Conserving Electricity In Apartments: Simple Tips For Big Savings

Conserving electricity in an apartment is essential for both environmental and financial reasons. While some methods of reducing electricity consumption may require significant investments, such as replacing old appliances with energy-efficient models, there are also numerous simple and cost-effective ways to save energy at home. From adjusting daily habits to implementing small improvements, individuals can make a substantial impact on their electricity usage and bills.

Turn off lights and appliances when not in use

Turning off lights and appliances when not in use is one of the simplest ways to conserve electricity in an apartment. This practice not only saves energy but also reduces your electricity bills.

Firstly, it is important to develop the habit of turning off lights when leaving a room. While this may seem like a minor action, it can make a significant difference, especially if you have energy-saving light bulbs. Incandescent bulbs, in particular, should always be turned off when not in use, as they are the least efficient type of lighting, with 90% of their energy given off as heat. Halogens bulbs, while more efficient than incandescent bulbs, are still less efficient than CFLs and LEDs, so they should also be turned off when not needed.

LED lights are a popular energy-efficient option, using up to 90% less energy than traditional incandescent bulbs and lasting much longer. They are also unaffected by frequent switching on and off, so turning them off when not in use will help you save energy without impacting their lifespan.

In addition to lights, remember to turn off appliances when they are not in use. Many appliances, such as TVs, computers, and chargers, continue to draw power even when on standby, a phenomenon known as "vampire energy." Unplugging these devices can save you money on your electricity bill and reduce energy waste.

Finally, consider investing in smart home technologies, such as smart thermostats, which allow you to control your heating remotely and create personalised heating schedules. This can help you optimise your energy usage and reduce costs.

Switch to energy-efficient light bulbs

Switching to energy-efficient light bulbs is a simple way to conserve electricity in your apartment. LED (Light-Emitting Diode) bulbs are a popular choice, as they use up to 90% less energy than standard incandescent bulbs and could save you up to £40 a year on your energy bills. They also last much longer, so you won't need to replace them as often.

Another option is CFL (Compact Fluorescent Lamps), which are ideal for larger spaces. These bulbs use 60-80% less energy than traditional incandescent bulbs and can be recycled when they burn out.

If you're looking for a stylish option, smart LED lights are a great choice. They are not only affordable but also much more efficient than halogen bulbs.

When replacing old bulbs, it's important to choose the right type of energy-efficient bulb for your needs. Consider the size and lighting requirements of your apartment to determine the best option.

Remember to properly dispose of your old bulbs or recycle them if possible. Keeping your old bulbs in storage is also an option, especially if you're renting and plan to move out eventually. That way, you can take your new energy-efficient bulbs with you when you leave and reinstall the old ones.

Insulate your home

Insulation is an important way to conserve electricity in your apartment. It helps to reduce heat transfer by trapping tiny air pockets, keeping warm air inside during winter and stopping hot air from coming inside during summer. Proper insulation in walls, attics, and crawl spaces can reduce heating and cooling costs by up to 30%, resulting in significant savings on energy bills.

There are several types of insulation materials to choose from, each with its own advantages. Cellulose insulation, made from recycled paper products, is an eco-friendly, pest- and mold-resistant option. Fiberglass insulation is widely used due to its affordability and fire resistance, and it can be bought in pre-cut panels or blown into attics and hard-to-reach spaces. Natural fiber insulation made from biodegradable wool, cotton, or hemp provides good thermal resistance and is often treated with natural fire retardants. Rigid foam insulation, typically made from polystyrene, polyisocyanurate, or polyurethane, offers high R-values (a measure of insulation performance) in a thin package, making it ideal for exterior walls and concrete slabs. Spray foam insulation comes in open- and closed-cell varieties, with the latter being more expensive but offering a higher R-value and helping to block moisture.

To maximize energy savings, focus on insulating attics, as they are a prime spot for energy loss due to rising heat. In addition to attic insulation, you can also insulate water heaters to reduce heat loss and save on energy costs.

Before insulating your apartment, consider getting an insulation assessment by an energy auditor. They will inspect your existing insulation to ensure it is correctly installed and applied evenly between your walls. They will also check for any air leaks, such as holes where electrical lines run, and advise on draught-proofing measures such as using draught-excluders and adhesive strips for windows.

Be mindful of heating and hot water usage

Heating and hot water usage accounts for around 60% of the cost of energy bills. Therefore, being mindful of your usage can help you make significant savings.

Firstly, it is important to find a comfortable and consistent temperature for your home. Regularly turning the thermostat on and off can result in more wasted energy. A temperature between 18 and 21ºC is considered the best for most homes. If you are warm enough, turning your thermostat down by just one degree could save up to £75-145 per year on your energy bill.

Secondly, drafts from windows, doors, and other openings can cause your heating systems to work harder, increasing energy consumption. Sealing these air leaks with draught excluders, adhesive strips, caulk, or weatherstripping can improve energy efficiency, reduce your bills, and save up to £100 annually.

Thirdly, proper insulation in walls, attics, and crawl spaces can reduce heating costs by up to 30%, resulting in significant savings on energy bills. Insulating water heaters can also reduce heat loss and save up to £40 per year on energy costs.

Finally, unless you really need to wash clothes in hot water, use your washing machine's coolest temperature setting and always put in a full load. Rather than tumble-drying clothes, hang them on a clothes horse or rack to dry instead.

Unplug devices when they're fully charged

Unplugging devices when they are fully charged is an important step in conserving electricity in an apartment. This is because devices like TVs, computers, and chargers consume standby power, also known as "vampire energy", even when they are not in use. Unplugging these devices can save you a significant amount on your electricity bill.

While it may not be necessary to unplug your phone charger every time you're done using it, as the power draw is incredibly low, it is still a good habit to unplug any device that is fully charged. This is because some chargers may continue to send a charge to your device even after it is fully charged, which can be a fire hazard.

Additionally, unplugging devices can help maintain battery life. The Memory Effect is a phenomenon in older model batteries, specifically Nickel Cadmium cells (or NiCad batteries), where the battery holds less charge each time it is recharged. By only remembering the last charge, the battery stops being able to hold a complete charge. Therefore, it is advisable to unplug devices with NiCad batteries, such as rechargeable finger batteries, laptop batteries, and some handheld game console batteries, once they reach a full charge.

To make unplugging devices a habit, you can set reminders for yourself until it becomes a subconscious routine. You can also use tools like the Kill a Watt power meter to measure the energy consumption of different devices, helping you identify those with a substantial phantom load.
