Scaling Up Solar: The Global Implications of a New
Study that Says Solar Power Is Cost Competitive
with Nuclear Power
Two US researchers have declared that solar electricity in their home state is now cheaper
than next-generation nuclear power. Olivia Boyd looks at their study – and its global implications.

The sunshine of North Carolina, a state on America’s Atlantic seaboard, has long been a draw for tourists seeking a little southern warmth on the region’s beaches. But holiday companies are not the only ones trumpeting a good local deal. The price of the state’s solar-generated electricity has fallen so far that it is now cheaper than new nuclear power, according to a report published in July by researchers at the state’s Duke University. The authors say their figures indicate a “historic crossover” that significantly strengthens the case for investment in renewable energy – and weakens the arguments for large-scale, international nuclear development.
Solar power is usually branded as a clean but expensive energy source, incapable of competing on economic grounds with more established alternatives, such as nuclear. The outspoken pro-nuclear stance adopted by a raft of iconic environmental figures – James Lovelock, Stewart Brand, Patrick Moore – has helped to instill in policy making circles the sense that this is the only power source that can restructure our energy supply at the pace, scale and price required by the pressures of rapid climate change. This study, which was co-authored by former chair of Duke University’s economics department John Blackburn and commissioned by NC Warn, a clean-energy NGO with a firm anti-nuclear bent, challenges that view. “This report should end the argument for risking billions of public dollars on new nuclear projects,” says Jim Warren, NC Warn director.
