This guide is one in the Exploring Energy Efficiency and Alternatives (E3A): Micro-hydropower for the Home, Farm or Ranch series. Micro-hydro involves a large range of system sizes, from a 50-watt system powering an electric fence to a 100-kW system selling electricity to a utility. Like other renewable energy technologies, micro-hydro can be used with a grid-connected or an off-grid, battery-based system. This guide focuses on micro-hydro systems that are designed to offset energy consumption in a home, farm or ranch, not the sale of electricity for profit.
