As South Africans experience more cold fronts and severe weather, many households are grappling with rising electricity bills.
Local energy expert, Wes Reddy, has taken to TikTok to shed light on how various household appliances can cause dents in your wallet, offering insights and tips on how to help consumers save money.
His series of educational videos, often featuring practical tests and direct advice, has garnered traction from South Africans struggling with energy costs.
The hidden drain of tiny heaters
One of the most noteworthy revelations from Reddy's recent uploads shows the surprising expense of small fan heaters.
Reddy explained that tiny heaters consume approximately 2000 watts. If used for just one hour each day, they will use 2 units of electricity.
At a rate of R4 per unit, this amounts to around R240 per month. If you leave the heater on for four hours daily, the cost escalates to R960 per month. Extending usage to six hours a day could result in a staggering and eye-watering R1440 monthly expense.
Viewer comments further emphasise this issue, with one user remarking that R960 could instead purchase "a few extra blankets," a sentiment that Reddy agreed with.
Are electric blankets a good alternative for being warm?
But are electric blankets a warmer and cheaper alternative?
In contrast to the expensive fan heaters, electric blankets present a more energy-efficient option for keeping warm.
Reddy's video, "Electric Blanket Power Use: What It Really Costs You!", looks into the actual costs associated with using these blankets.
Electric blankets consume approximately 60 watts per hour, equating to 0.06 units of electricity. At a rate of R4 per unit, this translates to just 24 cents per hour.
So if you use your electric blanket throughout the night, the total cost amounts to only R1.92 per day, which adds up to R57.60 per month.
Chargers and 'phantom power'
Another common misconception is whether chargers consume power when not in use. Reddy's video, "Do Chargers Use Power When Not in Use?", explores the concept of "phantom power."
To investigate, Reddy plugged in three different cellphone chargers and a laptop charger, but ensured they were not connected to any devices.
When cellphone chargers are plugged in but not actively charging, they consume no power at all.
However, the laptop charger draws 0.03 amps at 230V, equating to 7 watts of power while idle. If this charger remains plugged in for 22 hours without use, it results in an unnecessary expense of R18 per month—simply for not unplugging it.

Elevate Her: Stand up for SA's forgotten women this August
This year, IOL aims to touch even more lives with it campaign to uplift homeless and housing insecure women across the country. Image: Hannah Gilbert We didn't know what to expect. We hoped people would care. What we didn't expect was for them to care as much as they did. In two weeks, we collected more than 300 dignity packs. Each one filled with items most of us take for granted — sanitary towels, roll-on, a toothbrush, socks, razors. Each one handed to a woman who was deeply grateful that someone thought of her basic need. The response humbled and overwhelmed us. Video Player is loading.

We saw our colleagues, across departments and cities, rally behind the cause as if it were personal, because for many of us, it was. Then there was Patricia Kaiser. She was the first woman we featured. A mother of four, living on the streets, longing to be reunited with her children. Her story reached someone who once sat next to her in class. That person reached out to us. And within days, Patricia was back in contact with the children who believed she was dead. We even helped reunite her with her eldest daughter, someone she hadn't seen in 27 years. All this, because someone watched a video. Because someone shared it. Because someone believed in giving a homeless woman a second chance. That is the power of storytelling. And that is the power of you, our readers, our partners, our community. This year, we are back with the second edition of Elevate HER. The need hasn't gone away. In fact, it's grown. And so has our ambition.

Burst manhole spews sewage near Greymont Bridge
On August 7, Ward 86 councillor Chantelle Fourie-Shawe was alerted to a serious issue involving a burst manhole near the infamous Greymont Bridge. The situation has now escalated to a public health concern, as raw sewage is reportedly bubbling up and flowing downstream, even reaching private property on Stellenberg Road. 'It's a health hazard, and a disgrace,' Fourie-Shawe stated. Read more: Pollution and sewage threaten Westdenes waterways The councillor was informed about the manhole burst by one of the civic organisations that monitor the rivers in the area. She emphasised that this incident highlights a troubling reality: The infrastructure in Johannesburg is crumbling before our eyes. 'This is symptomatic of a greater issue in the city, regarding the administration's failure to prioritise maintenance and repairs.' Fourie-Shawe expressed her frustration over the deteriorating state of the city's infrastructure, stating that such incidents are a constant reminder of the challenges she faces in her role. 'When I see this, this is what I always think about. This is why I am here, and why I fight.' She added that Johannesburg Water was alerted about the issue, sending an operations manager to assess and investigate the root cause of the repeated failures, so that repairs can take place.

