Textbook Question
Chapter 7.3, Problem 2TC
FIGURE E7-3 Corn prices have increased dramatically since corn ethanol has been added to gasoline
THINK CRITICALLY The percentage of ethanol in gasoline has reached 10% and is not likely to increase in the near future. Sketch a possible scenario for corn prices and the percentage of corn used for ethanol by continuing the graph in Figure E7-3 to 2030, and provide a rationale to support your projection. Your scenario should assume a constant-sized corn harvest.

Lastly, notice the yellow graph for "Net Exports": in 2008 it was about +400,
meaning the US exported 400 million gallons of biodiesel. But for the past
several years "Net Exports" has been in negative territory, meaning that we
IMPORT biodiesel from other countries! (this isn't surprising, notice that green
consumption is consistently larger than blue production). The US first started
importing biodiesel in the year

Recall that 1 kilogram is equivalent to 1,000 grams.arrow_forwardThe suggested time is about 22 minutes for answering this question. Where calculations are required, clearly show how you arrived at your answer. Where explanation or discussion is required, support your answers with relevant information and/or specific examples. Studies indicate that between the present and 2050, substantial growth in population and energy consumption will occur both in less developed countries (LDCs) like India and China and in more developed countries (MDCs) like the United States and Japan. The table below displays these projections. The increase in the global energy demand is expected to outstrip the energy available from the burning of fossil fuels. Describe TWO sustainable methods of energy production that can make a significant contribution toward meeting the future global energy demand.arrow_forward
