The reason why this difference is important is because tranportation dominates oil use, more than 50 % of all oil is used in transportation. Also there are easy, cheap alternatives to oil in all sectors where oil is used, except in tranportation.
If we solve the transportation issue we would never ever need a single drop of fossil oil again. _________________ Peak oil is not an energy crisis. It is a liquid fuel crisis.

Starvid has a most important point when he says that peak oil is not an energy crisis, but a liquid fuel crisis. At first, you might say this smacks of the cornicopian view of Huber and Mills in their book "The Bottomless Well", where they say all the energy we'll ever need is all around us. We are not using up energy, it is merely changing form - from matter to heat to vapor back to matter and on and on. And according to the 1st law of thermodynamics, energy is conserved. We just need to be technologically clever enough to catch energy transformation in ways that are useful to us. But my response to that is that, historically, technological innovation tends to come along in quantum leaps in the grand scheme of things. And, while 5 or 10 years is a but a blink of an eye in that grand scheme, it is a very long and dangerous time atop Hubbert's peak. We get our electricity from coal (50%) and nuclear (20%) and natural gas and dams. Over 70% of oil goes to transportation fuel. So the Arab ATM of oil could cut us off next week, and we would still have all good life electricity gives us. We just couldn't get around. That's the way it happened in the '73 oil embargo. We had plenty of light to wait in gas lines by. The crisis we are entering is indeed a liquid fuel technology crisis. If we had developed gasoline from coal the way Presidents Carter and Ford started to 30 years ago, we would now be using less than 30% of the oil we are now using, and there would be no peak oil crisis for many, many years. Now there has to be a panic rush into coal conversion and other liquid fuel technologies that is going to be dicey for many years, but hopefully successful. That's not impossible. Hitler did it when the Allies cut off his oil imports. About half the fuel used by Germany's immense war machine was made from coal! And with 65 year old technology. Something similar could probably be done in 2006 America but for the wall of stupidity it faces in our governing bodies.

Welcome to the forum, netfind.
Conservation law is valuable only for the understanding of the physics of energy. This reference to 'conservation' should not be confused with the typical term for 'conservation' that means to preserve. When energy is conserved into ambient heat (which is where all energy ends up), it is conserved in terms of the 1st law of thermodynamics. But it is lost [forever] as useful energy to us (it is not conserved for human activity). The technology for converting ambient heat into useful energy is impossible. That is the 2nd law of thermodynamics (aka entropy).

That is the name of the game, for sure. It sounds so easy and it has been due to fossil fuels. But the problem is that there does not seem to be a technology that can transform energy at the same quantity and quality as oil & gas. Remember, fossil fuels aren't there because of technology. Other forms of energy exist at huge quantities, right in front of us. Hurricane Katrina had more energy then we can use in a year globally. But being able to control it is something no one can even conceive. Oil gas & coal is like a bunch of hurricanes contained in jar by the graces of Mother Nature.

