High Cost of 100 Percent Carbon-Free Electricity by 2040
Author: Orr, Isaac; Rolling, Mitch; and Phelan, John
Governor Walz’s proposal would cost Minnesota $313 billion through 2050 and lead to blackouts. Executive Summary Minnesota Governor Tim Walz’s proposal for a 100 percent carbon-free electric grid by 2040 will cost Minnesota families and businesses an additional $313.2 billion (in constant 2022 dollars) through 2050, compared to operating the current electric grid. Minnesota electricity customers will see their electricity expenses increase by an average of nearly $3,888 per year, every year, through 2050. According to the economic modeling software . . .

Author: Orr, Isaac; and Rolling, Mitch
[Summary] The Nobles wind farm has already been repowered after just 12 years in service. Repowering wind projects allows them to requalify for the wind Production Tax Credit (PTC), which expires after the first 10 years of a project’s life [“The primary motivations for partial repowering have been to re-qualify for the PTC” —U.S. Department of Energy (Land-Based Wind Market Report: 2022 Edition). Data from the U.S. Department of Energy shows that the wind facilities repowered in 2021 ranged in . . .

Author: Bessette, Douglas; and Mills, Sarah
Abstract Utility-scale wind energy is now the largest source of renewable electricity in the US. Wind energy’s continued growth remains contingent upon finding adequate resource potential and transmission capacity, along with communities willing to host turbines. While previous research on the social acceptance of wind has relied predominantly on case studies, resident surveys, and reviews of development practices and strategies, here we use a new method. We use a wind contention survey of energy professionals (n = 46) to assess . . .

Author: Overland, Carol
Minn. R. 7030.0400 is the MPCA’s noise rule, setting standards for industrial noise. It was developed to limit industrial noise, from a noise source on the ground to a “receptor” on the ground. ISO 9613-2 was also developed to measure ground based noise reaching a ground based receptor. A primary input is the “ground factor” set to address conditions on the ground, the ground effect, between the noise source and the receptor: 7.3 Ground effect (Agr) 7.3.1 General method of . . .
