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.

Battery technology has already made our lives more portable and convenient. From the disposable alkalines you used to use to power your Walkman to the modern rechargeable batteries in your cell phone and laptop, they allow us to take our work, entertainment and communication systems on the go. But batteries might have an even grander destiny: they could revolutionize the way we generate and use energy all throughout the home. Read on for a glimpse into our battery-powered future.

From Electric Cars to Your Living Room

Leading the charge into the brave new world of batteries is Elon Musk, CEO of Tesla Motors. Musk recently launched Tesla Energy, a suite of batteries designed to facilitate flexibility for consumers and ultimately pave the way to an energy grid that doesn't rely on fossil fuels.

"Our goal," Musk said at a press conference, "is to fundamentally change the way the world uses energy."

Tesla used its expertise in designing batteries for electric cars to make batteries bigger and more powerful. The company’s new lithium-ion batteries are optimized to enable “homes, business, and utilities to store sustainable and renewable energy to manage power demand, provide backup power and increase grid resilience,” the company promises.

Energy at Any Time of Day

Because Tesla’s new battery technology allows residential and business users to store electricity until it’s needed, it creates the opportunity to purchase electricity during off-peak time, easing the stress on our electrical grid. It also helps users get more out of sustainable but intermittent fuel sources like wind and solar.

If the technology catches on, consumers can take better advantage of utility time-of-day pricing. Some utilities in North America sell electricity at cheaper rates during nights and weekends, when there is less demand. A homeowner could therefore charge a battery at night and use it during the day, which saves money for them and reduces the generation cost for the utility company by smoothing out the demand.

Furthermore, as solar and wind technologies become cheaper and more viable, the ability to store their output means that they can further cut into the market share of fossil fuels like coal and natural gas, reducing human impact on climate change.

Keep the Lights On and the TV Running

Another advantage of the enhanced storage potential is that homeowners will still have power in the event of a blackout or other disruption to the power grid. And people who want to go off the grid entirely with solar energy can do it without worrying about running out of power during the night.

The batteries are expensive, starting at $3,000 for residential models. If the program takes off, the price should fall and ever-better technologies will be developed to improve storage, capacity, transmission and other specifications.

For now, the Tesla batteries look like a useful, if expensive, addition to the energy-conscious homeowner's arsenal. If prices do continue to fall, however, the batteries could transform into something truly revolutionary.

If you’re ever a contestant on Jeopardy and you’re asked what a GFCI is, you can respond by saying, “What is a ground fault circuit interrupter.” But knowing what GFCI stands for doesn’t mean you understand what it is. You’re not alone—the average homeowner is unaware of what a ground fault circuit interrupter does, but when your house’s ground fault is compromised, it can put the entire property, and your family, in danger.

A ground fault is an electrical path between a power source and a grounded surface. While all electrical devices and appliances are “grounded” to ensure they can be safely operated, devices can still lose their grounding and divert electrical currents to the nearest channel that provides a path to the ground: you. That’s why you need ground fault circuit interrupters in your home.

You’ve probably seen GFCI and never given them a second thought. They’re a common safety feature found on your electrical outlets that can be identified as two small buttons located in between the two sockets, the GFCI’s function is to constantly monitor the power current flowing through a circuit. At the first sign of a discrepancy between the current flowing into the outlet and the return current, it intervenes by shutting off the power to the outlet.
