Saving electricity at home is important for reducing energy costs and carbon footprints. There are many ways to save electricity at home, including using energy-efficient appliances, adjusting thermostat settings, sealing windows and doors, and changing daily habits. By implementing these strategies, individuals can lower their electricity bills and contribute to environmental conservation. Some specific examples include using a microwave instead of a conventional oven, washing clothes with cold water, turning off electrical appliances when not in use, and investing in energy-efficient upgrades.

What You'll Learn
Turn off electrical appliances at the plug
Turning off appliances at the plug is an effective way to save electricity and money. Even when switched off, appliances can continue to draw power if left plugged in. This is known as the 'phantom effect' or 'phantom load', and it can drive up your electricity bill over time.
Unplugging devices that are not in use can save you money and reduce your carbon footprint. Appliances that are particularly prone to using electricity when not in use include computers, modems, monitors, TVs, phone chargers, cable boxes, and gaming consoles. These devices often have standby modes, timers, digital clocks, or displays that continue to draw power.
To ensure that no electricity flows through an appliance, turn it off at the socket and pull the plug out. Alternatively, you can turn off the main power to the appliance at the consumer unit or fuse box. Smart plugs can also be used to control the flow of power to appliances and turn them off remotely.
When upgrading or replacing appliances, choose energy-efficient models that list their standby power usage. Older appliances tend to be less energy-efficient, so it may be more beneficial to replace them rather than repair them.

Use energy-efficient appliances
One of the most effective ways to save electricity at home is to use energy-efficient appliances. Modern appliances are designed to be more energy-efficient than older models, even if your usage habits remain the same. For example, a new fridge with the Energy Star label uses 35% less electricity than a fridge that is 15 years old. Energy Star washing machines use a quarter less energy and a third less water than standard models.
When shopping for new appliances, look for the Energy Star label, a voluntary program managed by the EPA. Energy Star-labelled appliances use about 10 to 40% less energy than other new models. The Energy Star website can direct you to rebates available in your area, and some state governments offer consumer rebates on Energy Star-rated models.
If you're looking to replace older appliances, Vista Energy recommends starting with appliances that are at least 15 years old, as older appliances waste more energy. You can also consider buying second-hand appliances, which can be more affordable and help reduce waste.
In addition to choosing energy-efficient appliances, you can also reduce your electricity use by being mindful of your daily habits and adopting simple energy-saving habits. This includes making sure to turn off appliances and electronics when they're not in use, using natural light whenever possible, and reducing your use of hot water.

Reduce air conditioner usage
Air conditioners are an important part of home comfort, but they can also be expensive. In the US, air conditioners consume 6% of all electricity produced, costing homeowners $29 billion annually. Air conditioning accounts for about 12% of monthly power bills, and as much as 27% in hot and humid states.
However, there are several ways to make your AC usage more efficient and lower those bills. Firstly, it is important to understand your AC unit's capabilities and tailor its use to your home's specific conditions and your lifestyle. For example, if you have pets or allergies, it is important to keep an eye on your filter as you may need to change it more frequently. A dirty filter could be the reason your AC is not cooling as well as it should. High-quality filters should be changed every six months and kept clean and free of debris.
Another way to reduce costs is to ensure your AC unit is not too big for the room. Use a room calculator to work out the best size for your space. If you have multiple rooms, it could be beneficial to buy multiple smaller units instead of one large unit. This will allow you to use more efficient models and lower your overall electricity costs.
Smart thermostats can also be used to reduce costs. These can be programmed to raise the temperature when you are not at home and lower it when you return. They can learn your schedule and adjust settings automatically, optimising energy use without sacrificing comfort. Features like remote control through smartphone apps and energy usage reports help you monitor and manage your consumption more effectively.
Finally, in warmer months when your energy bill is likely to be at its highest, unplugging devices and appliances that aren't in use can help trim your bill. If you are going on a week-long trip, unplugging AC units and other appliances can significantly reduce your energy bill while you are away.

Lower water heating costs
Water heating accounts for about 18% of a home's energy use and is typically the second-largest energy expense in any home. Here are some ways to lower water heating costs:
Reduce Hot Water Consumption
Reducing your showers by a couple of minutes is a great way to cut your water heating costs. Taking baths uses more water than showering, so consider reducing the number of baths you take. It is also recommended to only run full loads of dishes and laundry to make the most of the hot water you are using.
Lower the Thermostat Setting
Lowering the temperature on your water heater is one of the easiest ways to cut down on water heating costs. Most manufacturers set their water heaters at 140 degrees Fahrenheit, but the typical household only needs it set at 120 degrees. For every 10-degree reduction in temperature, you can save between 3% and 5% on your water heating costs.
Insulate Your Water Heater and Pipes
Insulation helps contain the heat inside your water heater, reducing gas and electricity consumption. Insulating the first 6 feet of pipes leaving your water heater can also reduce heat loss.
Install Water-Efficient Appliances
Many energy-saving insulation upgrades are now more affordable. Today's new appliances use half the energy of those from 20 years ago. Look for products with the Energy Star label, which typically use 10-40% less energy than other new models.

Switch to LED light bulbs
Switching to LED light bulbs is a great way to save electricity in the home. LEDs are highly energy-efficient, using up to 85% less energy than incandescent bulbs to deliver the same amount of light. This means that about 80% of the electrical energy is converted to light, while only 20% is lost to other forms of energy, such as heat. In contrast, traditional incandescent bulbs operate at only 20% energy efficiency, with 80% of the electricity being lost as heat.
LEDs are also long-lasting, with a lifetime of up to 100,000 hours, or 11 years of continuous operation, and 22 years if used for 50% of the time. This is a significant improvement over incandescent bulbs, which typically expire within a year. LEDs don't "burn out" like traditional bulbs because they don't have a filament. Instead, over a very long period of time, they gradually emit lower output levels and become less bright.
LEDs are also versatile and can be used in a variety of fixtures and settings. They can be used for table and floor lamps, wall sconces, outdoor floodlights, flat panels, and recessed lighting systems. They can also be dimmed and controlled remotely through smartphones or smart home systems, allowing for adjustments to brightness and colour temperature.
Making the switch to LED light bulbs is an effective way to reduce electricity costs and improve energy efficiency.

Frequently asked questions
Wash your clothes on a 30°C cycle instead of higher temperatures, and use cold water instead of hot. Only run your washing machine and dishwasher when they are full.
Use a microwave or toaster oven instead of a conventional oven, as they increase the temperature in your home. When using the stove, keep the lids on pots to reduce cooking time.
Take shorter showers, and use colder water instead of turning the heat all the way up. Swap one bath a week for a four-minute shower.
Turn off electrical appliances at the plug when you're not using them, and unplug phone chargers and other devices that draw power even when they're turned off. Keep your blinds or drapes closed on sunny days to prevent sunlight from heating your home.
