Energy efficiency involves using technology that requires less energy to produce the same results. This is key because it reduces greenhouse gas emissions and saves money for households and the general economy. As a way of encouraging people to develop good energy habits we recognise National Energy Efficiency Day on the 7th of October. We can all play our part with a little knowledge and a desire to make a difference.
So, what are some simple and effective steps to take that will optimise our energy consumption?
- The biggest energy guzzler in homes are appliances that use heat. Using an energy timer to regulate your hot water tank reduces the amount of energy used to warm the water. Geysers do not need to be on all day – they can be set to start heating just 90 minutes before use and automatically switch off shortly afterwards.
- Installing an electricity blanket around your geyser stops it losing heat.
- Taking shorter showers and setting your geyser thermostat to an optimal temperature such as 60 degrees Celsius will also help.
- Energy efficient appliances make a big difference and appliances are rated so you can easily check this when buying. Maintaining appliances also keeps them more energy-efficient.
- Using cold water in the washing machine and only washing full loads reduces consumption. Many modern detergents contain enzymes that actually work better in cold water.
- Wash clothes less frequently and hand wash and air-dry clothes as much as possible.
- Avoid the “rinse hold” and “heated drying” settings if you use a dishwasher – you can simply open the door once the dishes are clean and let them air-dry.
- Unplugging appliances that are not in use also saves power.
- Plan meals so that everyone eats together rather than re-heating food.
- Bear in mind that microwave ovens use less power than conventional stoves.
- Avoid the temptation to peek in the oven when baking, as more energy is required to re-heat the oven every time the door is opened.
- Let wet hair dry naturally or only use a hairdryer to style hair for a few minutes, rather than drying if from completely wet.
- Switching to LED lights is a no-brainer when it comes to saving electricity. They use up to 80 percent less energy than traditional incandescent bulbs and generate substantially less heat. Even just switching the main bulbs you use around the house will lead to noticeable savings.
- Where possible, invest in stand-alone devices that use solar power such as outdoor security cameras and lights, keyboards and calculators, rechargeable flashlights, tablets, speakers and cell-phone chargers.
- One big change you might consider is installing solar power panels to generate your home electricity. The initial cost of installation is high, but they last for 25 – 35 years.
- Spend less time on electronic devices and watching television. Not only will this save electricity it will improve your mental and physical health and is easier on the pocket!
