Does electricity cause global warming?
Approximately 40 % of global CO 2 emissions are emitted from electricity generation through the combustion of fossil fuels to generate heat needed to power steam turbines. Burning these fuels results in the production of carbon dioxide (CO 2 )—the primary heat-trapping, “greenhouse gas” responsible for global warming.
