When any fossil fuel is burned it produces emissions of carbon dioxide and water vapor. A typical household in a developed country will use approximately 70 kWh per month of electricity for computing and electronics. Each kWh of average coal burned produces 2.23 kg of carbon dioxide emissions while natural gas produces just 0.91 kg per kWh of carbon dioxide.How many more kg of carbon dioxide are produced by the coal plant compared to the natural gas plant from the computing and electronics alone, from a household over the course of one year?

Burning one gallon of gasoline in a car releases approximately 20 pounds of CO2 into the atmosphere.One person drives 60,000 miles in a car that averages 30 miles per gallon (mpg), while another person drives 60,000 miles in a car that averages 20 mpg. Over the course of the 60,000 miles, how many fewer pounds of CO2 are released by the 30 mpg car than by the 20 mpg car?
