Question 24Needs Grading

If you where transported 50 years into the future what do you think the power grid in the US would look like? Explain your reasoning.

Selected Answer:If i were transported 50 years into the future, I think the power grid in the US would be very eco-friendly. This is because we have already began to change everything to make it more "green", conserving energy and saving the environment.

Correct Answer:When a student asked our speaker this question during the FUTURES event on the main campus - he was told that is classified information.

I think you probably know as much as anyone what it will be like, but honestly I think there will be no grid except on the local level. The grid loses more electricity than it transports, so I hope we figure this one out. No answer is counted incorrect as long as you explain your answer with clear examples and justification in an orderly and complete way so that it is understood as to what you are proposing.

Question 1Needs Grading

Think about the Three Mile Island nuclear plant accident. The news media and many other nuclear energy supporters have said incident at Three Mile Island was not an example of nuclear facility failure. They say the incident shows how well our nuclear plants in the US work. Using the example of Three Mile Island take a position - do you support expansion of nuclear facilities in the US or do you want the expansion halted. Tell me where you stand and why using the Three Mile Island accident as your example.

(It is on page 222 of your book if you need a reference for review.)

Selected Answer:Personally, I do not support the expansion of nuclear facilities in the US. This is because they are very toxic and can be harmful to the air, thus harming many people.

Correct Answer:Oppose - well it costs too much to get electricity from nuclear energy - mining, wastes, and of course building and operating and eventually decommissioning are not included in the true cost of the power plant and the electricity generated. You should cite the amount of money needed to decommission and the overall emergency created by the accident to support this stand.

Support - the Three Mile Island incident did not expose people to harm, the safety systems worked, if you look at the other energy sources mining of resources, installation and clean up a nuclear plant has a much greater lifetime than a photovoltaic panel. Over the lifetime a nuclear reactor creates more energy in less time with fewer resources. The waste could be recycled but our government does not allow such reuse of nuclear materials.
