One of the joys of living in a country in the developing world is the lack of dependable or consistent electrical power and water. Huge water tanks are the way around the water shortages. Power? At work there is no pain - we have a huge diesel-powered generator that kicks in automatically when the power cuts out. (UPS boxes keep computers going for that minute it takes the generator to kick in.) Yes, the photo is of that beloved generator.
At home? We use candles.
All of my friends in Tanzania have been without power for 12 hours of every day for at least a year now.
