Solar harms more than the environment; it hurts people—especially the economically disadvantaged, who face a hard choice between paying high energy costs or suffering energy poverty.
Consider a family of four in California’s Central Valley. They currently pay one of the highest rates for electricity in the U.S.—80% more than the national average.[14] They may be forced to choose between paying for daycare or turning off their air conditioner in 100-degree heat. Families like this are not rare. The California Public Utilities Commission says 3.3 million residential customers have past-due utility bills. Taken together they owe $1.2 billion.[15]
Adding more renewable energy to the grid is not only expensive; it’s dangerous! The North American Electric Reliability Corporation (NERC), a nonprofit organization that monitors the reliability, resilience, and security of the grid, says that the number-one risk to the electrical grid in America is adding more unreliable renewables.[16]
Recent events in Texas and California highlight the risk of adding more unreliable power sources to the grid. The blackouts were caused by several interconnected factors. The Texas power blackout in February 2021 left 4.5 million homes and businesses without power (some for several days) and killed hundreds of people.[17] The immediate trigger of the Texas blackout was an extreme winter storm, but that storm had such a massive effect because of factors rooted in poorly designed economic incentives. Texas wind and solar projects collected $22 billion in Federal and State subsidies.[18] These subsidies distorted the price of power and hence compromised the reliability of the Texas grid. The electricity market is complex. And multiple factors converged to cause the blackout including a failure of government oversight and regulation. But if investments had flowed to natural gas and nuclear power plants instead of unreliable solar and wind, the blackout would likely have lasted minutes instead of days.
Unreliable solar and wind power were also among the three primary factors causing California’s rolling blackouts in August 2020, according to the State of California’s final report on the power outages.[19]
A year later, in July 2021, Governor Gavin Newsom declared a state of emergency and authorized the use of diesel generators to overcome energy shortfalls. And in August 2021, the state announced the emergency construction of five new gas-fueled generators to avoid future blackouts.[20]
Events in California and Texas highlight another unappreciated cost of solar and wind: Compensating for their unreliability requires the use of more reliable sources of power, namely fossil fuels. A study conducted across 26 countries over two decades by the National Bureau of Economic Research (NBER) concluded for every 1 megawatt of solar or wind power installed there need to be 1.12 megawatts of fossil fuels (usually natural gas) as backup capacity because solar and wind are unreliable.[21] Moreover, using backup diesel generators and ramping power plants up and down to meet energy shortfalls are two of the worst ways to use fossil fuels; they’re inefficient and cause unnecessary pollution.
A final point: solar and wind have low power densities. According to a facts guide on nuclear energy from the U.S. Department of Energy, a typical 1,000-megawatt nuclear facility in the United States needs a little more than 1 square mile to operate. Solar farms, by contrast, need 75 times more land and wind farms need 360 times more land, to produce the same amount of electricity.[22]
Even if we could overcome all the practical constraints on storing, transmitting, and distributing solar power, supplying a country the size of the U.S. would require over 22,000 square miles of solar panels[23]—approximately the size of New Jersey, Maryland, and Massachusetts combined.[24] And the unreliability of solar power means that even with that many solar panels, we would continue to need most of our existing power plants.
