Kauai’s electrical grid surges affect the life span of our computers, appliances, and other electronic equipment. Power surges can also completely roast the internal electronic parts during a storm or utility fault.

A whole house surge protector installed by a licensed electrician will greatly decrease the risk of power surge destruction.

Guarding against surges requires a two-pronged approach: a whole-house suppressor to tame the big, dangerous power spikes and an individual circuit (or “plug-in”) surge suppressor for vulnerable appliances and electronic devices. Both types essentially act like pressure-relief valves. Normally they just sit there, allowing electric current to flow through them. But with higher-than-normal voltage, the devices instantly divert excess voltage to the ground wire. (The best ones react in less than a nanosecond.) As soon as voltage levels return to normal, the flow of electricity is restored, unless the surge was big enough to melt the fuse built into some units.

Typically, whole-house suppressors are hard-wired to the service panel, a process that takes a licensed electrician about two hours. Whole-house systems should be rated to stop a 40,000-amp surge, at minimum. Features to look for include thermal fuses, and lights or alarms that indicate when a device has taken a hit. Protection for an average house with 200-amp service will run about $500 — including a couple of hours of an electrician’s labor. Separate but smaller whole-house units are recommended for the phone and cable lines. These protect fax and answering machines, televisions, and modems.

By themselves, whole-house suppressors can’t stop surges completely; up to 15 percent of excess voltage may leak by. That’s where “plug-in” surge protectors come in. These buffers between individual appliances and wall outlets come in a bewildering array of options and prices. They range from $70 units not much bigger than a computer mouse to $350 units the size of a pizza box that guard all the components in a home theater. But most plug-in models fall into three basic categories: the familiar multi-outlet power strip; the multitasking surge station that can handle phone and cable jacks as well as power cords; and the UPS (uninterruptible power supply), which completely cleanses electric power of random fluctuations and provides a short-term battery backup in case the power dips or goes out entirely. Expect to pay between $20 and $70 for a quality power strip or surge station, and from $100 to $250 for a UPS.

You might think that there's not a whole lot that you can personally do to save money on your energy bill. After all, you need to shower, cook, use the lights at night and wash and dry your clothes -- all which take up electrical energy. You might be surprised to learn that there are small things that you can do to help save energy at home and in the process save money on your electric bill. 

1. Pack more efficiently

You pack more than just clothes for your next vacation. You also pack items into your freezer and refrigerator. Much like improper packing for your vacation will leave you with less room, not packing your refrigerator and freezer the right way can wind up using more energy. 

In general, a full refrigerator and freezer are more energy efficient. The more empty space there is in these appliances, the more space warm air has to replace each time you open the door. 

If you don't want to keep your freezer and refrigerator full of food, containers with water can be a great substitute. You can also try keeping the most used items by the door. 

2. Watch out for vampire power

Is your home a haven for vampire power? Vampire power, also called standby power, among other names, refers to the power that appliances used when they are plugged in but in standby mode or turned off. Some examples of common culprits of vampire power include televisions, computers and chargers for cell phones and other electronics. 

Put bigger electronics, such as computers and televisions, on power strips and get into the habit of flipping them off when you're finished with them. Unplug smaller electronics and your chargers when you aren't using them. Plugging up unused outlets helps stop the leakage of outside air into your home. 

3. Schedule a home audit

Nearly all homeowners want to save energy but few think that their home is a bastion of energy efficiency. An energy audit by a professional energy auditor can pinpoint the problem areas in your home and provide affordable ways to address them. Paying for the weatherization of your home can be expensive upfront. The long term energy savings as well as any tax breaks offered by the government can help you pay for it.
