Solid point. Batteries are heavy, slow charging, less energy dense, and expensi
Gas tanks outperform in all 4 categories for storing energy.

Re: EV efficiency - This shouldn't be much of a surprise at all but I thought the graphics were interesting

Nice.

I will say that it doesn't really consider a couple of things

AC is not powered by the alternator. That's not how AC works.

Yeah that's what I was getting at. Belt driven compressor has to be more efficient than electric. But I'll admit

Umm, weight is a HUGE factor.

Not as big a factor when you are regenerating 65 % braking energy

They are way more efficient throughout lifecycle - all up including the cost

Going to buy a electric truck and put a hydroplant in the bed I'll be killing it

huh... that's like saying that if Mr. Fusion" reactors were more efficient, we'd

Of course which is why we do what we do, also why subsidies are throwing money

Those numbers look way off.

Please research and correct then

It doesn't take research to see the problems

It also varies greatly on the kid of driving you're doing. Stop and go under 45mph, maybe close to 20%. Highway driving

please share the simple math that proves this

You're kidding right. . . Compare hybrids vs non hybrids at it is about 22%
Zoobieman

Ok. Tell us about regenerative losses. Hint: they average 44%.

If energy efficiency was driven by pure science, not politics, we'd have Thorium reactors producing our energy

Again with electricty (i.e. EV) the power source has already been generated

The issue at hand with EVs is not the efficiency of the drivetrain

No doubt but I'm and engineer and the energy efficiency is what struck me. It's like comparing a heat pump to a heat

However, batteries can charge overnight at your house, so unless you're on a road trip, the time is takes to charge is
