Programmable thermostats can reduce energy consumption when you need it the least. Some of the latest models can be programmed around your schedule during the week and even on the weekends.
If you set your thermostat to a few degrees higher during the summer and a few degrees cooler in the winter while you are away from home or asleep, you could save nearly 4% on your total bill. Plus reducing this consumption helps reduce green house gas emissions.
A/C units shaded by trees or other means work more efficiently and use up to 10% less electricity. Also, when buying a new AC unit, look for a SEER (Seasonal Energy Efficiency Rating) of 13 or higher on central systems and the ENERGY STAR label on room units.
