That makes sense. I don't think the Hymotion battery accepts any recharge at all while driving, so the regen can't refill what was spent getting...
This is a fair point, but I think it only changes the numbers modestly. From what I've read, the total energy overhead for oil ("well to tank")...
The answer depends on what your goal is. My goal is to minimize the amount of gasoline used, for a given travel distance. This also minimizes...
1 KWH delivered by Virginia Power creates 1.2 lbs CO2 (per US DOE): http://www.eia.doe.gov/pub/oiaf/1605/cdrom/pdf/e-supdoc.pdf I get roughly 4...

Ever the nerd, I'll go ahead and respond to the "bike miles are free" argument. Only because I looked up the data some time back and I'd like to...
Well, whether or not walking or biking use more or less fossil fuel than driving a Prius depends on how the calories fueling that activity are...
We lost the 5 mph bumper standard in 1983. The current standard is 2.5 mph. I think this is a perennial issue with the US insurance industry....
Well, you have to start with the arithmetic. They came up with a savings of about 1 percent of total C02 emissions. That was from eliminating...
Yeah yeah yeah. The Prius is quieter than the other cars they tested. At 5 mph. I get it. Oddly, the article didn't mention that the...
