# This analysis of

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.html`
`Total 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:

Here's a great little paper on refinery electricity usage:

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

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
