Your boss has asked you to evaluate the economics of replacing 1,000 60-Watt incandescent light bulbs (ILBs) with 1,000 compact fluorescent lamps (CFLs) for a particular lighting application. During your investigation you discover that 13-Watt CFLs costing $2.5 each will provide the same illumination as standard 60-Watt ILBs costing $0.25 each. Interestingly, CFLs last, on average, 9 times as long as incandescent bulbs. The average life of an ILB is one year over the anticipated usage of 1,000 hours each year. Each incandescent bulb costs $1.5 to install/replace. Installation of a single CFL costs $3.5, and it will also be used 1,000 hours per year. Electricity costs $0.3 per kilo Watt hour (KWh), and you decide to compare the two lighting options over an 9- year study period. If the MARR is 10% per year, compare the economics of the two alternatives based on the AW method.
