I'm sure some less-than-green fellow would install a remote starter on it, too. Or rig it up to run the reactor 24/7.

Also, I read about cars with nuclear reactors in them in a Tom Clancy book. Rather, they were warheads installed inside hollowed-out A/C compressors, strategically distributed across the US by some Japanese organization or another, and used for nefarious purposes.

So, maybe the electricity would not be available to run an EV, but it is used to refine the gasoline; and it should be added to the carbon footprint of gasoline.

Here's the best source on this question, that I have found:

Gasoline and Oil

Which is really too bad -- why can't we find authoritative sources on this?

Extracting oil takes a lot of electricity. Refining oil takes a lot of electricity and natural gas.

A lot of our military spending goes to defending our oil supply.

I do consider the Department of Energy's Energy Information Administration to be authorative.

Hi Matt,

I've been looking around that site, and it is a bit dense -- lots of info, but not very easy to find specific answers. Do you have a direct link to how much energy is embedded in gasoline?

Rinse, repeat.
Sounds like a show I watched about a large farm totally powered by its own cow dung.

...this is just an annecdotal comparison, but a TV show about mining shale-oil in Canada mentioned that it took:

1 barrel of recovered oil to produce 25 barrels of normal (drilling) liquid oil

1 barrel of recovered oil to produce just 5 barrels of usable liquid oil.

...takeaway is: it's 5X harder to extract oil from shale oil than to simply drill for it.

Neil,

This PDF seems to show that gasoline refining is 87.7% efficient and 4.3% of the energy used is purchased electricity.

http://www.transportation.anl.gov/mo...ries-03-08.pdf

So I'm not sure you can just say that 7.5 kWhr went into the gasoline that could have been used for charging an EV. I think you'd have to use the 4.3% that was purchased. If the balanced was burned fossil fuels, you'd still have to convert that to electricity, so apply a 1/3 multiplier to that (to convert it to electricity instead of burning for refining).

So, 100 - 87.7 = 12.3% used for refining.

12.3% X 4.3% = 0.529% was purchased electricity.

33.4 kWhr/gal X .529% = 176.7 Whr of purchased electricity "embedded" in each gallon.

100 - 4.3 = 95.7% of energy used for refining was from "petroleum" sources.

95.7% X 12.3% = 11.77% of the energy in each gallon was "embedded" burned fossil fuels.

33.4 kWhr/gal X 11.77% = 3.93 kWhr of "embedded" refining energy from fossil fuels. But we cannot use that as electricity without burning it in an engine, so divide by 3. (Even so, I'm not sure you could just burn it in an engine to make electricity without refining it first).

3.93/3 = 1.31 kWhr that we would have if we burned the fossil fuel to make electricity instead of refining the gasoline.

1,310 + 176.7 = 1,487 Whrs of electricity we could have had to charge the EV instead of it being used to make the gasoline, about 1/5th of Nissan's number.

OK, what's wrong with my math?

Something I never even realized is that drilling a well requires Drilling fluid/Drilling Mud. This stuff uses a lot of water and clay with added chemicals. It's very energy consuming to make and to transport.
