When hiring an electrical professional, some things to look for are the extent of his or her training, licensing, insurance, expertise, and level of experience. This can help you choose a professional that can handle the type of job you need completed.

You know your home's HVAC system uses a lot of energy every year. Care to guess what percentage of your total electrical bill is consumed keeping your house temperate? If you're average, that would be over 31 percent or so.

How powerful should ventilation fans be? In kitchens and baths, fans should have sufficient power to exhaust a minimum of 1 cfm (cubic feet per minute) of air for every square foot of floor space.

If you are in the market for new computers for your office, you should consider Macs. They traditionally use less energy to operate than PCs. They are more expensive to purchase initially, but may save you money in the long run.

If you have a brief power failure in your home, check with your neighbors and the electrical company. If the problem seems isolated to your home, call an electrician to make sure the outage isn't a symptom of a bigger problem.
