A University of Zimbabwe has shown that 61 percent of the citizens are not connected to the electricity grid. In turn, urban households are consuming four tons of wood for fuel per year. The statistic is nearly double that for rural households. As the power outages continue, those numbers are expected to grow. Zimbabwe has lost an average of 327,000 hectares of plantation forests and natural woodland per year between 1990 and 2010. There are currently only 15.6 million hectares remaining.
