What I see here in Utah, we could take 60% of the traffic off the road if we removed one element.
The big car with one person driving 50 to 75 miles each way to work, we have too much of this here.
Our government makes us do it, we have public transportation and when I ask people, "Why don't you ride the bus or train?"
I get a good answer, It is cheaper for my Parts guy to drive his 8 mpg 1 ton truck than to ride the train, it is cheaper for my son to drive his grand AM than ride the bus.
Here is why, My government taxes me, they take the $$ and build big freeways and highways and expensive traffic signals and so on.
What if? What if, instead, take the $$ and give me subsidized Trains and Buses, AND bicycle lanes, then we could ride.
Use the labor force to build smart ways to get around. I need to add, bicycle travel in Utah, is ,,,,a car dodging exercise, and freeways dominate town to town commute.

That is pretty much USA everywhere outside of metropolitan areas. I was watching a show on the History channel on the history of freeways and according to one of the DOT's study, traffic jams cost American consumers $60 billion a year in lost productivity add that to the $164 billion in the cost of car accidents and you could fund one helluva mass transit system. However it isn't going to happen until driving becomes cost prohibitive and grossly inconvenient. One way would be to just stop funding roads for a while...

If we can get away from the idea that "automobile" = "several tons of metal" we might be in with a chance.

Taking very simplistic figures, if a single person weighs 100kg and their car weighs 900kg then 90% of the energy used is to move the metal box with only 10% being used to move the occupant. Turn that very light 900kg car into a 1900kg SUV and now only 5% of the energy used transports the driver.

For as long as SUVs weighing several tons use the same roads it's easy to see why people don't want to use lightweight vehicles - if I'm going to be involved in a collision I'd rather be the one in the solid metal box - but at the same time if we could strip away a lot of the metal we could end up with vehicles that can get around at a sensible pace and use energy far more efficiently.

One beauty of a bicycle is that it weighs so little. So instead of needing an engine to transport my 100kg frame within a 1400kg car, I can use my legs to transport my 100kg frame on a 15kg vehicle. Now somewhere around 85% of the energy used is transporting me - the vehicle represents a small part of the energy and so a much less powerful engine will work just fine.

It all comes back to the equation F=ma. If we can reduce m then much less F is needed to produce the same a. And there's a lot of scope to reduce m when we're starting with monstrous great SUVs.

And thus, we get to the bicycle, one of the most efficient machines ever devised. I for one would be quite happy with a small, 2 person, tadpole trike layout electric vehicle. 2 wheels driven at the front, light weather shell.

Yep, as long as it has a decent range, fast recharge and weatherproofing it can work. One big trouble with electric vehicles is the time it takes to recharge - if I want to drive a long distance it doesn't work if I can only do it in 100 mile chunks and then stop to recharge for 12 hours.

That said if we used the existing internal combustion engine in a very small and light vehicle we'd be able to get very respectable fuel economy.

Yes, though i have great hopes that we will soon have batteries, or hypercapacitors, that will permit such fast charge, and better range as well. The infrastructure will take time to change though.There will be some interim technologies, we are seeing some of them now. We will see some small vehicles which are purely electric drive, but with a generator running at very high efficiency levels. Several of these interim solutions will appear, and some will fall by the wayside as better, or more suitable technologies come on stream. The next few years are going to see a huge number of solutions proposed, it will interesting that's for sure.

If makers could standardise their batteries I can see filling stations being partly or entirely replaced with battery sellers. A new battery for one price, or trade a dead battery for a fully charged battery for a much lower price. Just like filling up with gas - pull in, a few minutes stopped, pay your money, and you're good for another 400 miles. Then the filling stations could have whatever provision they needed to recharge them.

The big difference would be that if you ran out of power you could plug it in anywhere you could reach (or use a portable solar panel, or whatever else).

There is someone talking about this, no link at the moment, but memory tells me it was in conjunction with Renault? The disadvantage is that cross company standardization is a hard sell these days, the vertical silo approach is all the rage.

If the cost (1/EROEI) is too high, we don't survive.

And just because the internal combustion engine is inefficient, don't take that to mean that even gross energy from renewable resources can even begin to approach the amount of energy currently extracted from oil in conventional automobiles, etc.- they can't.

As for net gain- of course renewable sources pale in comparison to the EROEI of fossil fuels. While estimations are difficult to construct, optimistic estimates of returns on solar power (which is the best renewable source known) is 10:1 [1]. More pessimistic estimates are more like 1:1 [2].

Biofuels: even if all of the arable land in the United States (including that which currently supplies, you know, food) were devoted to supplanting gasoline production/consumption, we would not scratch the surface of current use [3].

Again, think about it. Fossil fuels represent over 100 MILLION years of compressed, stored sunlight, graciously bequeathed unto us courtesy of the Carboniferous Period, 350 million years ago. It is a very, very potent source of energy. If you think of it in terms of drugs, fossil fuels are like heroin, to renewable energy's sugar pill.

