Question: how much electricity can a water turbine generate?
Answer: 5m x 14L/s x 9.81 x 0.75 = 515 watts of power. A 500W Hydro turbine may not sound very big, but it runs 24 hours per day, 365 days per year. It will produce around 4,000kWh per year and a reasonably energy efficient house will use about 5,000kWh per year.
