The math is about right. He saved ~25 miles/per gallon into 660,000 miles, gives you number of gallons saved. Multiply that by about about $3 per gallon and the numbers are pretty close to his estimate.
My opinion is that Hybrids make sense (for some users), while full electrics do not.
Full electrics still require the energy from the grid and the grid is less efficient at energy storage than petrol in a tank. So ‘someone’ is picking up the cost of electric, and while it should be the driver, that may not always be the case if public charging stations are used.
Hybrids make use of the energy storage of the petrol and get energy from the conventional gas engine, so the right person is paying for the energy and he gets the increased efficiency of the electric motor. No public services required and funds required for a new infrastructure and social engineering.
Sorry but his MATH is way off, he saved about 13,700 gallons getting 52 MPG vs 25 MPG on 660k.
82,500/13,700 =more than $6 He’d have to have been paying $6 a gallon to save the kind of money he is claiming... and while the average price of gas today is $3 in 2000, it was $1.51... it has spiked briefly to 4 during that time but the average cost of gas over the last 20 years has not been $3.
I have nothing against Hybrids, or electrics, but this guys math is WAY WAY OFF... It’s broken down in my original post.
