1. For a proposed wind turbine, the following table presents the expected cash ows over life cycle. For that type of wind turbine, it has been observed that the service life is l 1 years 25% of the time, 12 years 30% of the time, 13 years 40% of the time, and 14 years 5% of the time- Round off the expected value of the service life to the nearest whole number, and consider this as the analysis period. Is this a good investment? Assume 4% discount rate. Year incurred Year 0 Annuall Annuall Rehabilitation cost $1M at year 5 Periodic, as indicated $2M at year 10 Salvage value of recyclable parts $3M End of the analysis period Cost of disposing of unsalvageable parts $0.5M End of the analysis period Revenue from the sales of electricity $8M Annually _enerated b the wind turbine
