1) In 2010, the amount of paper recovered for recyclingaveraged 334 pounds for each person living in the US, according to the American Forest & Paper Association. The authors of the article reported that recycled paper can be incinerated with an average energy output of 16.29 MJ/Kg releasing 3.9x10^7 kg/CO2 a year. If the population in 2012 was 313,914,040, how much energy (MJ) can be obtained from incineration and how much CO2 (kg/year) may be released in that year?
2) How much of that energy (MJ) can be actually converted into electric power if the conversion efficiency is 23%?
