As we currently experience to great cost here in South Africa currently, where, due to a decade of neglected maintenance and capacity building brought about by a short-sighted government, rolling blackouts (euphemistically called "load shedding") are the norm, and diesel generation is brought to bear as a poor substitute for baseload capacity, at - as you may imagine - ruinous financial cost. Something in the region of USD400million a month for diesel fuel. Boy, are we in for some price hikes coming up!
