Reducing your energy bill is a great way to lower operating costs and increase your bottom line. However, the large upfront investment required for many efficiency upgrades is often a barrier, despite the long-term financial benefits. So Duke Energy recommends some cost-saving steps: 1--Take a walk. A walk-through energy audit is free and it is a great way to uncover cost-saving opportunities. Visually inspect your home or business to look things that waste energy.  2--Use only what you need. This is the simplest and often the most effective energy-saving strategy. Turn off lights, motors, and electronic equipment when they are not being used.  3--Control temperature settings. Set building temperatures to minimize energy use while maintaining occupant comfort. Recommended energy-saving temperatures are 68°F in the winter and 75°F in the summer.
