If the system costs $88,792, how many years would it take to pay off the investment?  Assume the energy is worth $104 per day.  Assume there are 328 operational days per year (the rest are maintenance days).

If the system produces 66,185 watts, what is the energy worth per day?  Assume electricity costs of $0.08 per kWh.

A coal fired power plant has a life of 30 years. It generates an average of 3000 GWh of useful electricity per year. The EROI (Energy Return on Investment) of the electricity generated from the coal power plant is 15. How much total input energy does the power plant consume annually? 200 TJ 720 TJ 450 GJ 500 GJ

A machine is purchased for $60 000. It is estimated that it has a useful life of 5 years and will then be sold for $5000. Using the straight-line method, calculate the amount of depreciation to be charged for each year of useful life.Group of answer choices$5000$12 000$0$11 000

A machine that cost $400,000 has an estimated residual value of $40,000 and an estimated useful life of 20,000 machine hours. The company uses units-of-production depreciation and ran the machine 3,000 hours in year 1, 8,000 hours in year 2, and 6,000 hours in year 3. Required:Calculate its book value at the end of year 3
