Au contraire, if we had winter and harsher weather, Kenya would be a more developed country. It has been argues in some sectors that Africa is less developed because of great weather all year round, requiring less effort to survive through it as food will be available almost through the whole year. This laxity is inherent to date where there is no incentive to come up with such stuff as reliable electricity
Not entirely sure I agree with this point. Various regions in Africa suffer severely from the weather -- specifically droughts and floods. Also, as various people on this thread have stated previously, there are plenty of reasons for providing a reliable electricity grid so I don't believe the "no incentive" argument holds. Check out Guns, Germs and Steel by (IIRC) Jared Diamond. It's quite illuminating in this respect.
