Utilizing technology: trends in energy use
Example: world energy use (11.7) ÷ world population (1.24) = per capita ( 4 digit answer)
Analysis:
1.) consider the graph of world energy use from 1850 to 2000.
a. Describe the trend in world energy use.
b. Based on the trend, extrapolate the graph to the year 2050.
c. Explain why u extrapolated the graph the way u did. List the factors you considered
d. How certain are you that your projection of energy use from the present to the year 2050 is reasonable?
2. Consider the graph of world population from 1850 to 2000.
a. Describe the trend in world population.
b. Compare and contrast the trends on the graphs of world energy use and world population.
3.) Consider the graph of per capita energy use from 1850 to 2000.
a. Describe the trend shown in this graph.
b. Identify when differences to the general trend occur. Suggest a reason for differences to the general trend.
c. List some factors that influence per capita energy use.
4. Explain how the size of the world population affects on energy use.
