Among the most efficient renewable energy resources are a. hydraulic and tidal generators b. solar cells and biomass generators c. wind and geothermal generators d. solar cells and hydrogen fuel cells 3. Of those listed, which of the following is the most efficient energy-transformation technology? a. automobile b. electric heater C. incandescent light d. fluorescent light 4. (three marks) If the overall percent efficiency of two connected energy-transformation technologies is 28% and one of the devices is 70% efficient, the other device has a percent efficiency of a. 98% b. 70% C. 42% d. 40% 5.If three connected energy-transformation technologies have efficiencies of 0.10, 0.30, and 0.50, the overall efficiency is a. 0.015 b. 0.030 C. 0.45 d. 0.90 6. The purpose of a cogeneration facility is to a. build two identical generators on one site instead of just one b. utilize the wasted energy from one generator in another process C. utilize the energy resource that is available in a particular location d. use renewable energy resources instead of non-renewable ones 7. The practice of local consumption involves a. consuming electricity from large centralized facilities b. utilizing a source of energy that is readily available nearby C. producing only the amount of electricity on which to subside d. making available electricity only to consumers in a small area Part B (Putting the Concepts to Work): Completion: Using your reading, answer the following Questions. Give your answer as well as your strategy for determining your answer. As part of your answer, give the page number in the reference material or the website that you used to find the answer to the question. 8. The transmission of electricity across low voltage transmission lines is efficient than using high voltage transmission lines. 9. Of generating stations using fossil fuels, nuclear, hydraulic, wind, and geothermal, the most efficient one is 10. When calculating the overall efficiency of an automobile, beginning with chemical potential energy in the crude oil and ending with kinetic energy of the moving automobile, there are a number of intermediate energy transformations that reduce the overall efficiency. Name three of these. 11. Determine the overall efficiency of a solar cell array (15% efficient) that generates electricity to operate a small electric motor (40% efficient). 12. Two energy transformation devices operate together with an overall efficiency of 0.40. If one device is 92% efficient, what is the percent efficiency of the other device? 13. The energy flow diagram pictured above shows three connected energy-transformation devices and their percent efficiencies. Calculate the overall percent efficiency of the energy transformation from energy input to energy output. 14. The energy flow diagram pictured above shows three connected energy-transformation devices and their percent efficiencies. Calculate the percentage of the original energy input that remains after each energy-transformation device, providing those values; A, B, and C pictured on the energy flow diagram. 15. Imagine you were asked to contribute to the province's or to the country's energy policy. What suggestions would you make?
