With more and more hybrid and alternative fuel cars coming out each year, it has never been easier for consumers to go green with their car purchase. And, while hybrid vehicles by themselves don?t necessarily make you green, they have certainly become a symbol for being green with consumers.  For the second year in a row, Cars.com has taken a look at the cities across the country and ranked them by the number of hybrid searches as a percentage of overall car searches to come up with its Green Cities list, to be released on Thursday, April 30th.
