Dirty Business: China’s Dominant Coal-Fired Solar Panel Industry Belches More Net Carbon Than Oil or Gas

The Biden administration has approved a massive solar power project in California that will produce enough power to electrify 90,000 homes. That’s the good news. The bad news is that producing the solar panels in China using coal-fired electrical power plants to generate electricity will produce almost as much CO2 as the fossil fuel plants the solar power is supposed to replace.

Manufacturing solar panels is a dirty business. Starting with the raw mineral quartz, the refining process produces a highly toxic substance, silicon tetrachloride, that some manufacturers simply end up dumping. Huge amounts of power and heat must be used to manufacture the photovoltaic cells.

Since most solar cells in the west are manufactured in China, that heat and power are generated by coal-fired electricity. Maybe someone should ask why we’re buying solar cells to save the planet from carbon pollution when the process of making them not only poisons the earth but dumps as much carbon into the atmosphere as energy produced solely by fossil fuels.

Wall Street Journal:

Producing a solar panel in China creates around twice as much carbon dioxide as making it in Europe, said Fengqi You, professor of energy systems engineering at Cornell University. In some countries or regions that don’t rely heavily on fossil fuels for electricity generation, such as Norway and France, installing a high-carbon, Chinese-made solar panel might not reduce emissions at all, Mr. You said.

“Yes, we are clean” in the West, said Mr. You. “But then the process of getting these panels from another country—China now, maybe somewhere else later—produces a lot of emissions.”

It’s true that after a few years of operation, a solar panel will eventually lead to a net reduction in carbon emissions compared to power generated by fossil fuels. But is the loss in efficient generation of power worth the difference? – READ MORE
