Evaluating Energy Systems in Cars<\/strong><\/p>\n

Energy storage has revolutionized how we produce and use energy. \u00a0One of the best examples is the Electric Car. \u00a0 A few years ago King and Donihue each needed a new car. \u00a0 This is what we learned from our purchasing research.<\/p>\n

As I was investigating car options I visited the local car dealerships and test drove a number of cars. \u00a0 Being an unrepentant techno geek I asked why the Prius gets better fuel efficiency in the city rather than the highway. \u00a0 \u00a0I also wanted to know why the diesel VW Golf had better fuel economy than the gasoline version. \u00a0 The car sales folks were clueless. \u00a0 Clearly not a product of a liberal arts education. \u00a0 I started to do some digging to get the answers to my questions.<\/p>\n

Cars move when we apply power to the wheels (Read about horsepower<\/a>). \u00a0Traditionally, the power came from an internal gasoline engine. \u00a0Today we have cars powered with gasoline, diesel, and electric engines. \u00a0 This is what I learned starting with a conventional gasoline engine:<\/p>\n
