How far could an EV go on the energy used to refine a gallon of gas?
The oil sands are even worse... far worse:

"The average "energy returned on investment," or EROI, for conventional oil is roughly 25:1. In other words, 25 units of oil-based energy are obtained for every one unit of other energy that is invested to extract it.
But tar sands oil is in a category all its own.
Tar sands retrieved by surface mining has an EROI of only about 5:1, according to research released Tuesday. Tar sands retrieved from deeper beneath the earth, through steam injection, fares even worse, with a maximum average ratio of just 2.9 to 1. That means one unit of natural gas is needed to create less than three units of oil-based energy."
So the claim is that 10 gallons of oil or gasoline, with a cash value of about $30, is used to generate 85 kWh of electricity, which is then sold by the utility for about $10. I wonder how utilities make a profit at that rate? Are they subsidized?
*cough*Create*cough* (or manufacture, etc...)Done
"Create" is a weirdly loaded term, so I've used "produce".*cough*Create*cough* (or manufacture, etc...)
If you use refine instead of create, it's terribly inaccurate and may give the anti-EV more ammo. At least, it did when Nissan messed it up...
I'd like to find out what the energy production looks like from this cogen process at the Kern operation in Bakersfield. They account for 10% of all natural gas consumption in the entire state of California, I highly doubt that equates to efficient(normal) electricity production.In the California oil fields, they separate out the water and natural gas, then use the natural gas to heat the water to steam, run the steam through an electric generator to produce electricity on the grid, then inject the steam into the wells to soften the oil. They call is cogen. The emissions are on par with a natural gas power plant. And waste products that are disposed of without any use elsewhere does some good. I believe the city of Bakersfield gets almost all its electricity from cogen plants out in the middle of the oil fields.
