an unexpected surge of demand resulting from a loss of production (for example from the flooding of a potash mine).
