Telkom has announced that its CEO and executive director Sipho Maseko will step down on 30 June 2022. The telecoms company said the process to appoint a successor is well underway and a designated group CEO will be announced in the not too distant future.
It is possible that cooking oil prevented more looting in South Africa in the last week than the president, the ANC, the intelligence community, the army and the police combined. This, without question, says something about the versatility of the product. It says even more about the state of the state. When you are shown up by canola, you might want to revisit your strategy.ByHoward Feldman
Performance Media across Search, Social and Programmatic platforms is the single fastest growing area of digital media in South Africa. Combine that with the detailed analysis of campaign management, tagging and ad operations, and it becomes apparent that these highly specialist functions require a highly specialised unit.
The Transnet Port Terminals website has been hacked, implying that all companies under Transnet have been affected. All Transnet websites were down at the time when reporting was done for this SA Trucker article. The publication cited sources who requested to remain anonymous because they are not allowed to speak to the media.
Electric vehicles are often hailed as the solution to this quandary, but some question their environmental credentials. With much of the world’s electricity still produced from fossil fuels, the criticism goes that EVs may actually be responsible for more carbon emissions over their lifetime than combustion engine vehicles.
As German economics professor Hans-Werner Sinn put it in a recent controversial article, all we are doing is transferring carbon emissions "from the exhaust pipe to the power plant".
The assumptions underlying these claims are questionable. But even if true, this line of argument misses a key point. The car we choose to buy today directly influences the future of our energy system. Choose a combustion-powered vehicle and we lock in ongoing fossil fuel use. Choose an electric vehicle and we support the switch to a zero carbon society.
Due in large part to the high carbon-cost of EV batteries, the manufacturing process for an electric vehicle causes more carbon emissions than for a combustion engine vehicle. This means that the source of electricity used during the life of an EV is critical in determining how eco-friendly they are.

While two thirds of the world’s electricity is generated from fossil fuels, this proportion is decreasing rapidly. At least four countries are already at or close to being powered entirely by renewable electricity: Iceland, Paraguay, Costa Rica and Norway. Brazil is one of the ten largest economies in the world and they are at 75% renewable electricity. In the UK, the proportion of electricity provided by fossil fuels has halved over the last decade and is currently about 40%.
As the transition towards renewable electricity progresses, so too will the carbon footprint of EVs keep decreasing in step. This means that the superiority in carbon cost that electric vehicles already have over combustion vehicles, even if narrow now, will widen in the years to come.
Influencing the future
The electricity transition is only half the story. The production and purchase of new combustion vehicles locks in dependence on fossil fuel use for the life of that vehicle – just short of 14 years on average in the UK.
If the number of fossil-fuel-powered cars on the road stays high, it will be difficult to make serious headway in reducing transport emissions. In contrast, switching to EVs transfers energy demand from the transport sector to the electricity sector, allowing countries to more readily tackle the carbon cost of travel.
Progress in doing so is of course dependent on the speed at which industry and government decarbonise their energy supply. But the technology already exists to shed the grid’s reliance on fossil fuels, and many countries have committed to do so by 2050 or sooner. The distribution grid also already exists – we just need to install charging stations.

And in choosing where they source their electricity from, consumers are able to exert much greater influence on the energy transition than the present transport system that locks them into high-carbon lifestyles. Given that renewable electricity tariffs are already among the cheapest available, this could be a particularly potent force for decarbonisation.
The scale of the transition from combustion to electricity-powered transport is huge. Average household electricity demand could double once EV charging is included, and this will place extra strain on both the grid and energy bills.
But for those cars that we do use, EVs are the least bad option. The switch to electric vehicles needs to be seen as part of a broader shift in the way society is organised to tackle the climate crisis. That requires consumers, industry, and government to all play their part in creating a carbon-free future.
