Although the world has not run out of oil and North America has not run out of natural gas, and there are still lots of potential kilowatts to create, we have run short of any way to grow the supply of each of these energy sources. There is little growth in worldwide oil supply from new projects coming on stream.

The North American Natural Gas Cliff
Unlike oil, natural gas cannot easily be shipped by sea. It must be
liquefied prior to shipment, and then shipped in specially designed
refrigerated ships destined for specially equipped ports, and then
re-gasified for distribution -- at an estimated 15 to 30 percent energy
loss.
Moreover, natural gas cannot be easily stored like oil or coal. Campbell says that gas production is better described as a
"plateau" followed by a "cliff" due to the high mobility
and recovery of gas. Under declining pressure, oil declines slowly as it
moves through the porespace of the rocks, but the decline of gas is a cliff
-- not a slope. The gas market gives no warning of the cliff because it is
no
more expensive to produce the last cubic foot than the first. When Canada signed NAFTA, it ceded total control of its oil and gas
reserves. Canada currently makes up about 13% of the USA gas supply. North
American production is at or near (< 10 years) its "cliff" now.

Campbell says it is not practical to make up the North American shortfall
in gas by shipping it in from the Middle East (shortage of LNG facilities,
tankers, and energy loss). However, the construction of a new gas line to
Alaska and the Canadian arctic where there probably are large untapped
deposits could temporarily mitigate the North American gas cliff.
On October 17, 2000 (Reuters), a top BP Amoco official admitted that
there was a "dire need" for gas from both Alaska and northern
Canada. Forecasts show gas demand could outstrip supplies from traditional
sources by as much as 4 billion cubic feet a day within a decade! |
