Answer:
Part a = The energy used by Japan from petroleum and other liquids is 44% of the total energy consumption. Let x be the amount of energy used by Japan in the form of petroleum and other liquids.
x = 44/100 x 21 quads
x = 9.24 quads
The amount of energy that Japan uses from other sources can be similarly calculated. The distribution is 4.62 quads of natural gas, 5.67 quads of coal, 9.24 quads of petroleum, 0.84 quads of hydropower, 0.21 quads of nuclear energy, and 0.42 quads of energy from other renewables.
Part b = The United States used 97.5 quads of energy in 2013 and had a population of 316.5 million people. The average energy use per million people in the United States can be calculated in this way:
average us energy use = total energy use/population
average us energy use = 97.5/316.5
average us energy use = 0.30 quads per million people
In Japan, a population of 127 million people used a total of 21 quads of energy. So the average energy use per million people in Japan can be calculated in this way:
average energy use for Japan = total energy use/population
average energy use for Japan = 21/127
average energy use for Japan = 0.16 quads per million people
The United States used approximately 0.30 quads of energy per million people and Japan used about 0.16 quads of energy per million people.
Part c = Fossil fuels are distributed unevenly because their formation requires precise conditions that aren’t found everywhere. For fossil fuels to form, they need to be subjected to anoxic (lacking oxygen) conditions that allow for great pressure, such as those found beneath the ocean floor.
