Steven,
A lot (but not all) of the "big picture" numbers you're looking for
can probably be found in the following report from the US Department
of Energy:
http://www.energy.gov/engine/doe/files/dynamic/1952003121241_chapter7.pdf
America?s Energy Infrastructure
A Comprehensive Delivery System
Some of the factoids I found in the report include:
About 204,000 miles of long-distance
transmission lines move power from
region to region.
There are roughly 5,000 power plants
in the United States, and they have a total
generating capacity of nearly 800,000 megawatts.
Over the next ten years, demand for
electric power is expected to increase by
about 25 percent, and more than 200,000
megawatts of new capacity will be required.
Altogether, 204,000 miles of transmission lines in North
America move power from the point of generation
to where electricity is needed. There
are 157,810 miles of transmission lines in
the United States. Transmission grid expansions
are expected to be slow over the next
ten years, with additions totaling only 7,000
miles.
The Bureau of Land Management
(BLM) estimates that 90 percent of the oil
and natural gas pipeline and electric transmission
rights-of-way in the western United
States cross federal lands.
The BLM administers 85,000 rights-ofway,
including 23,000 for oil and gas pipelines
and 12,000 for electric transmission
lines. It processes over 1,200 pipeline and
electric system right-of-way applications a
year,
Virtually all natural gas in
the United States is moved via
pipeline. The current domestic
natural gas transmission
capacity of approximately 23
trillion cubic feet (tcf) will be
insufficient to meet the
projected 50 percent increase
in U.S. consumption projected
for 2020.
The two million miles of oil pipelines
in the United States are the principal mode
for transporting oil and petroleum products
such as gasoline. They account for about 66
percent of domestic product movements
A modest-sized pipeline carries the equivalent of 750
tanker truckloads a day?the equivalent of a
truckload leaving every two minutes, 24
hours a day, 7 days a week.
The Trans-Alaska Pipeline System is
the single most important crude oil pipeline
in the United States
Since beginning operations in
1977, it has transported more than 13 billion
barrels of oil from Alaska?s North Slope
across 800 miles to the Port of Valdez.
Approximately 3.3 billion barrels of oil and petroleum products
and 229 million short tons of coal move
through the nation?s ports and waterways
every year.
477 foreign tankers and 64 U.S. flag tankers deliver oil and petroleum
products to the United States. They
deliver approximately 2.1 million barrels a
day, for a total of 770 million barrels a year.
In 1999, domestic railroads carried 68 percent
of the nation?s coal, and in 2000, they
transported an average of 14.4 million tons
of coal a week.
==========
Please have a look at the report, and let me know what sort of
additional information you need to make for a complete answer to your
question.
Thanks,
