What about electrification of rail all over the world, so that most rail traffic is electric now?
-Tom S
In 2006, 240,000 km (25% by length) of the world rail network was electrified and 50% of all rail transport was carried by electric traction. (my emphasis)
In 2012 for electrified kilometers, China surpassed Russia making it first place in the world with over 48k km electrified.[14] Trailing behind China was Russia 43.3k km, Germany 21.0k km, India 18.8k km, Japan 17.0k km, and France 15.2k km. By the end of 2015, China planned to have about 72k km electrified.

I don't believe in fate, in either direction.

I just did a quick google search ("electrified railroad world") and the first link which came up was a wikipedia article on railroad electrification:In 2006, 240,000 km (25% by length) of the world rail network was electrified and 50% of all rail transport was carried by electric traction.

If you didn't know this, then you should have typed it into google before reflexively rejecting it.
Germany uses electricity for the majority of its rail traffic. Almost 30% of that electricity comes from renewables now.

The EROI of solar energy collecting devices is low. If you have an argument with that take it up with Charles Hall, Pedro Prieto and Graham Palmer.

Ultimately, those products do not require any oil for their construction. There are obvious substitutes for every usage of fossil fuels. Those substitutes have already been developed, and no further technological development is required.
Fossil fuels are not some unique irreplaceable substance. They are ordinary chemicals. They have obvious substitutes, such as electrified transportation and renewable power. Even for the very few usages which really require a chemical combustible fuel (such as air travel), there are many obvious ways of manufacturing such fuels. For example, there are: anhydrous ammonia, dimethyl ether, alcohol fuels such as methanol, biofuels, and many, many others. It's also possible to use metal fuels, such as aluminum, magnesium, and others. It's also possible to manufacture natural gas and oil using renewable energy, using the Sabatier process or the Fischer Tropsch process. There are also many other alternatives being investigated and developed now. As a start, you can find more information about this here: http://en.wikipedia.org/wiki/Alternative_fuel
Fossil fuels are used because they're the CHEAPEST way of accomplishing certain things right now. That's the only reason. Fossil fuels are modestly cheaper than alternatives, that's all.
Oil will deplete gradually over more than a century. That is VASTLY more time than the economy requires to transition to alternatives. The economy ROUTINELY and AUTOMATICALLY transitions to alternatives as they become cheaper. This is an EASY PROBLEM for the economy to manage. This is something which the economy does all the time. Some things may become more expensive, but there is no imminent end of civilization because of peak oil.

Your glib throw away of the works I cited
You as usual discount the infrastructure and the various URLs I provided...
Your glib throw away of the works I cited ...I will no longer respond to any post of yours
Take NG, oil and coal out of the equation and all the fancy alternatives that you mentioned amount to basically 0.
Those alternative sources (sun,...etc)
1- will never pack the punch that we got from fossil fuels.
We will never again have such abundance of ready available energy to play with and such complex society.
Conclusion PO not necessarily the end of civilization but certainly a game changer.

Sunweb, I have already read all of the sources you brought up. We've been through this before. I've already read Hall and Preito's book, and provided a lengthy refutation on my blog, as you know. I have already pointed out the severe mathematical errors within that source. I have already provided you specifically with a wealth of other sources that reach a different conclusion. I'm certainly not "glibly throwing away" the works you cited.
If you seriously need a reminder of the sources I provided, here are two of them:
Behind the numbers on energy return on investment, Mason Imman, Scientific American (Vol 308, Issue 4)
EROI of crystalline solar photovoltaics, Johan Lundin, Uppsala University (PhD thesis), May 2013You as usual discount the infrastructure and the various URLs I provided...
sunweb, as you know, I am already familiar with those sources. I have ALREADY seen and responded to those videos. Those videos provide no support for your claim. You are making a MASSIVE logical leap by posting a video of glass production then concluding that civilization will soon collapse.Your glib throw away of the works I cited ...I will no longer respond to any post of yours
Sunweb, you are the one who glibly ignores sources and information. I have provided you with a step-by-step refutation and a wealth of sources, repeatedly. In all cases, you simply totally ignore it. When I post objections on your blog, you do not answer them. You simply refuse to answer any objections.
Your posts are of the "hit and run" variety, whereby you post the same single discredited source, over and over. When I point out the mistakes in it, or provide other sources, you suddenly say "I refuse to answer any objections" and then leave. THAT is glibly ignoring sources.
You've never once answered any objections. If you don't want to answer objections, that's up to you. But then your point is refuted.

Sounds a lot like Lovelock. You been reading him?
