As an example, Solyndra’s bankruptcy led to its abandonment of a cadmium waste storage facility in Milpitas, California, due to the facts that the facility was not financed by Solyndra’s federal loan guarantees and that Solyndra had not made much money prior to its bankruptcy.

We can check this claim by assuming that his plant would be similar to Mesquite Solar, one of the largest solar plants in the world, located in the Sonoran Desert. In 2018, Mesquite Solar 1, 2, and 3 generated 1.15 TWh, according to the U.S. Energy Information Administration, on a land area of 10 km2. In 2018, the United States generated 4,174.4 TWh of energy. Replacing this electricity would require 3,636 Mesquites with an area of 36,422.3 km2. In comparison, the state of Maryland has an area of 32,131 km2.
860
Using monthly generation data for Mesquite Solar plants from the U.S. Energy Information Administration, we can see the lowest and highest sixmonth periods of generation at Mesquite, and compare them to the same lowest and highest half years of generation of electricity in the entire United States. If 3,642 Mesquites provided all electricity, the worst six-month energy deficit, from October 2018 to March 2019, would have been 444 TWh. Overbuilding solar in this example by 30 percent would reduce this deficit to 16 TWh.
