Energy efficiency is one of the major campaigns going on in the world today and several world organizations, not only in the energy sector, but across different industries, have taken this seriously. Reducing the amount of energy required for production or to successfully render services has been at the forefront of these campaigns.
Being energy efficient by simply switching off a light bulb or having large solar panels installed in your house not only saves you money, but also has a positive impact on the environment.
For a whole country to be energy efficient it has to start from individual level, from our own homes. But what does it really take to have an energy efficient home? There are very many measures that when taken home energy efficiency can be achieved.
Switching to LED bulbs will save you up to 80% of lighting energy. LED bulbs also produce more light hence covering a wider area as compared to a regular bulb. LEDs will also lower your electricity bill.
|Light bulb projected lifespan||50,000 hours||1,200 hours|
|Watts per bulb (equiv. 60 watts)||10||60|
|Cost per bulb||Ksh395||Ksh50|
|KWh of electricity used over
|Bulbs needed for 50k hours of use||1||42|
LEDs versus regular bulb
Installation of motion sensors on security lights. The sensors are triggered by motion hence turning on the lights only when the path is being used.
Taking advantage of sunlight during the day, switching off excess or unnecessary lights and opting for solar light are also home energy efficiency measures.
Ceilings only might not be enough. Additional insulation is recommended on the walls of your house and also ensuring windows and doors are sealed properly to prevent cold air from entering the house. This means you will not need to use a room warmer often during cold weathers. The same insulation will make the cool air stay inside the rooms during hot weathers.
Opting for one fridge or freezer is advantageous.
The fridge doors should remain closed always and seals checked regularly to avoid the cool air from escaping since this might lead to use of more energy.
Vacuum the coils at the back of your refrigerator frequently and the refrigerator should not be located near the stove or oven.
Food should not be refrigerated when hot.
Do away with old appliances
Old appliances are less energy efficient because they tend to use more energy. This will save energy therefore lowering your electricity bills.
Well, its time you replaced your old kitchen appliances, computers, dryers, they are the reason behind that huge electricity bill at the end of every month.
Also not any new appliance will be energy efficient. Make sure you look for the Energy Star label on each appliance, the more the stars the more efficient it is.
Stoves and ovens
Always use burner according to pot size. This saves energy when the pot covers the flame completely.
Frequently clean the drip pans under conventional burners clean.
When using the oven, ensure the door seal is tight and the pot lids are used to cover the pots.
Use a microwave when warming food.
Keep your water heater warm. Having it at a temperature of between 110-135 degrees is warm enough rather than letting the water get too hot.
Use your washing machine when full to capacity.
Use dry lines instead of dryer and do ironing in large batches instead of ironing one or two clothes daily.
Avoid using too much detergent to save water.
Install a rain water collecting system
Energy efficiency does not only revolve around electricity alone. Water is also important and must be conserved. Collecting rain water saves your money. You will not only rely on the piped water therefore reducing your monthly water bill.
Unplug idle computers from the sockets.
Laptops are energy efficient, the use half the power a desktop computer uses.
Buy laptops rated 3.3V with lighter batteries.
