"Nuclear Power Can Help the World's Poorest Get on the Grid."
Not really. The two great energy challenges of the immediate future will be reducing greenhouse gas emissions worldwide and meeting the moral obligation of helping developing countries gain access to the kind of reliable energy supply that allows for transformative improvements in health, education, and overall quality of life. Expanding nuclear power, which currently provides about 14 percent of the world's electricity, may appear to offer the best means of addressing each challenge without exacerbating the other. Eight African countries, in addition to already-nuclear South Africa, are exploring plant construction. Environmental scientist James Lovelock has asserted that nuclear energy "will give civilization the chance to survive through the difficult time soon to come."
The problem is that most of the world's new electricity demand is in the developing world, and about 85 percent of today's nuclear power is limited to the most economically advanced countries. The reasons for this are easy enough to grasp: Nuclear power's start-up costs are enormous, and large plants require a robust electrical grid -- prerequisites that are by definition out of reach for the estimated 1.6 billion of the Earth's 7 billion people who have little or no reliable access to electricity. Niger may be the world's fifth-largest uranium producer, but the cost of building a reactor to make use of it would take up more than half the country's GDP.
In recent years, many in the nuclear energy industry have touted small reactors as the solution to this problem -- modular units about one-fiftieth to one-third the size of the behemoths used in today's nuclear-powered countries and that can be scaled up gradually at far lower cost. U.S. Energy Secretary Steven Chu, who says he is a "big fan" of the technology, has urged Obama to ask Congress for $39 million to jump-start its development in the United States. But small reactors cost more per kilowatt-hour than their bigger siblings to keep up and running, and they still present most of the challenges that make nuclear power logistically difficult: the need for highly trained personnel to run them safely, procedures and facilities for safely storing nuclear waste, and protection against attacks, theft of radioactive materials, and sabotage.
All of this means that for people without electricity, renewable power sources such as wind and solar will continue to provide a better hope for plugging in quickly and cleanly, as will innovations in electricity storage, whether hydrogen-run fuel cells or some innovation yet to be produced.
