Energy 5: Global perspectives
Workshop goals:
• Analyze energy needs, resources, and costs for
LDCs, qualitatively and quantitatively
• Articulate your analysis strategies,
assumptions, and limitations
• Discuss specific needs, options, and
consequences
• Synthesize your learning in a brief team report
10 minute oral reports Tuesday or
1-page written reportsWednesday ?
Workshop activities
1. Choose your team and your nation (or
region). Discuss roles of team members.
Recorder? Time-keeper?
2. Compare each nation’s wealth to their energy
consumption. Calculate the growth of both
wealth and consumption. Discuss results.
3. Discuss a series of questions about the needs,
resources, and costs for each nation.
4. Compare your results with those of the other
team analyzing your nation (tomorrow?).
Wealth vs energy use
How can we calculate the GNP per capita in 2004 (G2004), given the GNP in
1992 (G0) and the growth rate from 1980-1992 (DG/G)?
Hint: Assume a constant growth rate, as a first approximation.
How many years does the given growth rate span? __
How many years have passed since then? __
Write down an equation to find G2004, if you know G0 and (DG/G).
Examples of growth
Simple example: If initial wealth G0=2 and growth rate was
50% during some time T,
what would wealth be at the later time T?
GT = G0+_____ = (___________)* G0
Mozambique example: GNP in 1992: G0=60 dollars per capita
Growth rate from 1980-1992: (DG/G)= -3.6 % over a time
period of T = ___ years
Growth rate from 1992-2004:
GNP in 2004: G2004=
Workshop and looking ahead:
Workshop:
• 1 hour for Activity 1 analyses.
• BREAK
• 1+ hour for Activity 2 discussions
Choices to make together today:
1. Tomorrow: Spend class time after debate on
• Discussing workshop results with other teams
• OR working together on calculus?
2. Workshop reports:
• 10-minute team oral reports Tuesday
• OR 1-page team written summaries on WebX Wednesday?
