What You'll Learn
Switch to energy-efficient lighting
Switching to energy-efficient lighting is one of the easiest and most effective ways to conserve electricity and reduce your energy bills. Lighting accounts for around 15% of an average home's electricity use, and by using LED lighting, the average household can save about $225 in energy costs per year.
LED (light-emitting diode) lights are semiconductors that convert electricity into light. They are the most energy-efficient type of lighting available, using up to 90% less energy than traditional incandescent bulbs, which only convert about 5% of the electricity they use into visible light. LEDs also last up to 25 times longer than incandescent bulbs, making them a more cost-effective option in the long run.
When choosing energy-efficient lighting, you can select from a variety of brightness levels, light colours, and dimmable options. You can also find LED replacements for almost any type of traditional incandescent bulb, including reflector bulbs, track lights, task lighting, under-cabinet lighting, and outdoor area lights.
In addition to choosing energy-efficient bulbs, you can also use controls such as timers and dimmers to save electricity. Timers automatically turn lights off when not in use, and dimmers can be used to lower light levels and reduce energy consumption.
By combining energy-efficient lighting with these simple control measures, you can significantly reduce your electricity usage and lower your energy bills, all while maintaining the same level of illumination in your home.

Reduce hot water usage
Water heating is the second largest energy expense in your home, accounting for about 18% of your utility bill. Here are some ways to reduce hot water usage:
Fix leaks
Leaks waste both water and the energy used to heat it. Check your pipes, faucets, and showerheads for any leaks and get them repaired. A leak of one drip per second wastes 1,661 gallons of water and can cost up to $35 per year.
Install low-flow fixtures
Low-flow showerheads and faucets can help reduce hot water usage. Aerating showerheads mix air with water, forming a misty spray, while laminar-flow showerheads form individual streams of water. Low-flow faucets typically have a maximum flow rate of 2.2 gpm for kitchen faucets and 1.5 to 0.5 gpm for bathroom faucets. For maximum water efficiency, look for aerators with flow rates of no more than 1.0 gpm.
Insulate water pipes and tanks
Insulating hot water pipes and tanks can help reduce heat loss, preventing the unit from turning on as frequently. This includes insulating the first 6 feet of both the hot and cold water pipes connected to the unit. Be sure to follow the manufacturer's recommendations, including not covering the heater's thermostat, burner, or the top and bottom of the unit.
Lower water temperature
Manufacturers often set water heater thermostats at 140°F, but most households are comfortable with 120°F. Lowering the temperature can cut costs, reduce scalding, and slow mineral buildup and corrosion in your heater and pipes.
Use energy-efficient appliances
When using appliances like dishwashers and washing machines, choose energy-efficient models that use less water and energy. Look for the ENERGY STAR label when purchasing new appliances. Also, consider using shorter cycles and cold or warm water for laundry loads to reduce hot water usage.

Unplug devices when not in use
Unplugging devices when they are not in use is a simple yet effective way to conserve electricity. Even when devices are turned off, they can still draw power from outlets, a phenomenon known as "phantom load". By unplugging devices, you can prevent this unnecessary power draw and reduce your electricity consumption.
One way to make this practice more convenient is to use power strips, which allow you to shut off power to multiple devices with a single switch. This is especially useful for managing electronics with standby power, such as TVs, computers, and kitchen appliances. Power strips can help you easily unplug multiple devices at once, ensuring that no unnecessary electricity is consumed when they are not in use.
Another strategy is to identify and target "energy vampires". These are devices that consume electricity even when not in use, such as those with standby power or constant displays. By unplugging these energy vampires, you can make a significant impact on reducing your electricity usage. For example, unplugging a device like a TV or toaster, or switching to LED bulbs, can make a noticeable difference in your energy consumption.
Additionally, consider investing in energy-efficient appliances and electronics. Many modern appliances are designed to minimize power consumption, even when plugged in. By replacing older devices with energy-efficient models, you can reduce the need for constant unplugging and still achieve significant electricity savings. Some utilities even offer financial incentives, such as rebates, for purchasing these energy-efficient alternatives.
Finally, you can combine unplugging devices with other energy-saving habits. For example, you can manually perform household tasks instead of relying on appliances. Hanging clothes to dry instead of using a dryer or washing dishes by hand can reduce electricity usage without requiring any devices to be unplugged. Similarly, adjusting your thermostat settings, especially when you are away or asleep, can help reduce the energy needed for heating and cooling, complementing your efforts to unplug other devices.

Use energy-efficient appliances
Using energy-efficient appliances is a great way to conserve electricity. Energy efficiency is about using technology to reduce energy waste, so you can still perform the same tasks but with less energy usage. Energy-efficient appliances can help you save money and reduce your carbon footprint.
When it comes to appliances, the U.S. Environmental Protection Agency's (EPA) Energy Star label is the gold standard for identifying the most energy-efficient options. This label can be found on over 75 types of products, including major appliances, lighting, and home electronics. For example, a refrigerator with the Energy Star label uses 35% less electricity than an older model, and replacing older appliances with energy-efficient ones can save a household around $450 per year.
There are also financial incentives offered by some states, such as tax credits or rebates, to encourage the purchase of energy-efficient appliances. These incentives can help offset the cost of investing in newer, more efficient appliances.
If you are not ready to replace your appliances, there are still ways to use your current appliances more efficiently. For example, only run your dishwasher and washing machine when they are full, as these appliances use a lot of energy to heat water. You can also reduce the temperature on your refrigerator and freezer to the recommended settings of 35°-38°F for the fresh food compartment and 0° F for separate freezers. Additionally, regularly defrost your manual-defrost freezers and refrigerators to maintain energy efficiency, as frost buildup decreases efficiency.
Small changes in your kitchen can also make a difference. For instance, using small electric pans, toaster ovens, or convection ovens for cooking smaller meals instead of a large stove or oven can save energy. Induction stoves are also a more efficient alternative to traditional electric or gas stoves, providing additional features and energy savings.

Seal windows and doors
Sealing windows and doors is an important step in conserving electricity and reducing energy expenses. Air sealing is the process of identifying and sealing any gaps or cracks where air can escape or enter your home, creating a more airtight and efficient living space.
To seal your windows and doors properly, follow these steps:
Identify Cracks and Gaps
Start by checking for any gaps or cracks in your walls, especially around windows and doors. Small cracks and broken seals on double-pane glass windows can allow heat and cool air to escape, increasing your electricity bills and carbon footprint. To identify these cracks, you can use a smoke-emitting object like an incense stick or a small open flame, as they are sensitive to drafts.
Choose the Right Sealant
The type of sealant you use will depend on the material and characteristics of your windows and doors. For insulating windows, silicone-based sealants are an excellent choice, while exterior grade sealants are ideally silicone-based due to their durability against the elements. Interior-grade sealants are usually caulk-based.
Prepare the Surface
Before applying the sealant, clean the area you wish to seal to ensure there is no debris or residue from previous sealing attempts. If you are using a caulking gun, cut the caulk at a 45-degree angle before placing it in the gun for a smooth application.
Seal the Cracks
Use the chosen sealant to fill in the identified cracks and gaps around your windows and doors. Ensure you follow the manufacturer's instructions for proper application and allow the sealant to dry completely.
Consider Additional Insulation
In addition to sealing, consider adding insulation to your walls. Options like fiberglass batts, blown-in cellulose, or foam board insulation can provide extra protection against heat loss. Make sure to clean and repair any damaged areas before installing the insulation, following the manufacturer's instructions for a tight fit.
By properly sealing your windows and doors, you can significantly reduce drafts, lower your energy expenses, and improve the overall energy efficiency of your home.
