Hydropower is a clean source of renewable energy that can also be cheap: it doesn’t require any raw materials to run, meaning the operating costs are low. On average, how much did it cost to produce 1 kWh (kilowatt-hour) of electricity from hydropower in 2018?$0.047$0.47$4.7

If the system produces 59,415 watts, what is the energy worth per day?  Assume electricity costs of $0.06 per kWh.
