Tucson's first Alternative Energy EXPO is being held this month at the Tucson Convention Center. The event on Friday and Saturday Sep. 14 and 15 will include more than 40 exhibitors in areas like alternative fuels, green technologies and solar power.

We speak to two of the local businesses that will be there: The Solar Store and "Green Fleets" which converts conventional gas-powered vehicles to use Compressed Natural Gas. (CNG) The expo is hosted by PAG, Pima Association of Governments.