I'm not saying we should not transition to every extent possible to renewable energy- we don't have a choice. But when we do, the current energy consumption rates CANNOT be sustained. Automobiles cannot exist in a system based on renewables- not even what is known as a totally 'solar powered' automobile. Trace the origins of that solar car, and a hell of a lot more energy went into building/maintaining the car, and the infrastructure supporting it, than will ever be retrieved from it over its lifetime.

We are going to have to downsize, in more ways than one. It is estimated that every fourth person on the planet is here because of petroleum/synthetic-nitrogen based farming[4]. If true, how we will deal with the peak of fossil fuel production is a tough pill indeed. Personally, I think part of the answer lies in getting smart, and fast, about organic farming and ecologically harmonious food production.

Everything is inextricably linked to everything else, but I can't reasonably state that No. 5, 1948, which sold for ~$150 million, has the same amount of energy as ~40 million gallons of gasoline because they both have the same cost. The cost/value of something includes any embodied energy costs, but it is not based on only embodied energy costs. If someone wants to show that something has a greater EROEI than something else then they need to look at the energy inputs alone, and should also to use comparable energy sources to avoid apples/oranges situations.

And yes, renewables can certainly approach the gross energy used in automobiles via oil, although they don't need to. If you're going to cite sources that's good but I need more information that just a last name and a year in order to determine if they're decent.

AFAIK most batteries can take a very fast charge, although depending on the type it's not very good for them, and it's mostly infrastructure that's lagging behind. Even older NiMH cells can take a ~20kW charge no problem, which implies it would take about an hour to get to almost full (getting to full takes a fair bit longer) on something w/ the same size pack as a Leaf.

I don't see what the price paid for a painting has to do with 'cost', in the context of this discussion. Or are you trying to say that money cannot be overspent? All due respect to Jackson Pollock and art aficionados, what is the value of a painting to a society that is hungry and must find a way to feed themselves?

There are factors other than market prices which enter into the true costs of energy. An obvious example is convenience. For example, liquid energy sources are more convenient, and will continue to be used for transportation-- even if they cost more than an equivalent amount of coal derived electricity.

However, EROEI has to do with energy, not cost. A Pollock painting can cost the same amount as a lot of gasoline, but just because something has equivalent or higher costs doesn't imply it's EROEI is higher than the cost of something else.

In terms of your claims, could you provide links to specific information available online, or at least provide the specific sections of the books you're citing along with their sources?

You are correct-- but when we talk about the 'convenience' of transporting liquid fuels, what we are really talking about is the cost. It is less expensive to transport liquid fuels because you can use pipes and other means unavailable for other forms.

lyeinyoureye,

Off the top of my head, you can start getting information about EROEI from Greer's book as early as pages 15-19. McKibben's book, pages 57-59, and pages 160-190. But honestly, McKibben's and the other books I listed are full of this kind of info from beginning to end. I could go flipping through the pages of other books to provide specific page numbers for you, but I don't feel like it.

Heinberg, McKibben, Odum, Deffeyes are among the names you'd be interested to know if you want to learn about energy and its cost, ecology and sustainability. These people have been studying the energy problem for a long time and know a lot about it. Of course there are books that provide counterpoints as well. I could recommend more sources & books, but I'm sure you can find them yourself.


Edit: Also, you may be interested in any of the publications of Dr. David Pimentel, professor emeritus of Ecology and Evolutionary Biology at Cornell University. Some of his pubs are available on the web. His position is clear: alternative energy cannot replace nuclear and fossil fuel sources, and society is going to have to scale back its energy consumption rate. Even with wide adoption of renewable sources of energy, downsizing is not an 'option', it is an unavoidable eventuality.

If we ride our bikes and use the city bus, (I WISH we had commuter trains!!!!!!!), we can actually afford to "ENJOY LIFE" a bit and actually have a little FUN, (I know here in the USA, that's a crime, unless you have LOTS of money!).

Can we purchase a car, SURE, some used up beater, paying 24% interest and insane cost's of full coverage ins. For us cars are a thing of the past, unless we hit a lotto, LOL. I really admire YOU all who are "Car Free" for the cause, for us, it's the only way we can LIVE, jmho, ymmv.

Where are they getting their information? It seems to conflict with the majority of existing sources, and some comparisons are completely apples/oranges.

"We will not be banning cars from city centres anymore than we will be having rectangular bananas."

Typical Brussels bashing from the British refers to a story from years back that the EU was trying to standardise fruit and veg.

As I posted before this report is aspirational.

Odd... from my reading of the story, I inferred that he had no real say in what was basically a municipal decision. Kind of weaseled out of an answer...

He being the UK transport minister. He said it (the EU Commission) should not be involved in individual cities transport choices.

The EU Commission is not elected. The UK government is and so are the individual city authorities.

I'm not making a point about the merits or otherwise of these proposals just trying to explain the political background to a U.S. audience.

4 hours maximum on my recumbent trike. More charging time NOT advised. 3 plain old lead acid batteries (motorcycle battery size- 36V) with a dinky (as in small) lithium battery charger. Usually full power charge 2 hours and top it off at slow charge. It is nothing fancy- off the shelf stuff!
