The average carbon dioxide emissions from conventional energy sources (coal, natural gas, oil) are roughly 0.92 pounds of CO2 per kilowatt-hour. Therefore, 10,000 kWh would result in 9,200 pounds of CO2, which is approximately 4.6 tons. Since none of the options exactly match this calculation, the closest approximate answer is 7 tons.
