The immediate problem is poverty. Most of Africa is urbanising at a lower level of income than other regions of the world did. That means there's little money around for investment that would make cities liveable and more productive. Without upgrades and new capacity, bridges, roads and power systems are unable to cope with expanding populations. With the exception of South Africa, the only light rail metro system in sub-Saharan Africa is in Addis Ababa, Ethiopia. Traffic jam leads to expense and unpredictability, things that keep investors away.
In other parts of the world, increasing agricultural productivity and industrialisation went together. More productive farmers meant there was a surplus that could feed cities; in turn, that created a pool of labour for factories. But African cities are different. They are too often built around consuming natural resources. Government is concentrated in capitals, so is the money. Most urban Africans work for a small minority of the rich, who tend to be involved in either cronyish (有裙带关系的) businesses or politics. Since African agriculture is still broadly unproductive, food is imported, consuming a portion of revenue.
So what can be done？ Though African countries are poor, not all African cities are. In Lagos, foreign oil workers can pay as much as 65,000 dollars per year in rent for a modest apartment in a safe part of town. If that income were better taxed, it might provide the revenue for better infrastructure. If city leaders were more accountable to their residents, they might favour projects designed to help them more. Yet even as new roads are built, new people arrive. When a city's population grows by 5% a year, it is difficult to keep up.

“Energy independence” and its rhetorical (修辞的) companion “energy security” are, however, slippery concepts that are rarely though through. What is it we want independence from, exactly？
Most people would probably say that they want to be independent from imported oil. But there are reasons that we buy all that old from elsewhere.
The first reason is that we need it to keep our economy running. Yes, there is a trickle(涓涓细流)of biofuel(生物燃料)available, and more may become available, but most biofuels cause economic waste and environmental destruction.
Second, Americans have basically decided that they don't really want to produce all their own oil. They value the environmental quality they preserve over their oil imports from abroad. Vast areas of the United States are off-limits to oil exploration and production in the name of environmental protection. To what extent are Americans really willing to endure the environmental impacts of domestic energy production in order to cut back imports？
Third, there are benefits to trade. It allows for economic efficiency, and when we buy things from places that have lower production costs than we do, we benefit. And although you don't read about this much, the United States is also a large exporter of oil products, selling about 2 million barrels of petroleum products per day to about 90 countries.
There is no question that the United States imports a great deal of energy and, in fact, relies on that steady flow to maintain its economy. When that flow is interrupted, we feel the pain in short supplies and higher prices, At the same time, we derive massive economic benefits when we buy the most affordable energy on the world market and when we engage in energy trade around the world.
