Activity 1.2.2 Energy Distribution INTRODUCTION Have you ever considered where the electricity or natural gas that arrives at your home and other buildings comes from? Electricity and natural gas in the distribution grid is like several pipes contributing water to a pond. You might get water out of the pond, but once it is all mixed together, there is no way to know which pipe the water came from. You could measure the flow at each pipe and determine the percentage of water a specific pipe provides, but it is all still water in the pond. Energy that is inserted in the power distribution grid comes from several sources. DIAGRAM Turn each arrow in the diagram into a sentence. The diagram is attached to the Edmodo post as well. Example: 71% of petroleum provides 95% of transportation. 16 arrows means 16 sentences. Watch the following videos with the 7 conclusion questions in mind. Each video will take a class period. The due date for the activity will take this into account.
