The best estimate for a global average CO 2 emission factor from geothermal plants is 122 g/kWh from Bertani and Thain (2002). Recent CO 2

Electric Vehicle Myths | US EPA

Electric vehicles (EVs) have no tailpipe emissions. Generating the electricity used to charge EVs, however, may create carbon pollution. The amount varies widely based on how local power is generated, e.g., using coal or natural gas, which emit carbon pollution, versus renewable resources like wind or solar, which do not.
