What You'll Learn
Turn down the thermostat
Turning down your thermostat is a simple yet effective way to reduce your electricity usage and save money. The key times to turn down your thermostat are when you are asleep or away from home for extended periods, such as during work hours. These are typically 8-hour stretches when maintaining a high indoor temperature is less important.
You can save as much as 3% for each degree that you turn your thermostat down during the winter. For example, setting your thermostat to 64°F while you're away instead of leaving it at 72°F will result in your furnace running less often, which will save you money. The lower the interior temperature, the slower the rate of heat loss, so the longer your house remains at a lower temperature, the more energy you save.
If you have a programmable thermostat, you can easily schedule temperature changes automatically. Programmable thermostats can store and repeat multiple daily settings (six or more temperature settings a day) that you can manually override without affecting the rest of the daily or weekly program. You can set it as low as is comfortable in the winter and then lower the setpoint when you're sleeping or away from home. Some smart thermostats even have occupancy sensors and will set back automatically when the home is empty.
However, it's important to note that turning down your thermostat too much when you turn on your air conditioner will not cool your home any faster and could result in unnecessary expense. A higher interior temperature will slow the flow of heat into your house, saving energy on air conditioning.

Install energy-efficient appliances
One of the most effective ways to reduce your electricity usage is to install energy-efficient appliances. While these appliances might have a higher upfront purchase price, they usually save you money on your electric bills in the long run.
When purchasing new appliances, look for the Energy Star label. These appliances are guaranteed to consume less energy than standard models. This includes refrigerators, dishwashers, stoves, and water heaters. For example, an Energy Star-certified heat pump water heater can save a household of four people $550 per year compared to a standard model.
If you're not looking to buy new appliances, there are still ways to reduce your electricity usage. For example, regularly defrosting manual-defrost freezers and refrigerators can help maintain their energy efficiency. Frost buildup of more than one-quarter of an inch decreases the energy efficiency of the unit. Additionally, keeping range-top burners and reflectors clean will reflect heat better, saving energy.
You can also reduce your energy usage by adjusting your thermostat. Lowering your thermostat by a few degrees during the winter can save you money on your electric bill. Remember to turn down your thermostat when you're not home and at night when you go to bed.
Finally, consider having a professional energy audit performed to identify areas where you can improve your home's energy efficiency. An auditor will inspect your insulation, furnace, water heater, and ducts to locate any leaks or areas where you may be losing heat and energy.

Reduce 'phantom load'
Reducing your exposure to phantom loads can significantly lower your electricity bill. Phantom loads, also known as vampire loads, refer to the electricity that devices and appliances use even when they are turned off or on standby mode. This happens because some devices continue to draw power from the grid when nominally off, with some claiming to be “switched off” but actually in a standby mode to power features such as clocks or allow for remote control power-on.
To reduce phantom loads, you can start by identifying appliances with standby modes, such as computers, TVs, printers, cable systems, and chargers. These devices can draw a significant amount of power even when not actively in use. For example, a laptop charger draws an average of 4.42 watts of power when left plugged in, which can add nearly $6 to your annual electric bill.
Once you've identified the sources of phantom loads, you can use smart power strips or power bars to manage them. These extension cords allow you to automatically or manually shut off power to devices that are only pulling a passive load. Alternatively, you can unplug devices completely to ensure they are not drawing any power.
When purchasing new devices, look for Energy Star-certified products. These devices are designed to use less power in standby mode, reducing your overall phantom load. Additionally, consider if you can switch off or get rid of any "always-on" appliances, such as an extra refrigerator, that may be contributing to your phantom load.

Insulate your home
Insulation helps to reduce heat transfer by trapping tiny air pockets. In winter, it keeps the warm air inside, and in summer, it stops hot air from coming inside. Insulating your home can save you up to 15% on your electricity bills.
To maximize energy savings, focus on insulating your attic, basement, crawl spaces, ductwork, pipes, and walls. Attics are often the most important area to insulate because rising heat makes them a prime spot for energy loss. Basement insulation helps prevent heat loss through your foundation and can also help fight moisture issues and water damage. Insulating ductwork, pipes, and HVAC systems can improve their efficiency. Insulating walls can be challenging, especially in existing homes, but it is crucial for comfort.
There are many different types of insulation materials, such as cellulose insulation, fiberglass insulation, natural fiber insulation, foam board or rigid foam, concrete blocks, and batt and roll insulation. The right type of insulation depends on your specific needs, location, and R-value. The R-value measures the insulation's performance, with higher values indicating greater effectiveness.
It is important to ensure that your insulation is correctly installed and evenly applied. You can consider hiring a professional auditor to inspect your insulation and identify any areas of heat leakage.

Switch to LED lighting
Switching to LED lighting is one of the most effective ways to reduce your electricity usage and lower your electric bill. LED bulbs for residential use can save up to 75% of the energy consumed by incandescent bulbs. Not only do LED bulbs reduce energy consumption, but they also have a much longer lifespan, lasting up to 25 times longer than traditional bulbs. This means you'll spend less money replacing them over time, making them a cost-effective and environmentally friendly choice.
When choosing LED bulbs, look for the ENERGY STAR certification. This label guarantees that the bulbs meet strict energy efficiency guidelines set by the US Environmental Protection Agency (EPA). By using LED bulbs with this designation, you can be confident that you're maximizing your energy savings.
In addition to choosing energy-efficient bulbs, you can also reduce your lighting-related electricity usage by adopting a few simple habits. Remembering to turn off lights when leaving a room is a great way to save energy. If you struggle to make this a habit, consider investing in smart lights or light switches, which can be controlled via smartphone apps or voice-controlled devices, making it easier to turn off lights remotely.
Another way to save energy with lighting is by using dimmer switches. Dimmers reduce the flow of electricity to the bulb, allowing lights to operate with lower power outputs and thus saving energy. Dimming outdoor lighting also helps reduce light pollution, which can have positive impacts on wildlife, human health, and climate change mitigation.
By combining the use of energy-efficient LED bulbs with conscious habits and smart technology, you can significantly reduce your electricity usage and lower your electric bill, contributing to both financial savings and environmental conservation.
