Question

The Tennessee Valley Authority’s coal-fired Kingston plant in Tennessee generates 10 billion kilowatt-hours a year by burning 13,000 metric tons of coal a day, supplying electricity to almost 700,000 homes. If all of the 7.7 billion metric tons of coal consumed worldwide in 2015 was converted to electricity, it would have produced approximately _____ billion kilowatt-hours of electricity. Assume the same efficiency as the Kingston plant.

    Answer:

    Approximately 16228 billion kilowatt-hours of electricity will be produced.

    Explanation:

    According to the statement, yearly energy production is directly proportional to amount of carbon to be burnt. Then, we proceed to estimate the yearly energy production from worldwide coal consumption (E), in kilowatt-hours, by simple rule of three:

    E = 10\times 10^{9}\,kWh\times \frac{7.7\times 10^{9}\,ton}{4.745\times 10^{6}\,ton}

    E = 16228\times 10^{9}\,kWh

    Approximately 16228 billion kilowatt-hours of electricity will be produced.
