Why Solar Is Much More Costly Than Wind or Hydro

Surprisingly, solar power fared poorly in the analysis, costing far more than wind power and nearly the same as nuclear power. The reason, says Gardiner, is that many of world’s solar panels are manufactured in China, where electricity is very carbon-intensive. The depletion of metal resources also represents a larger cost for solar than wind, she says. Gardiner notes, however, that solar technology is still improving and may be more cost-effective today than it was in 2012, the year used for the study.
