It seems apparent that the world is heading towards an energy crisis. The meter is heading towards "E" on petroleum and we need an alternative fuel vehicle. Cars can't run on good wishes alone and we need an alternative fuel source that is both economical as well as earth-friendly. One of the options for efficient energy seems to be the hybrid electric vehicle. Hybrid electric vehicles are a top contender to be the alternative fuel vehicle, replacing the gasoline powered vehicles of today. They are efficient, reliable and becoming most cost effective every day. No wonder they're quickly becoming popular. Besides the "green" factor, the designs of these types of vehicles are also pleasing to the eye - unlike the early clunky looking models.
