A study shows that claims about renewable energy’s high cost are demonstrably false.

The Wall Street Journal and Fraser Institute published the articles about solar and wind power Jan. 1, and Steve Hanley of CleanTechnica debunked the arguments with the help of Mark Jacobson, director of Stanford University’s Atmosphere/Energy Program.

Jacobson was the lead author of a paper that shows clean energy does not produce expensive and unstable electricity, as the articles claimed.