Eastern Cape households reliant on subsistence farming ‘vulnerable to food insecurity'
A Rhodes University study finds that households engaged in subsistence farming in the Eastern Cape remain vulnerable to food insecurity, emphasising the need to broaden food security strategies beyond the agricultural sector. Subsistence farmers in the Eastern Cape are going hungry despite their farming activities, and researchers have called for a broadened food security strategy that goes beyond backyard gardens. Between March and September 2023, at least 447,000 people in the Eastern Cape ran out of money to buy food. Other statistics show mild to severe hunger in the province. Dr Kwena Frans Mothupi and Dr Reesha Kara, researchers at Rhodes University's Institute of Social and Economic Research (Iser), told Daily Maverick about their work on food insecurity among subsistence farmers in the province. Their study assessed the relationships between household agricultural activities, socioeconomic characteristics and food insecurity in the Eastern Cape. This was drawn from the 2023 General Household Survey. Primary findings were that households engaged in subsistence farming in the Eastern Cape remained vulnerable to food insecurity, and this emphasised the need to broaden food security strategies beyond the agricultural sector. Kara said that there was a shift from being dependent on agricultural produce or subsistence agriculture for food provision and food security to more reliance on income, mainly wages and social grants. Social grants 'are now used to provide food and I think for us this was a massive red flag because there was always this assumption that if you are farming at home, then you are food secure, but it turns out that results nationally show that this is not the case for many, many South Africans who engage in agricultural activities.' 'Multiple factors' Kara says multiple factors play into subsistence farming failing to provide enough food for households. 'People need land to engage in subsistence farming, but the need is more complex and deeper where additional support in terms of skills on farming is required… another really basic thing is access to water. Some people have space in their backyards to engage in subsistence farming, but then access to water is a problem.' Other factors include a decline in knowledge sharing of farming tactics, such as what type of vegetables grow in which seasons, and the availability of seedlings. Kara said that 'it gets even more complicated if we talk about the keeping of livestock and what does that mean in terms of land to graze; learning methods of grazing like rotational grazing; support for vaccines – and that prompted a whole study on markets that are available to support livestock farmers so they could turn this livestock into money.' Dr Mothupi said that 'from the research that we did, it is clear that agricultural households are the ones that are more vulnerable to food insecurity. If you look at other provinces like Limpopo, which arguably has the same profile as a province like the Eastern Cape – if you look at their food insecurity levels, they are a bit lower. In fact, I think they are the lowest in the country.' Mothupi is a postdoctoral fellow at the Iser/Future Earth Africa Hub Leadership Centre. 'There is declining engagement in agricultural activities, and that's why we need to look into solutions that look beyond engagement in agriculture. 'Our research shows that most of the agricultural households are doing those activities just to supplement their food intake, which mostly comes from those accessed by purchasing from the supermarket through grants and income. 'Households that have an unemployed member are twice [as] likely to experience hunger than the ones which have an employed member. So you can see that income really plays a big role in households achieving food security, rather than them being agriculturally active,' Mothupi added. Under the leadership of Prof Cyril Nhlanhla Mbatha, Iser focuses on multidisciplinary research across varied socioeconomic challenges in rural and urban spaces, locally, nationally and on the African continent. These include the use and consumption of agricultural land and environmental water resources, cross-border trade, rural to urban livelihoods, informal to formal economic sector activities, digital skills development and education issues for youth employment and productive activities. Mbatha said other factors that needed to be considered included questions such as, would the households have had anything to eat without subsistence farming, and what was their food security level before. 'I don't think we need to think that there's always one solution for a problem. A solution sometimes can be multipronged. The fact that we are encouraging gardening can also be supported by other interventions,' Mbatha said. 'The Department of Agriculture on its own can't solve the problem. You need (the Department of) Labour, DTIC, you need Treasury, you need Land Affairs. But the problem is that these government departments are working in silos. One department may not be enough to resolve these social issues.' DM
