What You'll Learn
Turn off lights and appliances when not in use
One of the easiest ways to reduce your electricity consumption at home is to turn off the lights when you're not using them or when you leave a room. This is because lights contribute to your overall electricity usage, and turning them off saves you money. While the exact amount you save depends on the type of bulb and the cost of electricity, turning off incandescent lights, in particular, is a good idea because they are the least efficient type of lighting. About 90% of the energy they use is given off as heat, and only about 10% results in light.
Similarly, it is important to turn off appliances when they are not in use. Even when switched off, household appliances can still use energy if they are plugged in, a phenomenon known as "vampire energy". Vampire energy can add up, accounting for 5% to 10% of residential energy use. Unplugging devices when not in use can save up to £80 per year on your electricity bill.
To make it easier to turn off your lights, you can use sensors, timers, and other automatic lighting controls. You can also use smart home technology, such as Wiser's Insights, to visualise your energy usage and identify problem areas. This can help you cement the kinds of behaviours that will lead to a reduction in your electricity bill.

Buy energy-efficient appliances
When buying new appliances, it is important to consider energy efficiency. Energy-efficient appliances use 10 to 50% less energy and water than standard models, saving you money and reducing your carbon footprint.
The US Environmental Protection Agency (EPA) and the Department of Energy (DOE) have introduced the Energy Star label to help consumers identify the most energy-efficient appliances. The label is found on washing machines, refrigerators, dishwashers, and heating and cooling units. However, not all Energy Star appliances are equal in efficiency, so it is important to compare models. Look for appliances that save at least 25% in energy consumption compared to your current models.
When shopping for appliances, keep in mind that a low price does not always mean low operating costs. Read the energy guide labels carefully to understand the energy efficiency of each appliance. You can also consult appliance buying guides, which offer tips on how to read energy guide labels and choose the most energy-efficient and budget-friendly models.
If you have old appliances that are still functional, consider replacing them with new, energy-efficient models. While the upfront cost may be higher, energy-efficient appliances often pay for themselves in a short time through reduced utility bills. For example, energy-efficient refrigerators have improved compressors, insulation, and temperature and defrost mechanisms, leading to lower energy consumption.
Remember to recycle your old appliances instead of donating them to ensure that energy-guzzling models are retired. Many stores that sell and install new appliances offer recycling services, and you can also refer to the EPA's online resources for responsible appliance disposal.

Insulate your home
Insulating your home is one of the best ways to keep your home warm and save energy. Even small changes can make a big difference. For example, putting insulation behind radiators or investing in double-glazed windows can significantly reduce heat loss and your heating bills.
Draught-proofing your windows and doors is another effective way to insulate your home. Professional draught-proofing can be costly, but there are cheaper DIY alternatives. You can also insulate your water tank, pipes, and radiators to save money on your energy bills. Additionally, consider insulating your attic, floors, and any crawl spaces to prevent heat from escaping.
Rugs can also help insulate your home by covering bare floors. Finally, remember to close your curtains at night to prevent warm air from escaping through the windows. These simple steps can help you save energy and reduce your electricity bills.

Reduce water consumption
Water is a precious resource, with less than 1% of the planet's water being liquid, drinkable freshwater. There are many ways to reduce your water consumption at home, which will not only benefit the planet but also save you money.
One of the easiest ways to reduce water consumption is to be mindful of your usage. Taking shorter showers, turning off taps when not in use, and only using the amount of water you need when cooking can all help. You can also reuse water, for example, by using leftover ice to water plants or collecting rainwater in barrels for your garden.
Upgrading to water-efficient appliances can make a big difference. Low-flow faucets, showerheads, and toilets use less water without sacrificing performance. Modern toilets use significantly less water per flush than older models, and you can also save water by only running full loads of laundry and dishes.
Leaks and dripping taps can waste a lot of water, so it's important to check for and repair any leaks regularly. You can also install a water meter to help you monitor your water usage and identify any leaks.
Finally, reducing your meat consumption can help lower your water footprint, as animal products, especially beef, require a lot of water to produce.

Install solar panels
Solar panels are an effective way to reduce your electricity consumption and lower your electricity bills. They work by converting sunlight into electricity, which can then be used to power appliances in your home or fed back into the grid.
Solar panels are composed of photovoltaic cells, which absorb sunlight and transform it into direct current electricity. An inverter then converts this electricity into alternating current electricity. To use solar power, you need to install solar panels on your roof, in your garden, or somewhere on your property where they are angled towards the sun.
While there are some drawbacks to solar panels, such as upfront costs and weather dependency, the financial and environmental benefits make them a worthwhile investment for many homeowners. On average, homeowners with solar panels can save around £450 a year in electricity bills, and if you export excess electricity back to the grid, you could make another £600 to £700 per year.
When considering solar panels, it's important to research your home's electricity needs and the necessary size of the solar power system. In some cases, solar panels may not be sized properly for the house, or their location and orientation may not be optimal, resulting in higher bills. To maximize the benefits of solar panels, try to use appliances such as washing machines or dishwashers during periods of high sunlight, and consider using energy-efficient appliances and light bulbs.
By combining solar panels with other energy-saving habits, such as unplugging devices when not in use and using a smart meter to track consumption, you can significantly reduce your electricity consumption and lower your environmental impact.
