A stainless steel recycling facility wants to be completely off the grid and supply their energy entirely via renewables. Their choice of renewable energy was wind coupled with energy storage. Since you are the expert engineer hired to help them, they ask you if they will need more than one wind turbine to supply the power they need. What is your answer to them (provide all calculations to prove them)?

You gather some information to perform your calculations. The facility is planning to heat up the stainless steel from an initial temperature of 25 °C and melt 1000 metric tons of material per day 5 days a week. The model of wind turbine to be used has blades that are 60 m long, the facility is at sea level and at a prime location where the wind blows 16 hours per day at 10 m/s and is run for 7 days per week. Also, the wind turbine has an overall efficiency of 40%.
