From the perspective of CO2 emission,   Burning coal to generate electricity to power EV is worse then burning gasoline in internal combustion engined cars by about 10-20%

Please provide your calculation/estimation.

 More clever to say the Japanese got us into WWII by striking our naval base on Oahu.

It is equally fair to say once the oil embargo is in place a war with Japan is absolutely certain, the only unknown is how it will start.

It is certain because without war, the oil embargo can only end in total diplomatic humiliation and credibility collapse of either the U.S. or Japan.     Either Japan capitulate and pull out of China, or the US capitulate and does nothing while Japan seizes what is now Indonesia and Malaysia.

... and add to that the fact that the Japanese Navy, by its own estimates, had only enough oil reserves for about two years of normal operations, or eighteen months of combat ops. That put a hard deadline on their decision to go to war, as well as influencing which direction Japanese aggression would take.

Before WWII the US was a major exporter of oil. Cleverly, FDR got us into WWII by not giving the Japanese any of our oil.

Yes, ma'am, a harbor at the mouth of the Pearl River, with a nice restaurant with a balcony overlooking the Naval Station at Pearl Harbor, that was a lovely place for Yoshikawa Takeo, third assistant minster in the Japanese Consul on Oahu, to watch the comings and goings of the US Fleet under Husband E. Kimmel, officially CINCUS. Meanwhile, Nagumo Kido Butai was steaming east from Tankan Bay in the Japanese owned Kurile Island.

Thanks for your help, most informative.

They could have spooned it out by suspending most industrial production and limiting heating in private homes except at night, but they wouldn't have gained enough to realistically extend war activities to four years. This is why Yamamoto Isoruku said "I will run wild for a year and a half to two years. After that I promise nothing."

We had to prioritize as well.

1. National Reserve ( military fuel supply, including reserves)
2. US industry, especially arms and armament.
3. Great Britain.
4. US private consumers. (People gotta get to work.)
5. Others.

From the perspective of CO2 emission,   Burning coal to generate electricity to power EV is worse then burning gasoline in internal combustion engined cars by about 10-20%

Please provide your calculation/estimation.

coal emits roughly 220 lbs of CO2 per MMBTU,   motor grade gasoline emits about 150 lbs per MMBTU.  typical modern coal plants are about 40% thermal efficiency at bus bar, which means roughly 550 lbs of CO2 per MMBTU equivalent of energy delivered to the grid.    Typical road legal car drive train are about 30% thermal efficient, which means about 450 lbs of CO2 per MMBTU equivalent of kenetic energy delivered to the wheel. 

This is without considering transmission, distribution and battery charging loss, which amounts to more than 15%

The advantage reverses if the electricity used to power EV is generated by natural gas, which emits half as much CO2 per unit of thermal energy as coal, and gas burning combined gas and steam cycle turbine are thermally much more efficient than coal burning boiler abs steam turbine.  But china does not have abundant natural gas and natural gas does not account for significant portion of chinese generation portfolio as it does in the U.S.,    and abundant Russian natural gas cut off from Europe can not avail china because pipeline infrastructure does not exist.

[Anomalocaris]

so in china increase in electric demand that is not matched by a nearly equivalent increase in renewable, hydro or nuclear ge station is likely a net loss for climate change fight regardless of what the added electric load replaces,  unless it is other less efficient burning of coal such as open hearth home heating and cooking, which is not uncommon in parts of china.
