No more GM diesels?!
GM goes 100% electric And Ford has made similar announcements. Is this the end of pickups? I haven't seen a glimmer of a electric p/u with 500 mile range and 3500 pound carry capacity have you?

Given that electric motors are well over 90% efficient, and that even coal generation (37%) is more efficient than ICE (30% in an ideal world, and 20% if it isn't) I think your statement that ice is more efficient is nonsense. Transmission line losses in an ideal world are 1 to 2%.agesilaus wrote:
And also note that electric vehicles just transfer the burning of fossil fuels from the vehicle (the efficient way) to a distant power plant (inefficient because of transmission losses and second law losses)
Beg to differ, make power at 37% efficieny, transmit it at 98% which gives you 36%. Then use it in a electric vehicle at 90% gives you about 32% so that is roughly the same considering Toyota claims 37% thermal efficiency. However most power is generated in Natural Gas Turbines these days which are more . So that makes it like 65% efficient which changes the whole calculation.
And your solar claim holds up only if you limit driving your lefty mobile to days when when solar works. No driving on cloudy days or at night.
