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,
1990 amounts:
Population: 2.5 x 108, growth rate: 0.6%
Energy: 3.2 x 108 kJ/yr/person, growth rate: 0.5%
Carbon emissions: 1.5 x 10-5 kg C/kJ, growth rate: -0.3%
Find:
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

Find1. How much energy we can save?2. How much coal (Kg) we can save?3. How much CO2 we can reduce?4. How many African children (1 liter/kid/day) we can support? Energy needed to treat water1. Average energy use for water treatment drawn from southern California studies is 652 kWh per acre-foot (AF), where one AF = 325,853 gallons. Thermal Energy in Coal2. The thermal power plants consume about 0.45 kg of coal per kWh. Energy output/fire power plant3. A typical 500 megawatt coal power plant produces 3.5 billion kWh per year. CO2 Emission4. Taking coal to contain 50 percent carbon, which combines with oxygen during burning to form CO2, we can arrive at 1.83 kg CO2 for every 1 kg of coal burned.arrow_forward
- Could you give me some explanation, the correct answer is at the bottom of the question.arrow_forwardIt has been suggested that carbon dioxide emissions should be taxed at $30 per metric ton (106 g C). Removal of CO2 from the atmosphere would be worth the same amount. Assume that the atmospheric mixing ratio of CO2 is 400 ppm. What is the value of the carbon in 1 cubic kilometer (km3) of air at Earth’s surface? Calculate the value of all the CO2 in Earth’s atmosphere? [Hints: The total atmospheric mass is 5.1480×1018 kg and it is composed of 80% N2 and 20% O2.arrow_forwardThe Saudi Arabian Oil Refinery developed an oil well which is estimated to contain5,000,000 barrels of oil at an initial cost of $ 50,000,000. What is the depletion charge during the year where it produces half million barrels of oil? Use Unit or Factor method in computing depletionarrow_forward
- Calculation of Energy saving We are given that Average energy use for waste water treatment = 652 KWh for 625,853 gallons Average energy use for 1 gallon waste water treatment = 652625,853 KWh Per day Average energy use for 29.522 Million gallon waste water treatment = 652625,853*29.522*106 Per day Average energy use for 29.522 Million gallon waste water treatment = 30753.29 KWh " Per day Energy saving = 30753.29 KWh " Finding How to come up with 30753.29KWh? If 652 KWh for 625,853 gallons 652,853*29.522*106 = ??arrow_forwardThe levelized cost of energy (LCOE) for coal-fired electricity is about $0.09/kWh. Suppose the capital cost of the plant is $600 million and it operates for 40 years with a capacity factor of 95%. What is the contribution of CAPEX to LCOE? Given the difference you (hopefully) find, what contributes the remaining costs?arrow_forwardQ2: A- Find the population of a city in 20 years from the year 2010 using geometric method, also find the capacity of water treatment plant required to achieve the consumption at that year if the average daily consumption is assumed to be 400 lpcd. year 1960 1970 1980 1990 2000 2010 population 58545 87817 131750 197625 296440 444660 B- By drawing illustrate a typical daily variation in water demand.arrow_forward

The difference in height between the reservoir's free surface and the stream is 70 meters. You come up with the concept of using this water to generate electricity. Create a power plant that gets the greatest electricity out of this resource. Also, look at the impact of electricity production on water discharge rates. What discharge rate produces the most power?arrow_forward
