1. An energy management system, comprising:
- a first energy source having a first well-to-wheels greenhouse gas emissions content;
a second energy source having a second well-to-wheels greenhouse gas emissions content;
a prime mover disposed in power communication with said first energy source;
a power distribution and conversion mechanism disposed in electrical communication with said prime mover and said, second energy source;
an electric drive mechanism drivingly engaged by said power distribution and conversion mechanism;
a controller communicating with said first energy source, said second energy source and said power distribution and conversion mechanism; and
wherein said controller is adapted to operate said electric drive mechanism using said first energy source when said first well-to-wheels greenhouse gas emissions content is less than said second well-to-wheels greenhouse gas emissions content and said controller is adapted to operate said electric drive mechanism using said second energy source when said second well-to-wheels greenhouse gas emissions content is less than said first well-to-wheels greenhouse gas emissions content.

Abstract
An energy management system includes a first energy source having a first well-to-wheels greenhouse gas emissions content, a second energy source having a second well-to-wheels greenhouse gas emissions content and a drive mechanism powered by the first energy source and the second energy source. The drive mechanism is powered by the first energy source when the first well-to-wheels greenhouse gas emissions content is less than the second well-to-wheels greenhouse gas emissions content and the drive mechanism is powered by the second energy source when the second well-to-wheels greenhouse gas emissions content is less than the first well-to-wheels greenhouse gas emissions content.

8. An energy management system for a hybrid electric vehicle, comprising:
-
a first energy source having a first well-to-wheels greenhouse gas emissions content; a second energy source having a second well-to-wheels greenhouse gas emissions content; prime mover disposed in electrical communication with said first energy source; a power distribution and conversion mechanism disposed in electrical communication with said prime mover and said second energy source; an electric drive mechanism drivingly engaged by said power distribution and conversion mechanism; a vehicle controller communicating with said first energy source, said second energy source and said power distribution and conversion mechanism; wherein said vehicle controller is adapted to receive said first well-to-wheels greenhouse gas emissions content from said first energy source and said second well-to-wheels greenhouse gas emissions content from said second energy source; and wherein said vehicle controller is adapted to operate said electric drive mechanism using said first energy source when said first well-to-wheels greenhouse gas emissions content is less than said second well-to-wheels greenhouse gas emissions content and said controller is adapted to operate said electric drive mechanism using said second energy source when said second well-to-wheels greenhouse gas emissions content is less than said first well-to-wheels greenhouse gas emissions content. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
