South Africa aims for 'zero carbon' buildings in green push
Bulelwa Makalima-Ngewana knows how much cash going green can save.
Four years ago, after signing up for "My Green Home" – an effort by the Green Building Council of South Africa to make buildings more energy efficient – her family saw their house in the middle-class suburb of Pinelands retrofitted with energy saving LED lights, low-flow showerheads and roof-top solar panels, as well as winter insulation.
As part of the green makeover, the family also learned to cut their energy use by hanging laundry out to dry rather than using a tumble dryer, switching off appliances that aren't being used, and switching to washing laundry with cold water.
