1) Find five countries whose energy intensity is significantly greater than that of the United States. Is there an obvious explanation for their greater energy intensity? Any of these countries have anything in common? (Note: You may find territories of the United States listed as separate countries, but don't include them in your list.)

2) China has undergone rapid industrialization in recent decades, and its energy consumption has increased accordingly. What has happened to its energy intensity? Support your answer with a table or graph.

3) Find your state or country's per capita energy-consumption rate and compare it with the U.S. average of roughly 10kW per capita. What are some factors that might account for any difference?

4) Which of the U.S. or world energy-use categories in Figure 2.6 has shown the most significant change in its percentage of the total over the past few decades? Support your answer with data.

5) France has pursued energy independence through reliance on nuclear power. Explain and compare it with the graphs in figure 2.6

(3} Some 82% of U.S. energy comes from fossil fuels. The "Other\" category includes geothermal. wind, and solar energy. (b) Fossil fuels supply about 86% of the world's energy. Here the "Other" category includes biomass, geothermal, wind, and solar energy
