Prior to answering this question additional information is required, What HP and volt is the pump, what is the design head pressure and what is actual head pressure. what is the application of the pump. I work energy efficency and recently installed VFD's on 3 larger garden pond circulator/filter pumps. With programming we reduced yearly energy consumption by 1,850,000 watts. with local energy rebates this upgrade was close to free.
You can use Solar Pumps: Solar-powered pumps perform well in climates with a great deal of sunshine and save money by not requiring an outdoor electrical outlet. Solar pumps also work well if your fountain is located a distance from the power supply. However, flow rate is minimal compared to typical voltage
