South Africans are fortunate to enjoy some of the world’s best weather, with many of our cities consistently ranked among the most pleasant.
However, in recent years, erratic weather patterns have raised concerns, as heatwaves, floods, and droughts become more frequent.
“We’re not imagining these changes,” says Mark Allewell, CEO of Sensor Networks. “Climate change is real, and globally, people are demanding action to mitigate its effects. In South Africa, the focus is heavily on energy conservation, given the many our energy supply and security.”
With more than 15 years of loadshedding, South Africans are acutely aware of their impact on the national grid. “We’ve adapted our behaviours out of necessity,” explains Allewell. “Our energy insecurity has led to innovative, bottom-up solutions. But while citizens have proven resilient, we need a coordinated, top-down effort to ensure long-term energy stability.”
European governments, facing similar concerns regarding their energy security (albeit very different weather patterns), found their solution in heat pumps, a technology that offers both heating and cooling more efficiently than traditional systems.
“Heat pumps are like magic,” Allewell notes. “They transfer heat from one place to another, even when it’s cold outside. The energy efficiency is staggering, producing more heat per unit of fuel than traditional methods.”
European governments quickly recognized the value of these heat pumps, offering subsidies for their installation. “Countries like France and the UK provide significant incentives for homeowners to install heat pumps,” says Allewell. “These programs help reduce long-term energy costs and support the environment. South Africa could learn from these initiatives.”
Despite South Africa’s ingenuity, we lack the same level of government support for smart energy solutions. “Our government has acknowledged the need for smarter solutions through regulations like South African National Standards (10400-XA),” says Allewell. “Yet, we’ve seen little in the way of incentives for technologies like heat pumps or smart meters, even though they could significantly reduce strain on the grid.”
South Africa has already experienced the benefits of incentives with the rise of solar power. “The tax incentives for solar installation were incredibly successful,” Allewell explains. “If we apply the same thinking to smart geyser devices, smart switches, home energy-use monitoring systems and other smart technologies, we could alleviate the pressure on our grid while also promoting a sustainability.”
Allewell believes the government needs to adopt proactive subsidy programs for energy-efficient technologies to ensure the long-term sustainability of South Africa’s power grid. “We need to borrow from Europe’s successful models and apply them here, combining smart technology with government support,” he asserts. “The future of our energy security depends on it.”
This approach, according to Allewell, would benefit both the environment and the economy. “By encouraging the use of energy-efficient technologies, we’re not just solving the energy crisis; we’re fostering innovation and creating jobs. It’s a win-win for everyone involved.”
As the climate continues to change, Allewell emphasises the importance of taking action now to ensure a sustainable future. “We owe it to ourselves and future generations to address power insecurity and climate instability. If we act now, we can keep South Africa’s weather as pleasant as possible and avoid making life more stressful for South Africans,” he concludes with a smile.
