Hydroelectricity is the world?s largest?and cleanest?source of renewable -energy. But despite lively interest in renewables generally, there is an information vacuum about the smallest version of the technology dubbed "the simplest, most reliable and least expensive way to generate power off grid."

Highly illustrated and practical, Microhydro is the first complete book on the topic in a decade. Covering both AC and DC systems, it covers principles, design and site considerations, equipment options, and legal, environmental, and economic factors.

Scott Davis has decades of experience operating, installing, designing, selling, and teaching about microhydro technology. An award-winner in the field, he currently works as a system designer and retailer with an alternative energy company for whom he has authored an on-line microhydro course.
