Global energy consumption has increased by almost 50% since 1970. In the last few decades, we have seen a significant increase in consumption by transitioning economies. According to International Energy Agency (IEA) via the World Bank, China's per capita use has grown by nearly 250 percent since 2000, India's by more than 50 percent, and Brazil by 38 percent. The map below shows the energy use per capita in 2015 (Figure 1): Map of the world is shown with varying shades of red to show energy use in kilowatt hours per person for the year 2015. The U.S., Canada, and Saudi Arabia used greater than 100,000 kilowatt hours per capita. Australia, Russia, and Kazakhstan used between 50,000 and 75,000 kilowatt hours per capita. China, Europe, Iran, Libya, and South Africa used between 25,000 and 50,000 kilowatt hours per capita. Mexico, Brazil, and Argentina used between 10,000 and 25,000 kilowatt hours per capita. India, Pakistan, and many regions in Africa used less than 10,000 kilowatt hours per capita. © Our World in Data 2020 Figure 1: Map shows the annual average per capita energy consumption measured in kilowatt-hours per person per year for the year 2015. Energy includes electricity, plus transport and heating. Use the map above to answer the questions: Identify one country that shows energy use per capita above 75,000 kWh. Describe one variable that could be contributing to the high energy use of the country identified in (i). Compare the energy use of a country that uses less than 5,000 kWh per capita with the energy use of the country identified in (i). Describe one possible reason for the observed difference in energy use. There are many ways energy conservation can reduce a country's energy use per capita. The table below shows conversion factors for different types of renewable and non-renewable energy. Use the table to answer the questions: Conversion Factors 1 kWh (kilowatt-hour) 3,412 Btu 1 pound of bituminous coal 12,000 Btu 1 cubic foot of natural gas 1,028 Btu 1 gram of uranium 40,000,000 Btu Th
