Electricity has become expensive worldwide. With Global Warming and Climate Change affecting our planet, it has become even more critical to reduce the amount of power that we consume in our homes and business. We look at ten easy ways to save electricity in the house.
Above all, there are many ways to save electricity. However, in this post, we look at the most effective ways to save power. Above all the electricity and the supply theretofore is in demand worldwide. With climate change being one of the driving factors.
Current Price Of Electricity In South Africa
Prices of electricity As of July 2018 Courtesy Of Review
- (0-50 kWh) is set at 90c per kWh Domestic Homes (Block 1)
- (51-350 kWh) will be 112c per kWh. (Block 2)
- (351-600 kWh) is set at 165c per kWh. (Block 3)
- ( more than 600 kWh) is set at 194c per kWh. (Block 4 )
A basic charge of R87 per month is payable per household.
Commercial users, prepaid and conventional, will pay a basic charge of R485 per month.
Converting Watts into Kilowatt Hours
To calculate the Kilowatt Hours of an electrical device one must confirm the wattage of the electrical equipment.
Once we know what the duration that the appliance is running and we know the watts produced we can calculate the amount of electricity consumed while switched on.
Formula to calculate electricity consumption = watts converted to Kilowatts x hours run time.
An Example on Standard 50 watt Down-lights
10 Down-lights @ 50 watts for 7 hour run time will be as follows.
500watts ÷ 1000= .5 watts now multiply .5 x 7 hours run time = 3.5kWh.
3.5kWh x 30 days @ R0.90 per kWh= R94.50 on 10 Down-lights.
An Example LED Energy Efficient Down-lights
10 Down-lights @ 3 watts for 7 hours run time will be as follows.
30watts ÷ 1000= .03 watts now multiply .03 x 7 hours run time = .21kWh.
.21kWhx 30 days @ R0.90 per kWh= R5.67 on 10 Down-lights
End Result LED lights run at 16.5 times less electricity. Makes you wonder how much we could have saved over the years.
Install LED Lights
As we all know lighting can pull large amounts of electricity. Most modern homes have many Down-lights. Additionally, most of the Down-lights are 40 watts or even 50 watts. As a result, a house with 30 Down-lights switched on will be consuming 1200 watts to 1500 watts an hour.
One can see that the amount of electricity wasted to supply lighting in the home. The LED lighting is 16.5 times more economical than conventional lights.
Energy Star Appliances Are More Eco-friendly
It is estimated that electrical appliances will draw as much as 20% of our electricity bill. Modern day appliances will save up to 50% on electricity.
Modern day appliances are far more energy efficient. As result of the world-wide energy crisis as well as Global Warming all major appliance manufacturers are pushing for the most efficient appliances in line with energy saving.
Turn Down Your Hot Water Geyser
Hot water geysers are the most prominent electricity thief in the home followed by Air-conditioners and heating. Hot water geysers will consume between 30% and 50% of the electricity in the house.
As a result, lowering the thermostat reduces the need for the thermostat to kick in as often, therefore, resulting in less loss. Another option that works well is switching off the geyser during the daytime. In most cases, this works well in winter as well.
Without a doubt, Solar Heating is one of the better ways to save electricity. Especially in South Africa where we have long hot days. Solar heating has come a long way in thee last few years.
In fact, as a result of the energy crisis worldwide solar power and many alternative energy sources are emerging. Above all, there are many solar energy advantages.
Fridge and Freezer
Reduce the amount of energy lost by opening and closing these appliances immediately. When the refrigerator or freezer is opened warm air rushes in immediately. As a result, the longer the device is open, the longer the cooldown time will be.
Gas Stove Are Far More Energy Efficient
Electric stoves are energy guzzlers. Have a gas stove installed and you will be shocked at the energy saving. Additionally gas is cleaner and less harmful to the environment.
Firing up the gas stove gives instant heat. So cooking starts immediately. Many electric stoves take a few minutes to reach optimum temperature. One of the best ways to save electricity is cooking on a gas stove. And the most significant benefit is load shedding does not affect a beautiful home cooked meal, especially in winter.
Install Solar Film on The Windows
As much as 20% of heat gain in the home is through the windows. Especially on hot days, the suns rays heat the house as the sun shines through. As a result, fitting Solar Film on the windows will reduce this heat flow substantially.
The solar film has up to 90% UV to stop the suns rays. Accordingly, the home will be more relaxed in the summer.
Install Heavy Curtains With Block Out
Heavy Curtains have several benefits in the home. In homes fitted with heavy curtains, one can expect the house to be cooler in summer and warmer in winter.
As a rule on hot summer days, curtains should be closed to stop heat flow into the home. Closed curtains will result in a cool house in summer.
Further more in winter the cold air is kept away from the interior. Accordingly, the curtains act as an insulation barrier between the cold windows and the curtains. The 75mm gap between windows and curtains is the insulation barrier.
Furthermore heavy curtains have an additional benefit of reducing noise pollution. In my opinion, heavy curtains are one of the more affordable home upgrades.
Fix Air Leakage In The Home
One of the most significant contributing factors to a cold home is air leakage. Above all air, leakage will result in a cold house with the potential for condensation and mold. Any form of heating will have an uphill battle against this monster.
In short most of the older steel window frames will have air leakage problems. Consequently one will have to seal these windows with a sealant foam. One of, the best places to find this will be Sondor.
If these windows do not seal correctly in this way, one would suggest masking tape on the inside of the window. Moreover, two or three layers will be better.
In essence, the tape is just to be fitted for the winter months only. As a result, the tape can be removed as soon as necessary.
Likewise, the wooden windows are also prone to air leakage. However wooden windows in most cases can be sealed correctly with window sealer. Once again Sondor would be the best bet.
Importantly remember that soft rubber with low memory and adhesive backing must be fitted. Additionally, doors are a leak factor as well. As a result, door sealing rubbers as well as a long door stop that will block cold air flow into the home.
Switch Off The Air-cons Switch On The Fans
First of all running an Air-con in the home on a hot summer day is throwing money away. As a cheaper option open doors and windows and run the fans. Moving air is cooler than fixed air.
Electric fans will require a fraction of electricity in comparison to running the air-con. In fact one of the best ways to save electricity is to reduce the need for heating and cooling.
Install Good Quality Roof Insulation
Roof Insulation is one of the benefits that is compulsory in all new homes. Moreover, homes insulated with SANS compliant insulation are far more energy efficient.
Did you know 35% of all energy in the home will be lost via the ceiling? As a result an insulated ceiling will have a substantial temperature improvement in summer and winter.
Furthermore, an improved temperature of 4-8 degrees will be achieved. Above all Roof, Insulation will reduce the need for heating and cooling substantially, especially in summer and winter.
Subsequently, homes insulated with roof insulation will recover the cost of heating and cooling in approximately three years as a result giving years of energy saving.
Furthermore, there are several roof insulation products on the market. To mention a few Aerolite Insulation a locally made insulation, as well as Isotherm Insulation, are the two leading brands in South Africa.
In fact of all the ways to save electricity roof insulation is probably the best.
10 Easy Ways To Save Electricity
Electricity is in demand. Our planet is under pressure. Climate change is real, and we are on a knife edge. Acquiring clean energy is high on the agenda with most countries under pressure to find clean energy.
With this in mind, we look at 10 Easy Ways To Save Electricity. Additionally, these 10 ways to save electricity will give us years of energy saving.
