1. 1. How have the energy use patterns changed over the history of our country?
2. Which energy source became dominant in the late 19th century (late 1800’s) before being
overtaken by petroleum products in the middle of the last century?
3. What two other sources of energy rose quickly in the mid to late 20th century?
2. 4. The Industrial Revolution was a period from the 1850’s to the 1950’s where major
changes in agriculture, manufacturing, transportation, and technology had a major
effect on society. This is an image of the Industrial Revolution. What was the
Industrial Revolution and what do you think is the author’s message about it?
3. 5. Worldwide energy use has been increasing and is projected to keep on
increasing as shown in the graph below. Which sources of energy show the
greatest demand today?
4. 6. According to this passage, what might be the reason for the
significant change in population growth?
• The greatest single factor in the history of human population
growth has been developments in technology and the related social
changes that came from it. From the first development of tools to
the development of agriculture and the later rise of industry,
technology has expanded the resources available for the support of
large populations.
• Technological growth helps drive population which itself helps drive
technological progress. This is due to the ability of technological
improvements to increase the agricultural productivity of both
individuals and societies, and thus allowed for a boom in available
resources which provided sustenance for a larger population.
Furthermore, efficiencies in agriculture allowed people to pursue
other trades in academics and philosophy which helped set the
foundation for many more innovations to come.
5. 7. What does this
diagram tell you about
our human demand
for energy as we
became more
modern?
6. 8. The graph below shows an increase in CO2(Carbone dioxide) gasses that cause
Global warming. Using what you’ve learned from these pages, make a
connection between the Industrial Revolution, population growth, and the rise
in CO2 gasses.
7. 9. Look back at all of the pictures and graphs and get an overall idea of
what might have caused today’s energy problems. What do you
conclude are the causes of today’s energy problems? List as many
causes as you can think of.
What would be some solutions to these problems?
