Yes Richard H. EVs do not
Yes Richard H. EVs do not produce tail pipe emissions. However EVs do not typically require "Massive amounts of Electricity" We have an all electric house and use about 13,000 KWH of electricity per year. 85% comes from solar panels in the back yard and the rest from the electric company. Driving a Nissan Leaf 7000 miles a year at 5+ miles per kwh we only increased our electric consumption by about 1200 KWH which is less than 10% of the total energy requirements of a modern house. Massive amounts of electricity ....not even close. As you were quick to point out CO2 is produced (sometimes) when electricity is generated. You also neglected to tell us that CO2 is also generated when gasoline is produced which almost triples the CO2 signature of the typical gas car. The generally accepted number is 7 KWH of electricity is required to produce 1 ( ONE) gallon of gasoline. Therefor most gas car required MORE electricity per mile of travel than an EV.
So yes we all should be supporting Tesla for many reasons.
