It’s been a cold winter here in the eastern US. But the rest of the world, not so much-
I drove the 4 miles to work today, using 0.8 kWh in the process. That’s 5 miles per kWh.
This was better than average (in cold weather, I think I’m closer to 3 miles per kWh).
I am curious about how CO2 emissions emissions for this car stack up to a normal hybrid. I know that here in New England, as of 2011 the marginal CO2 emissions for electricity was 0.91 lbs CO2 / kWh generated (down from 1.1 in 2005).
I’m not going to worry about distribution & charging losses just yet, though they should make some difference. Using 5 miles per kWh, and 0.91 lbs CO2 / kWh, yields 0.18 lbs CO2 per mile, which is pretty good.
Gasoline produces about 19 lbs CO2 per gallon burned. I believe, but need to verify, that this figure excludes the upstream emissions of refining, etc., so the actual marginal number would be higher. But let’s stick with 19 lbs/gallon for now. To get the same CO2 emissions as I got this morning, my car would have to get 19 / 0.18 = 105 mpg. That’s tough to get in a conventional car, hybrid or not, even under ideal conditions.
I think on average I get more like 3 miles / kWh. That works out to 0.30 lbs CO2 per mile. The equivalent gasoline-only vehicle would have to get 19 / 0.30 = 63 mpg. For reference, Prius drivers typically get 48 mpg, while the Prius V (which is closer in size to my car) gets about 42 mpg, real world.
Bottom line- my Fusion Energi, in pure electric mode, has CO2 emissions that non-plug-in vehicles can’t really match.
I’ll sharpen the pencil as time goes on (and double-check that I’m not, for example, confusing lbs C with CO2).
This is my plug-in Fusion. I got a good deal on a lease. I am learning a lot about life with a partially electric vehicle; more to follow!
Given that Tesla’s Model S and the discontinued Roadster have been driven a combined 113 million miles and that this was the first battery fire, the company’s rate of catching fire was still only one-tenth the frequency of conventional car fires, Wedbush Securities analyst Craig Irwin said.
