South Africa is still catching up with the rest of the world when it comes to renewable energy for transport, according to Carel Snyman, green transport senior manager at the South African National Energy Development Institute (Sanedi).
“The idea is still that vehicles need to be powered by oil. I know with new programmes like the Bus Rapid Transport (BRT) systems it is alternative transport. But this does not address alternative energy use,” he said.
Snyman said when it comes to burning energy inside an engine, there are major losses in terms of heat. Normal petrol-driven cars were not very fuel-efficient, with 64% of the fuel being used up in heat and only 20% going into the actual forward motion.
He added that alternative transport using gas and electricity had been discussed with their partners, so the seed to grow renewable energy in transport in South Africa had been planted.
