I'm an energy guru, it's sad to see how little people know.

You are correct...

That's only fair if you compare the energy it takes to make the batteries Lionessa Feb 2012 #1
That energy is already calculated in the energy it takes to build the vehicles, building an electric grahamhgreen Feb 2012 #2
Really? Got a link for that? I doubt you do. TheWraith Feb 2012 #6
No, the fact that it will take about as much energy to make a gas guzzler as an EV is common sense grahamhgreen Feb 2012 #22
No, it's not. It's a fairly large and unsupported assumption. TheWraith Feb 2012 #52
I'm pretty sure the batteries are not made on site but by battery manufacturers and then shipped for Lionessa Feb 2012 #7
That's true for a great many components of automobiles, the majority in fact.. Fumesucker Feb 2012 #11
Correct. Prius batteries travel a great distance before placement into the cars themselves. cherokeeprogressive Feb 2012 #18
About the same thing that happens with the oil. But over and over again, every time you fill your grahamhgreen Feb 2012 #23
"About"? Nuclear Unicorn Feb 2012 #56
The energy to make the batteries is a 1 time expense, energy to make a gallon of gas is per gallon ShadowLiberal Feb 2012 #9
You have a point, but batteries don't last forever, even if there corrosive chemicals do. Lionessa Feb 2012 #13
Batteries can be recycled. grahamhgreen Feb 2012 #31
Those "corrosive chemicals" do not last forever. PavePusher Feb 2012 #53
Batteries have to be charged as gas tanks have to be filled. NCTraveler Feb 2012 #28
The question isn't that focused. It's an energy-side question. joshcryer Feb 2012 #15
What about the energy it takes to provide the fuel hughee99 Feb 2012 #50
For the purposes of this discussion it is not useful to measure energy in kwh lumberjack_jeff Feb 2012 #3
Far less. Every time you drive a Gas car 30 miles, you use a gallon of gas PLUS whatever grahamhgreen Feb 2012 #5
You're looking at this backwards. lumberjack_jeff Feb 2012 #8
Eh, while true, it's not particularly useful. joshcryer Feb 2012 #19
The electricity comes from some source of fuel as well. antigone382 Feb 2012 #17
The point is that it requires 7.5 kwh of electricity to make a gallon of gas; so grahamhgreen Feb 2012 #32
Erm, if you're consuming less energy, and that energy is still fossil fuel based... joshcryer Feb 2012 #16
No. If I buy electricity to generate kinetic energy... lumberjack_jeff Feb 2012 #20
Nah, even if you take the nuclear plants in Lousiana and California... joshcryer Feb 2012 #21
You'd lose the argument, and by quite a bit IDemo Feb 2012 #36
It all depends on where you live. lumberjack_jeff Feb 2012 #49
Won't THIS piss off the hybrid-bashers on Craig's List? WhoIsNumberNone Feb 2012 #4
Hybrids cause more greenhouse gas emissions in many areas tabasco Feb 2012 #10
You're missing the point of the post - the gas powered car uses the electricity PLUS the gas. grahamhgreen Feb 2012 #26
No, you're missing the point. tabasco Feb 2012 #35
This tired old myth pops up on each and every EV thread online IDemo Feb 2012 #37
The "tired old myth" comes from Argonne National Laboratory tabasco Feb 2012 #44
Look at it this way, refining one gallon of gas requires 7.5Kwh of electricity. So, grahamhgreen Feb 2012 #40
I want an electric car but can't afford one Rosa Luxemburg Feb 2012 #12
Mitsubishi Imiev or the Prius-C (under 20K)??? Me, I ride a bike. grahamhgreen Feb 2012 #25
I can have only one car. So my car can't be electric. Honeycombe8 Feb 2012 #38
The problem with these type of calculations is they ignore the power plant. former9thward Feb 2012 #14
No, the gallon of gas uses NOT ONLY the electricity, BUT ALSO the oil!!! grahamhgreen Feb 2012 #24
Really? Got a link for that? LOL just kidding. Zalatix Feb 2012 #27
Thank you! I don't understand why they want to use the electricity AND the gas to go the same distan grahamhgreen Feb 2012 #29
K/R and DAMN, there's a LOT of misinformation in this thread... NYC_SKP Feb 2012 #30

Damn, only 22 miles per gallon average? Art_from_Ark Feb 2012 #34
The calculation is wrong -- 21000 BTU can generate about 2.4 kWhr of electricity FarCenter Feb 2012 #39
It takes 7.5 kWh of electricity to just to REFINE one gallon of gas; the car still has not moved. grahamhgreen Feb 2012 #41
No, it takes 21000 BTU of chemical and heat energy FarCenter Feb 2012 #42
I know that US refineries used 48,891,000,000 kWh of electricity in 2005. grahamhgreen Feb 2012 #46
It works out to 0.35 kWHr/gallon of gas. FarCenter Feb 2012 #48
There is a deeper discussion of how they arrived at the 7.5 kWh figure grahamhgreen Feb 2012 #51
shocking factoid...we can MAKE electricity...we can't make oil spanone Feb 2012 #43
K&R for an awesome discussion. The debate here is fascinating and coalition_unwilling Feb 2012 #45
Interesting libtodeath Feb 2012 #47
What's not factored into all of this HarveyDarkey Feb 2012 #57
Yes, but what if I want to go more than 100 miles HarveyDarkey Feb 2012 #54
Well, if you can afford it, buy a Tesla... grahamhgreen Feb 2012 #55
