This guide is one in the Exploring Energy Efficiency and Alternatives (E3A): Micro-hydropower for the Home, Farm or Ranch series. When most people think of hydroelectric power, they imagine the Hoover Dam or other large-scale installations, but hydroelectricity also works on a much smaller scale. This guide focuses on micro-hydroelectric systems designed for homeowners and agricultural operations to reduce use of utility-provided electricity, much like a small wind or solar electric system.
