BRIDGEPORT - Gov. Dannel Malloy and local power companies urged residents to conserve energy as southwestern Connecticut endured the sixth day of a historic heat wave today.

They said the state is facing record demand, and the high use of air conditioners is putting a strain on the power grid.

United Illuminating says people can conserve energy by setting their AC to a slightly higher temperature, and turning off lights and appliances when they are not being used.
