Solar energy is necessary for our transition to a sustainable economy, but a recent study in Geophysical Research Letters suggests that the industry may be harming the environment. Nitrogen Triflouride (NF3), a greenhouse gas used by the semiconductor industry to clean the chambers where silicon chips are produced, has 17,000 times the globe-warming capacity of CO2. Now researchers believe that emissions of the gas are up to 4 times higher than previously thought—perhaps as high as 16 percent.
