The electric vehicle market is turning into a financial nightmare for many of the automakers and suppliers that invested in the technology. Hybrids only comprise three percent of total new car sales, despite there being over 40 different models. And fuel cells are still more science lab experiment than mass-production reality.

But in a different part of the market, the green revolution looks a lot more promising. Commercial truck fleets in the United States are now keenly interested in converting their trucks to nun on natural gas or propane.

OEMs such as Freightliner and Thomas Built Bus have jumped into the market. International now offers the Transtar Class 8 semi (above) that runs on CNG. A cost calculator on the truck maker's website shows that a fleet can save well over $150,000 in fuel costs over the six-year life of a truck.
