What You'll Learn
Turn off appliances and lights when not in use
Turning off appliances and lights when they are not in use is a simple yet effective way to conserve electricity at home. This practice not only reduces your energy consumption but also leads to significant cost savings on your utility bills.
Leaving appliances on, even when not in use, draws a small amount of electricity known as "phantom power" or "vampire power." This occurs because many modern appliances have features such as standby or idle modes, which continue to draw power even when the device is not actively in use. By turning off appliances when they are not in use, you eliminate this unnecessary power draw, reducing both your electricity usage and your utility costs.
Additionally, turning off lights when you leave a room is a fundamental energy-saving practice. While it may seem insignificant, the energy consumed by lighting can add up, especially if you have multiple lights on throughout your home. Turning off the lights when you exit a room ensures that electricity is only being used for illumination when it is truly needed. This simple action can make a notable difference in your energy consumption and can help lower your electricity bill.
To maximize your energy savings, consider combining this practice with the use of energy-efficient lighting solutions, such as LED bulbs. LEDs are renowned for their energy efficiency, using up to 85% less energy than traditional incandescent bulbs to produce the same amount of light. Unlike older fluorescent bulbs, modern LED lights are designed to handle frequent on/off cycling without significant degradation, so you don't have to worry about wasting energy or reducing the lifespan of your bulbs by turning them off when not in use.
By adopting the habit of turning off appliances and lights when they are not in use, you can make a substantial impact on your energy consumption and expenses. This simple action, combined with other energy-saving practices, can lead to notable reductions in your carbon footprint and contribute to a more sustainable future.

Use energy-efficient light bulbs
Using energy-efficient light bulbs is one of the fastest ways to cut your energy bills. Energy-efficient bulbs, such as LEDs, use significantly less electricity to produce the same amount of light compared to traditional incandescent bulbs. LEDs use up to 90% less energy and last up to 25 times longer than incandescent bulbs. This means that you will be replacing them less often, reducing waste and the environmental impact associated with bulb manufacturing and disposal.
When shopping for energy-efficient light bulbs, you will come across the terms "watts" and "lumens". Watts refer to the amount of energy used to produce light, while lumens measure the amount of light produced by the bulb. Essentially, lumens equate to the brightness of the light, and watts equate to the electricity used to create that light. You will also encounter the terms "brightness" and "light temperature". Brightness is self-explanatory, while light temperature refers to the warmth or coolness of the light, with warm light having yellow undertones and cool lights having blue undertones.
The cost of LED light bulbs has decreased since they first entered the market, and prices are expected to continue to fall as more products become available. While they are more expensive than traditional incandescent bulbs, they save money in the long run due to their longevity and low energy use. You can further reduce the initial cost per bulb by purchasing energy-efficient light bulbs in multi-packs.
To ensure you are choosing the most energy-efficient option, look for bulbs with an Energy Star rating. This certification indicates that the bulbs deliver the expected features while using minimal energy. Energy Star-rated bulbs can be used with controls such as timers and dimmers to save even more electricity.

Insulate your home
Insulation is a great way to conserve electricity at home. By reducing heat transfer, insulation helps keep warm air inside during the winter and stops hot air from coming inside during the summer. This lowers your heating and cooling costs and makes your home more environmentally friendly.
There are several areas in your home that you should focus on insulating:
- Attics: Attics are often the most important area to insulate as rising heat makes them a prime spot for energy loss.
- Basements and crawl spaces: Basement insulation helps prevent heat loss through your foundation and can also help fight moisture issues and water damage.
- Ductwork and pipes: Insulating ducts and pipes can improve your HVAC and water heating systems' efficiency.
- Walls: Insulating your walls can be challenging, especially for existing homes, but it is crucial for your comfort.
There are many different types of insulation materials, each with its advantages. Here are some common options:
- Cellulose insulation: This is an eco-friendly, pest- and mould-resistant option made from recycled paper products. It is typically blown into attics or wall cavities and treated with fire retardants.
- Fiberglass insulation: Fiberglass is widely used due to its affordability and fire resistance. It comes in pre-cut panels that fit between wall studs, attic rafters, and floor joists, or as blown-in insulation for attics and hard-to-reach spaces.
- Natural fiber insulation: Biodegradable wool, cotton, or hemp insulation is a popular choice for environmentally conscious homeowners.
- Foam board or rigid foam: This type of insulation is easy to apply and effective on exterior parts of the desired area. It acts as an absolute layer between the environment and the interiors of your home, reducing conductive heat transfer.
The amount of insulation you need and the specific type of insulation that is best suited for your home depend on several factors, including your climate, the type of heating and cooling system you have, and the part of the house you plan to insulate. To maximize energy savings, consider consulting a local insulation contractor or using the Department of Energy's Home Energy Save Calculator to determine the right amount and type of insulation for 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 at home:
Insulate your water heater and pipes
Insulating your water heater and the first six feet of hot and cold water pipes reduces heat loss and can save you money on your energy bills. The level of insulation depends on the area of your house, but generally, your attic, walls, floors, basement, and crawl space are the main areas where you should consider adding insulation.
Install low-flow fixtures
Low-flow showerheads and faucets can help conserve hot water by reducing the flow rate of water. Aerating showerheads mix air with water, forming a misty spray, while laminar-flow showerheads form individual streams of water.
Fix leaks
Leaking faucets can waste a lot of hot water, so fixing them is an easy way to reduce your hot water usage.
Shorten your shower time
Reducing your shower time can save a lot of energy. A four-minute shower instead of a bath can save a typical household around £60 a year on energy bills.
Use energy-efficient appliances
The biggest cost of washing dishes and clothes is the energy required to heat the water. Using an energy-efficient dishwasher and clothes washer can significantly reduce energy costs.

Buy energy-efficient appliances
When buying new appliances, it is important to consider energy efficiency. Many of today's appliances use half the energy of those from 20 years ago. When shopping for new appliances, look for the Energy Star label. These products typically use 10 to 40% less energy than other new models. Some electric companies and state governments offer consumer rebates on Energy Star products.
If you own your home, consider investing in a programmable thermostat. This can cost $100 or less and can cut energy consumption by 20 to 30% by adjusting the temperature throughout the day. The Department of Energy recommends setting thermostats to 68°F in the winter and 78°F in the summer.
If you are in the market for a new television, consider buying an Internet-ready television or a small add-on device such as Apple TV, Google Chromecast, or a Roku box. These devices use very little power compared to game consoles like the PlayStation or Xbox, which can use up to 30 times more energy.
When it comes to lighting, LED bulbs use up to 85% less energy than incandescent bulbs and last 15 to 25 times longer. Replacing the four most-used light bulbs in your home with LED bulbs can save you over $80 in electricity costs over their lifetime.
