Confused by Numbers

The confirmation last week by South Africa’s super telescope, of the distance of the latest supernova found by Chile last year at 3.8 billion light years away is confusing. As the speed of light travels a little over 1 billion kilometers an hour, it is just a very long way away.

More down to earth figures of Citibank withdrawing SAA’s line of credit of R250m, I can get my head around. Even the universities needing an extra R3billion at a minimum is understandable, and probably R30 billion. The cost of the drought at untold billions, and then what about South Africa’s nuclear plans? Estimates were a trillion Rand, but since the Rand has crashed that has probably increased in cost by a couple of hundred billion or more. A billion here, a billion there, the numbers just don’t seem to be really understood by anybody. Even a Presidential jet at R4billion is a sort of understandable figure.

Is SA doing enough to combat climate change? COP 21 – Cover-up and/or opportunity

In 2011 at COP 17 hosted by South Africa in Durban, a flurry of activity installing solar water heaters into low-income homes took place to show to delegates attending the conference. Four years on and not only has the socio economic uplift low income solar water heating programme been dead for nearly 3 years, (targets missed by 500,000) but all incentives to encourage consumers to switch to solar from energy hungry electric geysers have also stopped. Indeed all other energy savings incentives such as energy efficient lighting, heat pumps, and other industrial scale saving programs have been in suspense or terminated.

Electricity and, as predicted, water crises, become reality: Opportunities for water conservation

Water saving measures has been largely ignored in South Africa. In much the same way as cheap electricity has lulled the public into a false sense of security, and consumer renewables in form of solar water heaters to replace electricity in heating water have been ignored, the current drought may force consumers both domestic and business to rethink water as a free or cheap resource.
