We have seen the price of electricity increase by about 300% in the last 5 or so years and there is no sign of any relief to come. So, what can be done?
There are many things the home owner can do, these range from relatively inexpensive to very expensive:
1. The quickest and least expensive is to replace old incandescent lights with the new LED ones – an average home should be able to reduce the lighting consumption by at least 60%. Payback on this investment will be about 1 year depending on how much you use the lights.
2. The next step would be to replace the electric geyser with either solar, heat pump or gas systems. These are more expensive, but will still pay for themselves within 5 years.
These two items alone will save the house owner about 50% of their total monthly account.
3. Swimming pool pumps consume anything between R500 to R1000 per month depending how long the pump runs for and the size of the pool. The pool pumps can now be replaced by solar ones. Again, the pay back is around 5 years. There are also solar covers available for pools which will block out all light to the pool and the pump can be turned off during winter months completely and the pool will remain blue and algae free when you remove the cover in the swimming season.
4. Roof insulation is a must – about 30% of heat loss in a house is through the roof.
5. Put some form of film on the windows, about 50% of heat loss is through them.
I hope this will give you some ideas on how to save on your electricity costs.
