Unreliable Nature Of Solar And Wind Makes Electricity More Expensive, New Study Finds

Michael Shellenberger

Solar panels and wind turbines are making electricity significantly more expensive, a major new study by a team of economists from the University of Chicago finds. Renewable Portfolio Standards (RPS) "significantly increase average retail electricity prices, with prices increasing by 11% (1.3 cents per kWh) seven years after the policy’s passage into law and 17% (2 cents per kWh) twelve years afterward," the economists write. The study, which has yet to go through peer-review, was done by Michael Greenstone, Richard McDowell, and Ishan Nath. It compared states with and without an RPS. It did so using what the economists say is "the most comprehensive state-level dataset ever compiled" which covered 1990 to 2015. The cost to consumers has been staggeringly high: "All in all, seven years after passage, consumers in the 29 states had paid $125.2 billion more for electricity than they would have in the absence of the policy," they write...MORE
