“Hi. I’m Craig Bryant with Bryant Electric Service, and I’ve been in business in Austin for almost 30 years now. I’ve been asked by many people a lot of different things about electrical work, and so I hope I can help with answering some of your questions as well.

OK. I’ve been asked many times about the difference between aluminum and copper wire, and the biggest difference is that copper is just a lot more stable metal than aluminum. And electricity, the biggest enemy to electricity is heat. The hotter it gets, the more important it is to have a stable metal. Aluminum is good but not as good in that in the long run over many years or decades because the instability of aluminum, when it heats up it contracts and expands. As it cools down, it contracts and heats, it expands.

So that happening over time over years and decades especially at your main service or wall plugs or something then that causes a loose connection and it starts arcing and the arc can create a fire over time. That just doesn’t occur in copper ever if it’s installed properly and it’s real tight at the beginning when it’s installed.

So the other problem with aluminum is oxidation. As they’re both exposed to air, copper oxidizes as you can see when it turns green, but it doesn’t affect the connection of the wire. Whereas aluminum, when it oxidize, it creates this crust that builds on it. And you’ve probably seen it before, but this crust can sometimes get as much as a quarter inch thick. And besides the fact that the metal is not as compatible to the heat and temperature problem. With that crust building up, it will also create a gap between the connections that can cause an arcing.

So copper is always better than aluminum and everything except price. And the main reason that it’s being used is because it’s so much cheaper.”

One of the best ways to save on your energy bills is to limit the amount of energy you use in the bathroom. Easily save money and energy in your bathroom by following these 9 simple steps.

Water heating is the second largest household energy expense, after heating and cooling. Cutting your shower time by two minutes can reduce your water use and lower your energy bills.

Lowering your water heater’s thermostat to 120 °F can help you to improve the performance of your water heater and cut your water heating costs. If you plan to be away from home for at least three days, turn off your water heater or turn the thermostat down to the lowest setting.

Lighting accounts for about 10 percent of your household electricity costs. Turning the lights off when you leave the bathroom is an important energy conservation measure.

Switching to energy-saving light bulbs is one of the easiest ways to start saving energy in your bathroom. When shopping for light bulbs, look for the Energy Star label to identify energy-saving products. For further energy savings, choose LED light bulbs, which typically use 75 percent less energy than incandescent light bulbs.

Leaving your bathroom extractor fan on too long can remove heat from your home. Save energy by turning off your fan when you leave the bathroom.

Ventilating your bathroom can go a long way toward creating an energy-efficient environment; research reveals that it costs less to cool or heat a dry environment than a damp one. Improve the ventilation in your bathroom by leaving a window open when you’re taking a bath or shower.

Sealing any air leaks with caulk, weatherstrips, or sealant can cut your energy costs and create a healthier indoor environment. For best results, focus on filling gaps around your windows and plumbing.

Older water heaters can use more energy than new ones, so replacing them can help you cut your energy bills. When shopping for a new water heater, consider the size, fuel type, and energy efficiency before making a purchase.

Leaving appliances plugged in wastes energy, even when they’re not being used. Be sure to unplug your appliances after using them, or switch them off at the wall.

Learning how to conserve energy in the bathroom doesn’t have to be a challenge. By following the above tips, you can maximize your energy savings and cut your energy bills.
