Is it true or not, that PG&E's biggest customers are the California Refineries. I have heard that, but I can't find any documentation.
This is a relevant post by Glenn Doty of Windfuels, in response to our own dhrivnak. I think it's worth repeating.
http://seekingalpha.com/article/4567...omment-4051451No, the petroleum refining is not the second largest water consumer in California. That's a complete flat-out lie.
The second highest water use in any state - including Texas (the state with the most refineries) - is the electric power industry. The first highest water use in every state is always agriculture. Usually the 3rd-10th highest users don't equal the total volume of the electric power sector.
No, it does not take any electricity off the grid to refine gasoline: That's a complete flat-out lie.
The refining process produces plenty of "petroleum coke" as a waste product that is burned in cogeneration power plants, and the heat and some of the electricity is used in the refinery, but the majority of that electricity is produced and sold to the grid. The exact ratio is ~1/267th of the electricity produced by petroleum refining is used in petroleum refineries - most of this power is used for things like lighting, electronic sensors, and office climate control..
The requirement for ICP oil shale recovery is HEAT, not electricity. Ergo, they typically use burners, not electric heaters. ICP oil shale recovery is experimental, and accounts for ~1/1000000th to 1/100000th the total oil on the market in any given year. To highlight THAT as proof that electric cars are somehow more efficient than ICE vehicles shows exactly how desperate the EV industry is to find a positive comparison (The numbers actually do work out slightly in the ICP oil shale's favor when compared to EV's, btw, but it's certainly a harder case to argue than the 99.999+% of the oil on the market that is not ICP oil shale derived).
How does Mr. Doty define "water use" In my state the electric utilities pump water to an upstream reservoir at night to be re-released during the day to make hydro power. This cycle is repeated on a daily basis. Is this considered "water use". Perhaps Robert.Boston can chime in and shed some light on where the water use is in regards to electricity production. I am having a hard time believing the electric utilities use as much water as Mr. Doty implies.
My local nuclear plant takes water from the sea to cool the superheated steam after passing through the turbines. The slightly warmer water is released straight back into the sea. The fish apparently love it.
Is this counted as water use?
Mr. Doty is looking for investors in a company that wants to convert electricity into liquid fuels to burn in inefficient ICE vehicles. It would seem to me that he has a much greater vested interest in making electric vehicles look bad then even the infamous Mr. Peterson.
Why should we even consider his wild assertions as facts without requiring unbiased references to back them up?
I do find it rather amusing that a staunch dis-creditor on Mr. Peterson's anti-EV BS chooses this Mr. Doty's writings to support his opinion.
Just a few excerpt from Mr. Doty's Web site follow.
Pure electric vehicles will never be the first choice for most consumers as a primary vehicle due to their range restrictions. With pure EV, traffic jams and unexpected errands will result in more cars running out of power. A 40-mile range is not acceptable for most drivers. (Remember, you simply canít stop in somewhere for a quick recharge.)And of course the best one must be this:The cost savings per mile are much less than the EV advocates claim, as they still often assume an electricity cost of $0.04/kWhr when the current average residential rate is $0.12/kWh (equivalent to gasoline at $4.36/gal). A reasonable estimate is that charging costs for the Volt would be similar to fuel costs for the Prius if gasoline were $2.70/gal. If you drive the Volt 8500 miles per year (and you wonít be able to drive it much more than that without being left stranded), and gasoline is $4.70/gal, your annual savings is $400
John Peterson has some of the best expertise and insights into the battery and EV markets. We highly recommend his articles, where are available here:
Here is my response to Mr. Doty.
You are correct about agriculture, I was referring to manufacturing in the heavy use of water. According to the EPA Water & Energy Efficiency by Sectors (Oil Refineries | Region 9 : Sustainable Water Infrastructure | US EPA) oil refining uses 800 million gallons of water a day, a very large user of water. Additionally "The petroleum refining industry is one of the most energy-intensive manufacturing industries in the U.S. The industry used 3.1 quadrillion BTUs in 2002.". 3.1 quadrillion BTUs is equivalent to the power generated by 317 large coal fired plants.
Another way to look at it is 3.1 quadrillion BTU / 3413 BTU/KWh is 2.73 KWh to the 12th power. Or enough to power 200,000,000 EV's an average of 13,000 miles a year.
I am not against oil or refining or drilling. But I am for what makes sense. When I can spend $28 in electricity to save $200/month in gasoline I will do so. The reason the cost/mile is so much less for electricity versus gasoline is the electric drive train is so much more efficient.
