Hold on there a minute, WattsUp. I would be the first to complain about smog and ICE vehicle exhaust, but what you see in that photo isn't smog, it's haze. As someone who grew up in the yellow smog of LA, I know smog when I see it. Haze is just a clear humidity interfering with visibility. Once you add pollutants to it, it turns a sickly, yellow-brown tint. Back in the 70's, one could literally smell the basin of smog as one landed at LAX.WattsUp said:Note the thick smog floating above the valley floor in the background, from the ICE masses living in their own filth
Well, the photo doesn't do it "justice". Perhaps SV smog can't compete with LA smog, but what you see in the photo really looked like smog in person, from up there on Mt. Hamilton. It was clearly brown and yucky looking... not just some friendly natural haze.unplugged said:Hold on there a minute, WattsUp.

Not sure why you're incorporating kWh into your gasoline cost calculation. Why not just multiply 37.7 by the average price for a gallon of gas?JimB_FFE said:1130 miles / 30 MPG = 37.7 gallons X 36.7 kWh = 1381 kWh which cost me $150.
I like your energy consumption context. It is a great way to show the complete savings by having an EV. It's not just dollars, it's energy you're saving. And because you're using less energy for transportation you thus have lower costs.JimB_FFE said:I thought that putting a kWh equivalent number on the car consumption would allow an apples to apples comparison of the impact of transportation on household energy use.
By switching to an EV, I cut household consumption by 1082 kWh per month, 35.6 kWh per day, or about 1.5 kWh per hour.
That's like leaving a 1500 watt heater on, full blast, outside, running continuously.
There's so much focus on cost savings. I thought the kWh numbers would provide some energy consumption context.
Well sort of: Since a hybrid doesn't have any external source of electricity for the electric motor this statement isn't quite true.hybridbear said:That's why hybrids get better MPG, they use the gas engine when it's most efficient and an electric motor when it is most efficient to reduce overall energy consumption.
Your statement above is not correct for hybrids other than the Prius. The Prius rarely uses the generator motor to pace a load on the ICE, instead relying much more on regen braking. The MPG gains from regen braking are much less in the Ford hybrids. The Fusion Hybrid consistently uses the generator to place a load on the ICE to get it operating in a more efficient BSFC region. This is a big part of why it is so efficient. ICEs operate most efficiently at a fairly high load. The FFH usually uses the generator to place about a 10 kW load on the ICE to make it more efficient.jmueller065 said:Well sort of: Since a hybrid doesn't have any external source of electricity for the electric motor this statement isn't quite true.hybridbear said:That's why hybrids get better MPG, they use the gas engine when it's most efficient and an electric motor when it is most efficient to reduce overall energy consumption.
Hybrids are more efficient because they attempt to make use of wasted energy. Specifically the energy wasted during braking and when sitting at a light.
With a hybrid the energy captured during braking is reused during acceleration to reduce the amount required of the gas engine. In addition there is some extra savings by being able to turn off the gas engine when the vehicle is not in motion.
Very interesting. I didn't realize that the Ford hybrid generator placed a load on the engine. Makes sense. In fact, I often wondered why Prius didn't charge the hybrid battery at all during freeway driving.hybridbear said:The Fusion Hybrid consistently uses the generator to place a load on the ICE to get it operating in a more efficient BSFC region.

The reason for the way the Prius behaves is that its ICE operates in its best BSFC zone at a much lower power demand, less than 10 kW. The FFH ICE seems to prefer being loaded to 15-30 kW to operate in its most efficient BSFC region. The Ford & Toyota designs are very similar but very different at the same time.unplugged said:Very interesting. I didn't realize that the Ford hybrid generator placed a load on the engine.
