When a hydrocarbon fuel is burned, almost all of the carbon is the fuel burns completely to form CO2 (carbon dioxide), which is the principal gas causing the greenhouse effect and thus global climate change. On average, 1.850 kg of CO2 is produced for each kWh of electricity generated from a power plant that burns coal. A typical new household refrigerator uses about 700 kWh of electricity per year. Assume the electricity produced by the power plant is by burning coal. Determine the average production of CO2 due to the refrigerators in a city with 300,000 households. The average production of CO2 is
