Laclede Gas will be exhibiting at the second annual Eco Expo at the St. Louis Science Center on April 10-11.

Laclede Gas, the Original Green Energy, is encouraging customers in its service area to go green by enrolling in its e-bill service by April 30, 2010 to automatically be entered into a drawing for a chance to win a cash prize and a donation to the “green” charity of their choice.
