Environmental Engineering, disaggregation exponential growth question:
Consider the following disaggregation of carbon emissions:
Carbon emissions (kg C/year)= [Population] x [Energy (kJ/year/person)] x [Carbon (kg C/Energy (kJ)]
Using the following estimates for the United States and assuming growth rates remain constant,
a) The carbon emission rate in 2020
b) The carbon emitted in those 30 years
c) The total energy demand in 2020
d) the per capita carbon emission rate in 2020
We have been given the following data for year 1990:
Amounts in 1990
Growth rate (r) in %/yr
