Best Fuel to Replace Gasoline
 Interest in electric vehicles has been around for quite a while now. But with the way things have evolved, it appears that ethanol is becoming the fuel of choice in most people’s minds.
How do we know this? Public opinion surveys by the National Renewable Energy Laboratory conducted in December 2000, August 2004, and February 2007 posed this question: "Consider a future date when gasoline is no longer available. Which of the following do you think would be the best fuel for use in personal vehicles: electricity, ethanol, or hydrogen?" A comparison of the answers from the three different survey years shows a change in the public's view of future fuels. In both the 2000 and 2004 surveys, electricity was chosen more often than any other fuel type. However, in 2007, ethanol was chosen by more than one-third of the respondents, and a growing percentage chose electricity as the worst fuel to replace gasoline.
