Nigeria is experiencing nationwide power outages caused by poor electricity generation and distribution. Businesses and homes are relying on generators, but the rising cost of diesel is adding to the problems. In the past 10 years, its electricity grid has had 200 system failures. Despite having four refineries, Africa’s biggest oil producer does not refine its crude oil. Instead, it imports fuel. Nigeria’s current electricity supply is only 4,000 megawatts for a population of more than 200 million. As the electricity supply worsens, thousands of industries have stopped working, throwing millions out of their jobs. Al Jazeera’s Ahmed Idris reports from Nigeria’s commercial capital, Lagos.
