Total Energy Consumption

The term energy consumption signifies the consumption of electricity. Energy consumption as electricity is a primary demand for households, factories, industries, complexes, and commercial places. According to a report, the total U.S. energy consumption for 2018 was 101 BTU (British Thermal Units). It accounted for 17% of the total energy consumption of the world. The total energy demand for the U.S. as oil equivalent was estimated to be about 6804 kg of oil equivalent.

Consider a 400-MW, 32 percent efficient coal-fired power plant that uses cooling water withdrawn from a nearby river (with an upstream flow of 10-m3/s and temperature 20 °C) to take care of waste heat. The heat content of the coal is 8,000 Btu/lb, the carbon content is 60% by mass, and the sulfur content is 2% by mass. How much electricity (in kWh/yr) would the plant produce each year? How many pounds per hour of coal would need to be burned at the plant? Estimate the annual carbon emissions from the plant (in metric tons C/year). If the cooling water is only allowed to rise in temperature by 10 °C, what flow rate (in m3/s) from the stream would be required? What would be the river temperature if all the waste heat was transferred to the river water assuming no heat losses during transfer? Estimate the hourly SO2 emissions (in kg/h) from the plant assuming that all the sulfur is oxidized to SO2 during combustion.
The enthalpy of combustion of benzoic acid (C6 H5 COOH) is commonly used as the standard for calibrating constant-volume bomb calorimeters; its value has been accurately determined to be −3226.7 kJ/mol.
