Question 1 : You are a Volkswagen executive deciding which is the best way to improve the environment, after your plans for the sale of large numbers of diesel-powered cars were shelved. You have to decide between producing a 60% more efficient gasoline-powered VW Golf, or continue producing the e-Golf, an electric powered vehicle. Calculate and explain which option produces the least amount of Carbon Dioxide emissions, assuming:

-The current 2015 gasoline-powered Volkswagen Golf emits 62 g C/km

-Average emission rate for electricity in the USA was 1,232 lbs CO2/MWhr

-Development, manufacturing and recycling costs are identical

-The Volkswagen e-Golf has a combined fuel economy of 29 kWhrs/100 mi

-The Rebound Effect is perfectly balanced by Range Anxiety for electric car buyers, so buyers of the electric car would drive the same distance per year.

-Buyers of the more efficient gasoline-powered car will drive 10% more per year

-Average car miles per year is 12,000 before any changes.

Explanation / Answer

Volkswagen Golf gasoline-powered emits 62 g C/km but the average car produces = 170g C/km

=1,232 lbs converted into km = 558 /62 = 9

electricity in the USA = 1,232 lbs CO2/MWhr

Volkswagen e-Golf = 29 kWhrs/100 mi

=1,232 lbs/ 29

=42.48

so Volkswagen Golf gasoline-powered emits is better
