Expanding the electric grid requires using SF6, a greenhouse gas.
"Used primarily in high-voltage electrical switchgear in electric #PowerGrids, SF6 is one of the most potent greenhouse gases on Earth. In the 21st century, atmospheric concentrations of SF6 have risen sharply along with global electric power demand, threatening the world's efforts to stabilize the climate."
#SF6: GWP = 24,300, Atmospheric lifetime > 1000 years