The transportation issue is solved, but politics/greed is the main reason the solutions haven't been adopted.
Actually, there are CHEAPER alternatives in some areas of transportation than oil, BUT they also are low in resource consumption, thus low in cost, low in revenue and low in profits. Due to this, it is against the self interests of the auto industry to use them...
For instance, a gallon of gasoline contains about 33,800 wh of energy. It will allow an efficient midsize gasoline car 30 or so miles of travel. That same 33,800 wh put into a battery could take that same car more than 150 miles if it were an electric car. We don't need to store the energy equivalent of a tank of gas in an electric car, the energy equivalent of about 1 gallon will suffice, provided aerodynamic efficiency is improved.
The electric car is much cheaper to run than an equivalent gasoline car. Aside from periodic battery changes, it is maintenace free, and when you factor in these battery costs, it's still cheaper to run than a gas car so long as gas is above $1.50 a gallon or so. NiMH and Lithium batteries are estimated to last over 200,000 miles in an automotive application as well, but for the NiMH an oil company owns the patent and refuses to produce them for a traction application using solely battery power(Ovonic NiMH: 1,750 cycle life to full discharge and lasts longer with shallower discharges, 70 wh/kg specific capacity, $.150/wh storage in mass production) and for the lithium, since no one is mass producing electric cars, prices remain prohibitevely expensive(Mass production for automotive application would bring a lithium battery pack cost to around $7,000-10,000 or less, depending on efficiency of car and desire for 150-200 miles range. 400 cycle life to full discharge, 5,000 cycle life to 20% discharge, 160 wh/kg specific capacity, $.250/wh storage in mass production).
A midsize electric car without careful attention to aerodynamics(perhaps comparable to a Ford Taurus) would consume 250-300 wh/mile of energy at highway speeds, less in the city. A small sports car would use about 130-180 wh/mile at highway speeds, large SUV about 400-500 wh/mile.
Electric motors need no maintenance and last 500,000 miles on up and an electric car, provided it has a properly designed chassis and body, can thus last more than 30 years. A typical gasoline car now days lasts about 15 years and 150,000 miles or so.
Keep in mind a typical gas car has about $.05/mile in maintenance costs while an electric car's maintenance costs without batteries factored are 1/10th that due to a need for brakes and tires and such.
Gas is currently about $2.20/gallon in the United States, higher in everything else.
Do the math.
You will find that electric cars give you more for much less, BUT much less of your money will go to the auto industry as well. That's why they aren't making them! Add in the fact that the oil industry doesn't want to lose the 40% of their market that automobile fuel accounts for and you can see why they spent so much lobbying against the electric car as well.
Further, if we build an extensive mass transit system in nations that don't have it, focusing on light rail for city transport and high speed electric rail to replace an airline industry that can't stay afloat without a massive corporate welfare scheme courtesy of Joe Taxpayer, people won't usually need cars!
Electricity can again solve our transportation woes, provided we are willing to generate more of it using renewable resources that won't deplete.
However, the airline industry doesn't want high speed rail to compete in America, and always lobbies to kill any projects before they ever start construction. The auto industry HATES mass transit such as electricfied trolleys for cities, because if people don't need cars they won't buy and use them nearly as much! America had a very extensive light rail system that was bought by the auto industry in the 1940s and dissassembled to force people into requiring a car.
The solutions exist, they are viable, they are proven to work better than what we have today. However, being the doomer I am, I don't think we'll get around the politics in time and implement these solutions pre-peak. If these things aren't at least in the early adoption stages at the start of the production peak while being simutaneously scaled up, we are in for a world of hurt. _________________ The unnecessary felling of a tree, perhaps the old growth of centuries, seems to me a crime little short of murder. ~Thomas Jefferson

Hey I like electric vehicles myself and am a total convert. I will buy an electric scooter in the spring (see my avatar).

But call me when I can buy a midsize elctric car for $25000. Or even a small one.

That day will come if either of the following happen:
a) The auto industry are forced to mass produce them
b) The small businesses willing to make electric cars get a huge break from government regulations so that they don't need to hand build their cars
The big players in the auto industry are not going to do it on their own, despite the viability of the technology.(One notable exception: Mitsubishi will build them and sell them in Japan at around 2010, IF the government uses taxpayer dollars to keep the profit margins of the cars as high as a gas car to make up for an electric car's lack of maintenance.)
If I were a politician, I'd be hammering the electric car issue, the mass transit issue, peak oil, and alternative energy like crazy. The public needs to know about the consequences of peak oil and WHY nothing is being done to decrease the severity of its effects BEFORE peak oil's nasty effects show themselves up in society. _________________ The unnecessary felling of a tree, perhaps the old growth of centuries, seems to me a crime little short of murder. ~Thomas Jefferson

What do you mean by "hand build"? Does the government regulate the hand building of EVs? That sounds abserd.

More like without having the millions of dollars needed to pass a government crash test, small companies are restricted to having their vehicles registered as "special construction vehicles" and other similar designations like people do with kit cars, purpose built road-legal race cars, and fully custom hot rods. There's a catch: the states limit how many of those "special construction vehicles" are allowed to be built registered each year. In California, for instance, the limit is 300 cars per year for the *entire* state, including those who custom build and register their own cars regardless of whether they are a business or not. _________________ The unnecessary felling of a tree, perhaps the old growth of centuries, seems to me a crime little short of murder. ~Thomas Jefferson

"dub_scratch" - I agree with you on the practicality of technology saving us from the fossil fuel depletion problem (I was just presenting the cornucopian mind set of The Bottomless Well). Huber and Mills seem to think that we will simply take technology to the very limits of the 2nd law in a decade or so and come up with near magic ways of capturing nature's other gifts besides fossils - hydrogen, the ocean bed nonfossil goodies, what have you (they don't deal with trivial pests like Hubbert in their book). I'm not saying any of this new technology is impossible, but not likely in a decade and in enough QUANTITY to more than replace the highly pressurized, water injected flow rates of nature's nearly perfect energy source. Our energy policy should have been an emergency program to replace oil derived transportation fuel with coal derived fuel 30 years ago to give us much added time to gradually replace the other 20% or so of oil usage with other things. We really started to do that, then oil got cheap, Reagan, a cornucopian, was elected, tore Carter's solar panels off the white house, and let his normally good belief in free markets tell him that the free oil market would fix any real problem we had with energy. So we had the Asleep-At-The-Wheel energy policy for the next 25 years.
