Electricity, none of which comes from oil.
You are proposing that the energy currently derived from fossil fuels be replaced by energy delivered via electricity. How is this extra electricity to be generated - what is the energy source?

So where are all the electric cars?That statement forgets the enormous progress battery capacity has made in the past 20 years, as well as the drop in the cost of manufacturing.
Why would we need to massively expand our infrastructure?
You're confusing transmission infrastructure with distribution infrastructure.Even present day gas stations have electricity lines going into them.
I'm not sure what the phrase "more powerful" means in this context.I find it interesting that you talk about a lack of cheap energy, when in fact we have a source of energy that is so much more powerful than any fossil fuel: nuclear fission.
Our biggest problem is transportation, fortunately we have electric cars coming onto the market now. For daily commutes battery power is enough. Charging stations are easy to build. You'd be surprised how quickly things can scale up thanks to the industrial revolution.

7 gallons of oil is needed to produce 1 standard vehicle tire.
Because we're talking about massively increasing our use of electricity.

It's a bit more complicated than that. Part of the reason that electric vehicles failed to achieve commercial success in the past is the same reason that oil prices were low: one was heavily subsidized by government and one was not. (The dismantling of much of our rail infrastructure was also part of that mix).Here is one, with more on the way in the coming years.
Thing is the oil price didn't get high enough until recently to justify making them.
Is it? Are you sure it doesn't actually cost about twice as much to build a mile of high-voltage transmission line as it does to build a mile of highway?You know what amazes me? We were able to build a vast freeway network 60 years ago, but today people keep saying we can't upgrade our electrical grid, which is considerably easier and less expensive.
Dude. I specifically said that I am NOT saying that:Very well then, so you're saying we can't do this?Dymanic said:Because we're talking about massively increasing our use of electricity.
I can understand why you might not want to take the time to slog through the entire thread, but would it be too much to ask that you at least read carefully the posts that have been made since you joined the discussion? If you were to review the whole thread you might see that I can be a little touchy about having words put in my mouth. (While we're at it, be a little careful with the quote feature too; you used it to quote JJ above, but then switched to unattributed quotes by me, and that can create confusion).I'm not saying that converting our transportation sector to rely more on electricity than on fossil fuels is impossible, or even impractical.
Until we start putting nuke plants under the hoods of our cars, I don't see how that helps.Means vastly more energy dense. 1 kilogram of Uranium has the energy equivalence of 1000 tons of coal. Now that is power.
What I am saying is that the undertaking we're considering here is massive, and the costs will be massive, and the current investment interest is nowhere near strong enough to support it, and the political will to support it through government subsidy isn't there either. We can do it, and we must do it, and the problem I see is that it doesn't look like we are doing it (aside from some token gestures pointed more or less in the general direction).

Apparently so, considering the ease with which it is accepted that as soon as we begin talking about a transportation infrastructure powered by electricity it may be assumed that we're talking about "electric cars".Are cars really so essential?

Quick answer: Yes.
Edited by Tricky:Edited for quote of modded post.
Consider where you live, and where you work. The average American commute distance is 16 miles. (one-way distance, figures from 2005), which is impractical by any non-mechanical means. There is simply not enough railway infrastructure to take up the slack (there are more than ten times as many paved road miles as railroad miles). Even converting most commuters to take a bus would require massive infrastructure investments -- and that would still probably involve fossil-fuel-driven vehicles.
In the long run, we could probably restructure our lives (and our zoning systems) to have something other than the miles and miles of bedroom communities surrounding a commercial core, but it took something like fifty years of urban planning to get to where we are, and it's likely to take another fifty to get to someplace else.
So for the next fifty years, cars are pretty much a necessity, yes.
However there is probably scope for a significant reduction in car usage. I only have data for London, which might be unlike the US, but even so the figures shocked me
The median distance for car journeys in London is 2-miles. 80% of car journeys are under 6-miles.
According to the graph of this book (page 15 google books link here) about 30% of car journeys are under 1-mile.
Over a couple of miles, I'd have thought that in good weather, a healthy individual would have a shorter journey time on a bicycle than a car (if you add in the time to park and walk from the car).
Quick answer: Yes.
Slightly longer answer: Yes, lackwit.

Uh huh.
tl;dr

If cycling could be made less unattractive, it could make a significant difference to the number of cars on the road in densely populated cities. (Hey - for distances under a mile, walking is not onerous).
The numbers will be different in the US. In some US cities it’s difficult to even buy groceries without traveling several miles of the freeway and “a short distance from work” means 20 miles on a freeway.
Bad urban planning is the single biggest single obstacle the US faces in reducing its energy consumption. Far to much of the country is based entirely on automobile traffic, and IMO it’s going to be a significant competitive disadvantage over the coming decades.
I agree. There will always be some uses of oil that would be very difficult to replace with anything else, though natural gas is an adequate substitute in many applications for which battery power just doesn't quite cut it, as well as being a much easier conversion to make (and the point of peak natural gas production really is so far in the future that we don't need to worry about it yet).Batteries to power local personal transport is one thing, but for the life of me I can't picture batteries that will power a combine-harvester churning away all day over rough ground in the extreme distance. Nor massive quarrying machinery, nor chainsaws way up in the hills, nor heavy deliveries to any remote spot (Ice-road truckers, anybody?)
If our future way of life is not to be utterly transformed then there will remain a requirement for fluid fuel of some kind.
drkitten,
It is impossible for consumption to exceed production (including strategic reserves), but I would argue that it is possible for demand to exceed production.
Not in any meaningful sense. Unless you're talking about "demand" as meaning "how much oil people would use if it were free," in which case "demand" for anything is presumptively infinite.
In which case the demand for everything (which is infinite) exceeds the supply of anything (which is finite). Not especially meaningful or useful.
By that logic, isn't fammine impossible?
If demand for food exceeds supply, the price would rise until the demand fell to meet the new supply?
I would argue that our current way of life requires a certain amount of oil usage, and that if supply falls below that, then there would be problems. I am not denying that some demand is elastic, but I would argue that some isn't... Or at least is not very elastic.
I was referring to getting our vehicles off of fossil fuels to the greatest extent possible. Peak Oil is not an energy problem, it's a liquid fuels problem.
