If you can tear your eyes away from the plethora of displays and meters reporting back your instantaneous fuel economy and crank up the JBL Green Edge stereo to overcome the obnoxious noise made by the gasoline engine when it inevitably pops on — it sounds more like a large vacuum
cleaner than an internal combustion engine — then the Prius is not a bad ride.
Electric motors are just much better at that
transformation than internal combustion engines - which is why the somewhat wonky EPA conversion for MPGe (the electric equivalent of miles per gallon) shows a Volt getting like 119 miles per electric «gallon» worth of energy, and that conversion is actually pretty conservative.
After all, there are more people and
animals than internal combustion engines in the city, many of whom are full - time residents who do not even own an internal combustion engine, and who might smugly believe they are beyond the reach of carbon taxation.
Electric cars will mostly be replacing gas - powered vehicles, reducing air pollution and CO2 emissions (even if they are charged on the dirty U.S. power grid, they are still
cleaner than internal combustion engines, though of course the goal should also be to clean up the grid - but that's a discussion for another article).
In addition, because electric motors can be 2 — 3 times more efficient
than internal combustion engines, PV can result in 200 — 300 times more useable energy for vehicle transport than bioenergy per hectare (although fully realizing this potential will require battery production to become more energy efficient).
Because electric motors can be two to three times more efficient
than internal combustion engines, solar PV can result in 200 to 300 times as much usable energy per hectare for vehicle transport compared to bioenergy.
Propels the vehicle more quietly, smoothly, and efficiently
than an internal combustion engine and requires less maintenance
