Question

the average amount of energy used by each person is called per capita energy use. to calculate per capita energy use, divide energy use by the population. per capita energy use can increase or decrease depending on how energy use and population change:

• per capita energy use increases when energy use increases faster than the population. this can happen when technologies that use energy, such as cars and electronic devices, become more common.
• per capita energy use decreases when the population increases faster than energy use, usually because people use less energy to do the same activities.

between 1965 and 2015, how did per capita energy use change?
per capita energy use increased.
per capita energy use decreased.

Explanation:

From 1965 to 2015, technologies that use energy (like cars and electronic devices) became more common. According to the given information, when energy - using technologies become more common, energy use increases. Since per capita energy use increases when energy use increases faster than the population (and there is no indication that population growth outpaced energy use growth in this period), per capita energy use would increase.

Answer:

Per capita energy use increased.
