I believe this is based on the U.S. If wind power is as terrible as Brookings describes nationally, think of how much less efficacious it is in Maine where onshore wind is overall poor.
Hopefully the shallow thinking environmental groups will soon stop taking money from the wind industry and quickly acknowledge the reality they have been helping to destroy Maine's magnificence in shilling for this wholly fraudulent electricity source.
First—assuming reductions in carbon emissions are valued at $50 per metric ton and the price of natural gas
is $16 per million Btu or less—nuclear, hydro, and natural gas combined cycle have far more net benefits than
either wind or solar. This is the case because solar and wind facilities suffer from a very high capacity cost per
megawatt, very low capacity factors and low reliability, which result in low avoided emissions and low avoided
energy cost per dollar invested.
