Sorry JasonGar, you're not as smart as you might think.
Internal combustion engines are at their best approximately 15% efficient ( en.wikipedia.org/wiki/Internal_combustion_engine#Energy_efficiency )
While an electric motor is upwards of 85% efficient ( www.engineeringtoolbox.com/electrical-motor-efficiency-d_655.html )
If we take a hypothetical 100% coal-fired power grid mixture:
The most common power plant, the combined cycle turbines, get ~60% efficiency. ( en.wikipedia.org/wiki/Combined_cycle#Efficiency_of_CCGT_plants )
This is then transported at an average ~7% transmission loss over power lines to your home: ( en.wikipedia.org/wiki/Electric_power_transmission#Losses )
It then charges the lithium-derivative power cells in the car at above 99% ( batteryuniversity.com/learn/article/charging_lithium_ion_batteries )
Aaaand then that power is utilized in a 85%+ efficient electric drivetrain as mentioned above.
Sorry bro, you don't win.
Someone in the comments below mentioned the Prius and its Nickel Metal Hydride (NiMH) batteries being very polluting. He's right. it utilized a lot of processes and smelting operations that well, were really shit. Thankfully, most if not all commercially marketed EVs use lithium ion, lithium polymer, or lithium iron phosphate batteries, which is made from a soft, non-toxic metal that is otherwise often prescribed as a health supplement that is then hydraulically extruded and yadda yadda, completely bypassing the battery toxicity issues.
EVs are the future.
