As shown in class, a coal fired power plant emits about 0.82 kg of CO2 per kWh (kilo Watt hour) of electricity generated. The cheapest Tesla Model 3 offered for sale on the Tesla webpage consumes 25 kWh per 100 miles. As stated in one of the previous questions, burning 1 gallon of gasoline emits 19.64 pounds of CO2. Compute the "equivalent mileage" in terms of CO2 emissions for a car with a combustion engine. So, what is the mpg of a car that emits the same amount of CO2 per mile if the Tesla gets its electricity from a coal fired power plant?

A typical car driven 14,000 miles a year emits to the atmosphere about 12 kg per year of NOx (nitrogen oxides), which causes smog in major population areas. Natural gas burned in the furnace emits about 4.6 g of NOx per therm, and the electric power plants emit about 7.2 g of NOx per kWh of electricity produced. Consider a household that has 2 cars and consumes 10,000 kWh of electricity and 1,400 therms of natural gas. Determine the amount...
