- Estimate the annual carbon footprint (in lbs) of 1000 W Freezer operated 24 hours a day(assume 1 gal of crude oil generates 30 KWh and produces 40 lbs of CO2?Complete solutions. Need asapThe average American daily diet consists of 2,400 kilocalories. A kilocalorie contains 4814 J. Assume that this daily intake of kilocalories is completely metabolized at a uniform rate over a 24 hour period. What is the average power generation of the average American over the 24 hour period? Report your answer in units watts (W). I recieved 4814W per 24 hours but am unsure if I am correct.
