The concept of water footprints (amount of water used per person) can be extended to other resources as well. In this example, we will investigate the electrical energy footprint of various countries and the world. The following data is from the CIA World Factbook (https://www.cia.gov/library/publications/the-world-factbook), 2015.
We are interested in the amount of energy used on average by each person in the country. This is the “energy footprint per person” (which is the same as “energy footprint per capita”) for each country. Give your answers as decimal values rounded to 1 decimal place.
Of the countries listed in this question, which uses the most electricity?
