(05.01, 05.06 HC) 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): © 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 The average amount of energy used by a U.S. household requires the burning of 15,000 pounds of coal per year. Calculate the kilowatt-hour of energy per year used by an average U.S. household. Calculate the amount of uranium (nuclear energy) that could be used to provide the same amount of energy. Provide reasoning for using uranium as an energy source instead of coal. Describe two methods for conserving energy around a home that could reduce energy use per capita for a household.

(05.06 LC) A person drives roundtrip 48 miles once a month to the farmer’s market to buy vegetables in his car that gets 24 miles per gallon. How much fuel could be saved if he grew his own vegetables instead of going to the farmer’s market?
