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.

- 1) Heating the water in a 55-gallon water heater requires about 2.0 x 103 kJ of energy. a) Assume the energy came from natural gas with 80% efficiency; how many grams of natural gas are required? b) Assume the energy came from electricity with 80% efficiency and that the electricity was produced from the combustion of coal with 30% efficiency; how many grams of coal are required? For problem above, calculate how much CO2 in grams is emitted to the atmosphere. For a: Use the balanced equation for the combustion of methane (CH4) to determine how many grams of CO2are produced from the amount of natural gas required.
