A home located in Texas, U.S. use 14000 kWh of electricity in 2021. The home is powered by a diesel generator, which requires 10000 liters fuel per year. The cost of fuel is $2 per liter. The annual maintenance cost of the diesel generator is $4000, and the cost of purchasing a new diesel generator is estimated at $10000. The annual maintenance fee for wind turbine is estimated at 20% of its total cost. The average wind speed is 6 m/s. Assume an effective lifetime for diesel system is 5 years and for wind turbine is 10 years. a. Design the required size of wind turbine to cover 80% of the annual electricity usage. b. Estimate the cost of wind turbine designed in section c for a one-year operation. c. Considering a hybrid system including diesel – wind system, calculate the average penetration and define the penetration class. d. Considering the cost of diesel generator, would you recommend using the above hybrid wind-diesel system? Assume the project life for 20 years. Please, describe.
