In a new study in The Proceedings of the National Academy of Sciences University of Minnesota researchers report in various scenarios that vehicles using alternative fuels are often more harmful to human health than are conventional gasoline-powered automobiles. From the abstract:
We find that powering vehicles with corn ethanol or with coal-based or “grid average” electricity increases monetized environmental health impacts by 80% or more relative to using conventional gasoline.

The AP reported:
"It's kind of hard to beat gasoline" for public and environmental health, said study co-author Julian Marshall, an engineering professor at the University of Minnesota. "A lot of the technologies that we think of as being clean ... are not better than gasoline."
Not surprsingly, the study does find that vehicles powered by electricity derived from wind and solar power have the least health effects. Keep in mind, however, that solar provided 0.23 percent and wind 4.13 percent of U.S. electricity in 2013.
Ping.
I’d love to short Tesla stock, but I’m smart enough never to bet against a regime affiliated company.
I love the Tesla because it is a very well thought out electric car.
However, all of us who have made it through at least undergrad Physics/Engineering curricula know this.
To an MSM bottom O’the SAT barrel slug, well, it’s news.
So, purchase a Tesla if you want to have fun with a very neat machine, but don’t fool yourself into thinking you’re saving the earth. (P.S., true also for Prius types. At least the Tesla folks get a cool carl)
It’s not about being green.
It’s about being smug about being green!
I like what the graph shows but horseshite science is horseshite science, whether it affirms or denies your beliefs
Seems to me this is really just another attack on coal generated electrical power.
Oops, that’s obviously “cool car”, not “cool carl”.
An Obamadork moment.
Until the regime changes.
Furthermore, what is this Mortalities BS? What a crock!
The Age of Smog replaced by The Age of Smug
Audacity so thick, ya can cut it with a feather.
Liz Warren doesn’t like Tesla?

I ride a motorcycle—100 MPG, and a full tank costs me $1.05! (With gas at $1.999)
Studies like this assume “health effects” start at the tailpipe. They don’t.
It takes 6-9 kWh of grid electricity to refine one gallon of gasoline.It takes diesel(7-10 kWh per gallon) to transport gasoline to gas station. Then it takes grid electricity to pump gas from station tanks into gasoline car.Then 75%-80% of energy in gasoline is wasted as heat. A Tesla is 90% efficient.If we simply stopped refining oil into gasoline we would have enough electricity to fuel an American fleet of electric cars.
Virtually all of our electricity is American sourced with a bit imported from Canada. Gasoline cars prop up global demand for oil which props up global price for oil which in turn bank rolls Czar Vladimir,Caliph Ibrahim,Ayatollah Khamenei, King Abdullah, and Presidente-por-Vida Maduro.
Apparently they didn't include electricity from hydro or nuclear.
Ping.
This is the AP here. The graph clearly shows the story is a hit on coal electricity generation and nothing else. They of course would be perfectly happy with heavily $ub$idized windmills and solar panels.
