One man’s failed attempt to build a transmission line illustrates a unique American obstacle to clean energy.
The cost of wind energy has dropped drastically over the past several decades as the technology has advanced, especially in the size of turbines. Since 2009, the unsubsidized average cost of onshore wind-energy production has fallen to 4.2 cents per kilowatt hour, from 13.5 cents in 2018, according to an analysis by Lazard, the company I work for. After including U.S. tax subsidies, the cost of building wind capacity is often lower than the marginal cost of generating electricity with existing coal-powered plants. Thus wind energy now offers great opportunities for lowering carbon-dioxide emissions.
