Environment & Energy

Over their lifetimes and use less energy than their ICE powered equivilents.
The equivilent mpg that EV's are rated against is based on the amount of energy in one gallon of gasoline (33.7kWh).The amount electrical energy used by EV's is usually expressed as wH/mile or kWh/mile. One comparison would be a Tesla Model 3 that uses ~ 0.240kWh/mile. One ICE powered equivilent to it is considered to be the BMW Series 3 that gets 35mpg. The Tesla Model 3's mpg-e (miles oer gallon equivilent) is 33.7kWh ÷ 0.24kWh = ~130 mpg-e. Meaning the Tesla can travel about 4 times farther on the same amount of energy as it gas powered equivilent.

A look up of electric and gasoline prices in Texas shows 13.83 cents per kWh for electricity and $3.09/gallon for unleaded gas. To travel 35 mile in the Model 3 (at least if you charged at home) would be
- Amount of electricity to travel 35 miles is: 35 miles × 0.24kWh/mile = 8.4kWh. At 13.89 cents/kWh that would cost 8.4kWh × $0.1389/kWh = $1.17 vs the $3.09 it would cost for 5he gas powered equivilent.
Texas produces a relatively high amount of renewable electricity. As that percentage increase the EV will become even greener.
