- Please no written by hand solutions 1. List six primary public policy arguments for promoting renewable energy sources (RES). 2. From the list in question 1, choose two of the policy arguments and critically discuss the pros and cons for promoting renewable energy source.3. A construction company is considering purchasing a water pump to be used in dewatering a deep foundation cut. The Specific Electric Company sells two pumps in the 100-HP range. Model A-38 costs $2,400 and has a full load efficiency of 91%. Model A-40 costs $2,000 and has a full load efficiency of 89.5%. The construction company's excavation operation requires one 100-HP pump to operate a full load for 1,800 hours per year. Energy costs 2 cents a kilowatt-hour. (0.746 KW = 1 HP, and kilowatt-hours equals the number of kilowatts input times the number of hours of operation). These pumps are expected to serve 12 years and have 25% salvage value. If they are equal mechanically in all respects except efficiency, what selection should be made based on a rate-of-return analysis? Take MARR=12%.The city of Oakmont is interested in developing some lake front property into a sports park (picnic facilities, boat docks, swimming area, etc.). A consultant has estimated that the city would need to invest $3 million in this project. In return, the developed property would return $500,000 per year to the city through increased tax revenues and recreational benefits to the public. Whatwould the life of this project need to be in order to be cost-beneficial to the city? The interest rate on municipal bonds is 6% per year.
