Two time zones for South Africa?

South Africa is considering two time zones. Imagine not having to wake up in darkness. Sounds good.  

Will it achieve its key objective: to save energy? A very recent study by the NBER pointed out that there is very little evidence of energy savings due to daylight savings time in Indiana, US.   Savings on light savings is lost to increased heating and cooling. See also related story on FoxNews

An internal study by Eskom concluded that up to 500MW can be saved. 

Let's think about this very carefully.
