CSIR Encourages SA Residents to take Control of Their Household Energy Use

Energy experts at the Council for Scientific and Industrial Research (CSIR) have noted that South Africans can reduce their household energy costs and possible grid outages by installing energy efficient devices and appliances, while also implementing alternative energy strategies.

At a media briefing held in Pretoria last week, CSIR principal researcher, Dr Jarrad Wright, along with his colleague, senior researcher Joanne Calitz, discussed a range of options available to reduce electricity usage in households, while also supplying household needs during load shedding or grid outages.

Wright said that shifting electricity demand by using electricity at different times of the day and week can also help to save significantly on electricity use and monthly household electricity bills.

“Moving the use of electricity around to different times of the day or week can help the power system significantly. At the same time, we need to continue to install energy efficient LED lighting, as well as energy efficient and smart appliances, such as fridges, washing machines, tumble dryers and dishwashers, while thinking of improving electric water geyser efficiency with geyser blankets and piping insulation.”

Wright also added that shifting to alternative energy sources would benefit the power system in its current constrained state and could, in some cases, reduce overall energy costs for the household.

“Clean burning cookstoves and increased use of your household braai would reduce the amount of electricity needed for cooking, while replacing your electric geyser with a solar water heater would assist in minimising the amount of electricity needed for water heating at times of high electricity demand,” he said.

Additionally, he urged households and communities to be careful when buying and installing any new appliances or technologies, and not just install them and assume that they will work perpetually. Making use of reputable suppliers and contractors will minimise the risk of housefires, electrocution and exhaust fume inhalation (from standby generators).

“Technology choices and system performance should always be verified and have a long-term dimension. When installing new equipment in your household, such as a solar photovoltaic (PV) unit, batteries, liquefied petroleum gas, standby generators or other new appliances, please ensure that a reasonable warranty and guarantee of workmanship are provided. Some form of service level agreement or maintenance contract keeping the systems in reasonable working order is recommended,” he said.

Lastly, Wright added “For solar PV or integrated solar PV/battery systems, some distributors allow for electricity to be fed back into the grid and households will be credited for this on their electricity bill. Households should see if this is possible in their area as it affects the optimal sizing of their system.

“Finally, reputable suppliers and contractors will usually be registered with parent associations, such as the South African Photovoltaic Industry Association, and should be certified as installers via appropriate quality assurance programs, e.g. the ‘PV GreenCard’.”

Green Building Africa promotes the need for net carbon zero buildings and cities in Africa. We are fiercely independent and encourage outlying thinkers to contribute to the #netcarbonzero movement. Climate change is upon us and now is the time to react in a more diverse and broader approach to sustainability in the built environment. We challenge architects, property developers, urban planners, renewable energy professionals and green building specialists. We also challenge the funding houses and regulators and the role they play in facilitating investment into green projects. Lastly, we explore and investigate new technology and real-time data to speed up the journey in realising a net carbon zero environment for our children.
