The goal is to visualize one kWh in terms of the amount of CO2 emitted during the generation of the electrical energy. Data for annual carbon dioxide emissions and annual total energy for electricity production were based off 2011 US numbers. The annual carbon dioxide emissions and annual total energy form a rate of mass, in grams, of carbon dioxide per energy, in KWh. It was found that each 12 oz. beverage on average can hold 2.0 grams of carbon dioxide for better taste. It was then possible to show that by dividing that rate of carbon dioxide per KWh with the carbon dioxide mass per can, three hundred 12 oz. cans is equivalent to 600 grams of carbon dioxide, which is produced per one kWh.
