I really don't know what point you are trying to make. The chart from "ecogeek.org" is totally misleading, and probably intentionally so.
You say it's misleading but don't say how. But that's okay, I'll do the research.
From
http://www.eia.doe.gov/oiaf/servicerpt/anwr/pdf/sroiaf(2008)03.pdf, page 1:
In 1998, the USGS estimated that between 5.7 and 16.0 billion barrels of technically recoverable oil are in the coastal plain area of ANWR (also referred to as the 1002 Area), with a mean estimate of 10.4 billion barrels, of which 7.7 billion barrels falls within the Federal portion of the ANWR 1002 Area.
The key number there is actually the 7.7 billion. From the DOE site I linked earlier, there are about 18 billion barrels estimated to be in the "unavailable for leasing" areas that the GOP would like to open up for exploration. That's about 2.3 times what's estimated to be in ANWR.
Now from the executive summary of the above PDF:
Additional oil production resulting from the opening of ANWR would be only a small portion of total world oil production, and would likely be offset in part by somewhat lower production outside the United States. The opening of ANWR is projected to have its largest oil price reduction impacts as follows: a reduction in low-sulfur, light crude oil prices of $0.41 per barrel (2006 dollars) in 2026 for the low oil resource case, $0.75 per barrel in 2025 for the mean oil resource case, and $1.44 per barrel in 2027 for the high oil resource case, relative to the reference case.
I'll be generous and go with the high oil case. 2.3 times $1.44 = $3.31. That's how much the price of a barrel of crude would come down if you were to "drill here, drill now" - and that's not until 2027. For comparison, the price of crude rose about $16 today to about $120. So in 2027, assuming oil prices stay the same, you would have a savings of about 3% on crude. At its peak.
I would say lets work on alternative energy sources and ways to power the economy that are renewable - but hey, I posted a misleading chart, so what do I know?
(on preview, I see mmx1 did a bit of research as well.)
