Turn off unused electronics
Turning off unused electronics is a simple yet effective way to reduce electricity consumption. This is because even when turned off, plugged-in appliances and electronics quietly drain electricity. This is known as standby power, phantom power, or vampire power. It can account for 5-10% of residential energy use, costing the average household money and increasing carbon emissions.
To avoid this, unplug appliances and electronics when they are not in use. This is especially important for devices with a high wattage, such as TVs, computers, and kitchen appliances like coffee makers, ovens, and induction hobs. These appliances consume a lot of electricity when in use and can still draw a small amount of power when turned off but left plugged in.
You can also use power strips with switches to control multiple electronics, turning them all off at once when they are not in use. This is a convenient way to save electricity and reduce your energy bills.
In addition to turning off unused electronics, it is important to consider the energy efficiency of the appliances you purchase. Look for appliances with a high energy efficiency rating, as these will consume less electricity. For example, when buying a new washing machine, consider a model with a lower load capacity, as it will use less electricity and water. Similarly, when replacing a clothes dryer, choose an Energy Star-certified model, which uses about 20% less energy without sacrificing performance.
By turning off unused electronics and choosing energy-efficient appliances, you can significantly reduce your electricity consumption and save money on your energy bills.

Optimise lighting
Lighting is one of the most energy-intensive parts of building operation, so optimising lighting is a great way to reduce electricity consumption. Here are some ways to do this:
Firstly, replace old equipment with new, higher-yield equipment. For example, switching from incandescent or halogen light bulbs to energy-saving LED lighting systems can effectively reduce a building's energy consumption. LEDs use up to 90% less energy and last up to 25 times longer than traditional incandescent bulbs. They are also low maintenance, long-lasting, and environmentally friendly.
Secondly, install timers or scheduling systems to automatically turn lights on, off, or dimmed at predetermined times. This can reduce consumption by 2-45% and ensure lights are only used when necessary, minimising energy consumption during unoccupied periods.
Thirdly, consider adopting a smart lighting control system. These systems use sensors to adjust artificial lighting based on the amount of natural light available, also known as daylight harvesting. This can reduce electricity use by up to 40% by maintaining consistent illumination and taking advantage of available daylight.
Another strategy is to resize the lighting needs to avoid waste. This involves ensuring that all light sources are adapted to the right need and no more, which may include reducing the power of certain equipment and the number of lamps.
Finally, commit to regular maintenance to ensure longer service life. This includes changing lamps at the right moment and cleaning lighting reflectors at least once a year to avoid light and energy losses.
