No **** sherlock
, but the financials are the same, Oil is not as expensive in real terms as many are lead to believe by the popular press, and to a degree, the Oil Industry, the latter having a vested interest in the price of crude Oil.Fuels are an easy example to show the discrepencies as everyone understands this, some of the ways oil is used for other industries is not clear to the majority of people so the understanding may not be immediate to them.
You're quite correct, in fact, it's cheap, but this will change as the demand increases, while the supply cannot keep pace. Though that wont deal with the reckless destruction of forests as a way of providing "green" fuel form "sustainable" resourses.

Oilman, the supply of Oil is able to keep pace, even with the damage to the US and Iraqi fields.
The Saudi's run their fields at about 80% capacity, the North Sea runs at about the same. Mexico runs at about 70% cap, and Russia runs at an average of about 60% cap with less than 10% of potential reserves being utilised.
A friend of mine works in the Industry and has worked worldwide on Geophys projects, drilling rigs (exloration and utililisation) for the best part of 40 years. He is currently in a senior management position within an exploration arm of a certain Anglo Multinational. H said that from his knowledge he cannot see Oil reserves running dry for at least 100 years once other fields are tapped into.
He said Africa, parts of India, The Far East and inland Australia are awash with Oil, it is simply a bit more logistical to get it out so it is the easily accessible reserves that are being plundered now, but when these ones do start to diminish, the Oil companies will soon start to exploit these other known reserves and ones that have yet to be found.
Currently there are a number of Geophys projects being undertaken in the Med, Black Sea, Aral Sea and Hudson/James Bay, around 28% are expected to return positive results, meaning economically viable. These are simply ones that have been announced for staffing purposes, he knows of more than 100 such projects around the Globe that are expected to start within 24 months with similar returns.
As I said, there is a lot of hype out there, much of it from Governments.

So what's coming out now is cheaper to get at, when that's gone, the other will be more expensive.
As I understand it, the oil fields are not pumped at full capacity because it reduces the total amount of oil that can be recovered. There is a difference between maximum and optimum.

There have been no major oil discoveries since the 1960s.

"Can't We Just Explore More for Oil?"
Global oil discovery peaked in 1962 and has declined to virtually nothing in the past few years. We now consume 6 barrels of oil for every barrel we find.

Well he was wrong. Australia is a net importer of oil. If they were really 'awash' that wouldn't be the case.

Sorry, but biofuels are just waffle:
<SNIP>
"What About Biofuels Such
as Ethanol and Biodiesel?"
Biofuels such as biodiesel, ethanol, methanol etc. are great, but only in small doses. Biofuels are all grown with massive fossil fuel inputs (pesticides and fertilizers) and suffer from horribly low, sometimes negative, EROEIs. The production of ethanol, for instance, requires six units of energy to produce just one. That means it consumes more energy than it produces and thus will only serve to compound our energy deficit.
In addition, there is the problem of where to grow the stuff, as we are rapidly running out of arable land on which to grow food, let alone fuel. This is no small problem as the amount of land it takes to grow even a small amount of biofuel is quite staggering. As journalist Lee Dye points out in a July 2004 article entitled "Old Policies Make Shift From Foreign Oil Tough:"
. . . relying on corn for our future energy needs would
devastate the nation's food production. It takes 11 acres to
grow enough corn to fuel one automobile with ethanol for
10,000 miles, or about a year's driving, Pimentel says. That's
the amount of land needed to feed seven persons for the
same period of time.
And if we decided to power all of our automobiles with
ethanol, we would need to cover 97 percent of our land with
corn, he adds.

Help me to remind me to get you an introduction to the crew at Nedalco, I'm sure they will be delited to educate you on how they produce ethanol for over a century now.

And this is where he goes wrong: bioethanol is made out of LEFT-OVERS from crops after all the edible bits are taken out.

The left overs would be a tiny amount compared to what is needed.
We are not short of fuel. What we are short of is CHEAP fuel.
We have something like 20 million cars and a load of power stations that need energy. A few left-overs isn't going to sort it.
joe
Sorry joe. It's not a FEW left overs we're talking about here.
It's ALL the left-overs of beet, corn, rice, vegetables, you name, they take it.
