While our country continues to battle the debilitating effects of load-shedding, one is left to wonder why we haven’t mobilised state resources to decrease the rate at which we use electricity in our homes.

Electricity minister Kgosientsho Ramokgopa has indicated interest in this opportunity and wants government to turn off our geysers when not in use to decrease the load on Eskom.

This rather bold announcement was met with a lukewarm reception — South Africans do not want to pay the price for the government’s failure to manage our national energy crisis effectively. That said, there is still some value to be extracted from Ramokgopa’s comment — we just need to be smart about it.

The average household geyser operates similarly to any household kettle, heating up repeatedly just to produce one cup of coffee. Unfortunately, this makes geysers extremely inefficient in terms of their energy consumption.

In fact, most of our electricity bills can be attributed to geysers, using up to 45% of total household energy usage. This is why Ramokgopa wants to be able to turn it off for you.

While this has raised the issue of our autonomy as citizens who have dutifully paid for a service that government simply cannot provide, there are some key takeaways we should consider.

Technology and innovation exist to help manage the energy consumption of our geysers more effectively. Why are we talking about turning the geysers off when we could be talking about turning a geyser’s temperature down during high peak periods, in a manner that does not affect customer convenience?

This technology is used worldwide to manage peak energy, so it’s not unique to SA. Yes, we are talking about smart home technology, and yes it may prove costly to roll this out nationally.

However, with government support and subsidies it could be possible. Living with load-shedding in perpetuity is not.
