Nuclear Fusion Unlikely to Challenge Solar, Wind Power

Even if it works, it will be expensive relative to alternatives

The world’s biggest and most expensive science experiment is likely to be threatened by the advance of renewable energy. Questions remain about whether the ITER nuclear fusion project will work at all, let alone provide electricity at anything like the cost of more traditional forms of clean energy. Solar power has plummeted 62 percent in the past five years, wind has followed a similar trend and even the best-case scenario would result in fusion being significantly pricier than renewables.
