Here are some websites about hybrids vehicles

• 40mpg.org
  From the website: “May 9, 2005: Americans using the 40mpg.org calculator have learned that they could cut their personal vehicle carbon dioxide (CO2) emissions by more than a quarter million total pounds per year by switching to 40mpg fuel efficiency. In the process, they would save over $30 million at the gas pump and need 13 million fewer gallons of Middle Eastern oil...”

  Barrett Silver’s website has a log showing the gas mileage he’s getting from his 2004 Toyota Prius. His graphic showing displayed, actual, and running average gas mileage is excellent.
