THE BRONX - Staying cool during the summer can be costly, but there are some ways to save money without breaking a sweat.

Con Edison says that the easiest way to keep energy bills from skyrocketing is to turn off air conditioners, lights and other appliances when leaving home.

The power company also advises customers to set thermostats at no lower than 78 degrees because each degree cooler can increase costs by 6 percent.

Other energy-saving tips include keeping shades, blinds and curtains closed, and using a fan instead of the AC whenever possible.
