Based on today's info by larsb

Based on the info they have today, the trends they have in place, and the fact that they do this for a living, doing those projections is just WHAT THEY DO.
 
Many hundreds of thousands of people around the world do "projections" for a living and that is a valuable service to a lot of people.
 
No one can see into the future - but with the best info, it is possible to make an "educated guess" based on hundreds and maybe thousands of data points.
 
I'm sure some of those guys projected $4 gas in June 2008.

Projections are fine as long as the person wanting the projection is paying for it. I don't want the government using my tax money for WAG projections. Or polls where they ask 1000 people what they think and say it is a good cross section of 200 million voters. It could be erroneous projections that has run the price of oil beyond what it needs to be.

Don't get a big-head, but I'd trust your projection on the price of oil or gas in 2015, as much as this guy's. Why? Because the whole mathematical trend has broken down. There is no longer any relationship between if demand goes up 1%, oil goes up 2%.
 
Because we are now in an era where if oil goes up 1%, or supply goes down 2%, that may cause a 50% price increase which causes the economy to go down 5%, which then decrease the demand. But since no one can predict whether the price increase is 50% or 25% or 75%, no one can predict how the economy will go in this country never mind globally, and it just goes on and on. Throw in the uncertainty of the condition of fields in Mexico, the future of oil-shale, ANWR and other undrilled areas, and there's no way anyone will have a decent model.
 
These forecasters are simply doing these forecasts because they used to, and they get paid for it. If any of these guys actually knew what they were talking about, they wouldn't be working for a paycheck at the DOE. They'd be making millions elsewhere.
 
Similarly, I never trust a stock-pick from some "expert with a great track record" unless he himself has earned a fortune picking stocks.

Mileage Vs Speed by bergyone
Jun 11, 2008 (12:49 pm)
I have a 2002 I-4 Camry. I normally get over 30 mpg on the Interstate, going the speed limit of 70. Is there a resource that will give the mpg vs speed for this car? Short, low speed trips reduce mileage significantly.

For mpg vs. mph, I don't know of a source for 2002 Camry #s (you'd expect mpgs to decrease as speed goes up, of course). I assume you don't have a trip computer in the car. If you're really curious ($170 curious), you can get a Scangauge that plugs into your OBD-II port, discussed here:Scan Gauge blog

My Sonoma only gave me 22.9 mpg this last tank. Ends up as $5.10 per round trip to work.
 
Okay, it's a boring afternoon at work so I crunched a few numbers and came up with an interesting result.
 
So far this week I've traveled 119 commuter miles. I've used zero ounces of gas. However, I have used about 20 ounces of water per each 34-mile round trip.
 
What does all this mean? Glad you asked.
 
20 fluid ounces equals 0.15625 gallons. Since I use around 20 ounces for every 34 miles that comes out to 217.6 miles per gallon...of water.
 
It looks like my commute ends up as $0.00 per round trip to work. Well, actually I do get a monthly water bill, so it's not entirely free - maybe a few cents - but I bet it beats any hybrid on the road.
 
On top of that I just found something to do to unbore myself for a few minutes.
 
BTW, I noticed that gas is going for $3.88/gal today as I pedaled past.

14 MPH wind is not a breeze in my book.
 
Actually 14 MPH is considered a moderate breeze and is a force 4 on the Beaufort scale.
 
Also remember that wind turbines are usually installed well above ground level which would have higher wind speeds.

I think you can, I believe it takes 5 MPH for you to start to feel wind.

Because it's the Windy City.
 
However, it got that moniker because of the longwindedness of politicians, not because of the breeze. Windy City
