Oil Industry
Electricity used
to produce
California’s Fuel requirements
by William Korthof
Here are some more numbers I put together.
Let's take the total daily gasoline usage in the
state:
2001 data from http://answers.google.com/answers/threadview/id/398561.htmlTotal Petroleum Consumption: 75,600,000 Gasoline Consumption: 40,500,000
If the electricity factor is only 0.33, the daily
electricity used upstream for gasoline amounts to:
13,365 MWH per day.
That's got to be too low.
There are 11,000 gas stations in California
plus 13 refineries that produce gasoline
plus 48,417 active oil wells in the state (as of
2005)
plus around 6,000 miles of petroleum pipelines in the state
(with corresponding pumps)
I'm going to assume that a gas station in California has an
average electrical demand of 15 kW... could be more,
but I don't think the average could be much lower than
that----
The average oil well pump draws roughly 10 kW
(probably increases every year), here's a great paper on oil fields:
http://www.onepetro.org/mslib/servlet/onepetropreview?id=API-68-192&soc=API&speAppNameCookie=ONEPETRO
Here's a great little paper on refinery electricity
usage:
http://www.eia.doe.gov/emeu/steo/pub/special/california/june01article/carefinery.html
which shows 913 MW of electrical demand for the refineries
from the grid **PLUS** 1033 MW of cogeneration demand
And I'll make the wild assumption that there is 10 kW of
pumping capacity per mile of petroleum pipeline
Add these up:
11,000 gas stations x 15 kW = 165 MW and 3,960 MWH per day
refineries use 913 MW + 1033 MW = 1946 MW and 46,704 MWH per
day
48,500 oil wells in California alone x 10 kW = 485 MW and
11640 MWH per day
6000 miles of pipeline x 10 kW = 30 MW and 720 MWH per day
Total: 2,626 MW x 24 hours = 63,000 MWH per day
That doesn't include out-of-state and out-of-the country
sources.
I believe the CA oil industry extracts between 50% and 75%
of the amount of oil used in the state, though much of the
oil extracted in the state is sold elsewhere and we import
oil from elsewhere because the CA refineries prefer lighter,
lower sulfur oil for refining to meet CA fuel
standards. So that makes it even more complicated
