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 (G 2004 ), given the GNP in 1992 (G 0 ) and the growth rate from (  G/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 G 2004, if you know G 0 and (  G/G).

Examples of growth Simple example: If initial wealth G 0 =2 and growth rate was 50% during some time T, what would wealth be at the later time T? G T = G 0 +_____ = (___________)* G 0 Mozambique example: GNP in 1992: G 0 =60 dollars per capita Growth rate from : (  G/G)= -3.6 % over a time period of T = ___ years Growth rate from : GNP in 2004: G 2004 =

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?
