Although China may be a cheaper place than Europe for producing solar panels, the savings come at a higher cost to the environment, a new study says.
Weaker environmental standards and the more highly polluting sources of energy used by Chinese manufacturers are the reasons for the discrepancy, according to research by Northwestern University and the United States Department of Energy’s Argonne National Laboratory.
Researchers from the Illinois-based institutions looked at the carbon footprint and energy usage of making solar panels.
Their analysis tallied the costs at every step of production, including the mining of raw materials, transportation and the factory’s power supply.
