South Carolina
South Carolina’s greenhouse gas emissions have increased by 16% from 1990-2022, and the industrial sector consumes the most energy by end-use. Manufacturing is a major part of the state’s GDP, producing chemicals, motor vehicles, electronics, machinery, and more. More than half of in-state electricity is generated by nuclear, as South Carolina is the third-largest producer of nuclear power in the country.
