Problem 1.1: Energy and Power
The purpose of this problem is to get a feel for energy and power ? the principle products of the electric utility industry. In answering the questions, be sure to cite your sources.
Part A: Suppose one takes a round-trip automobile excursion from Kuala Lumpur to Malacca. How much energy (in kWh) does the automobile require to make the trip? What is the average power consumption (in kW) of the automobile? How much does it cost ( in $, $/h and ¢/kWh) to make the trip?
Part B: How do the automobile excursion figures compare with Tenaga Nasional Berhad’s largest power plant? For example, how long would it take the plant (operating at maximum power output) to generate the same energy as the automobile consumes and at what cost (again in $, $/h and ¢/kWh)?
Part C: How quickly can a typical residential electric power customer purchase the same energy as the automobile trip consumes and at what cost (in $, $/h and ¢/kWh )? How does the automobile trip’s energy consumption compare with the monthly electric energy consumption of a typical residential customer?
Part D: How many automobiles does it take to consume the same power that the power plant of Part C produces when it operates at maximum power output?
Part E: How much energy does Tenaga Nasional Berhad produce each year? Suppose all of this energy could be produced by a single fictitious (but representative) oil-fired unit. How much oil would the unit consume? If this oil could somehow be evenly distributed over the surface area of Kuala Lumpur, how deep would the oil be?
