"This is plug in hybrids are not a viable option for clean energy and curbing pollution if a Nation’s main source of energy is coal."

This is 100% wrong.

Our current power grid emits about 1.3 pounds of CO2 per kwh generated. This is our current grid, with current mixture of energy sources, and current technology.

One gallon of gasoline burned will produced 20 pounds of CO2. It doesn't matter who clean or unclean it is. It doesn't matter the mpg or size of vehicle. If you combust 1 gallon of gasoline you will emit 20 pounds of CO2.

EV gets about 3-5 miles per kwh so using current energy grid that is about 0.26 to 0.43 pounds per mile.
At 20 pounds of CO2 per gallon you would need to get 43mpg to 76 mpg to produce equals amounts of CO2 in internal combustion engine.
Even 100% coal powered electric vehicles are substantially cleaner than average internal combustion engine.

How can this be?
Internal combustion is insanely inefficient.
Tank to wheel efficiency for ICE is about 12% = 12% of fuel burned produces work the other 88% is wasted.
Battery to wheel efficiency for EV is in the 80%-94% range.
Gasoline can never overcome that

You keep talking about no pollution, and emission testing. You are aware that your emission testing doesn't even measure CO2 right. You can't combust gasoline or diesel (or natural gas, or propane) without producing CO2. It is impossible.
