Among the essential sources of renewable energy, hydro has the lowest production costs. An advantage of small scale water plants is their low impact and disturbance factors for the environment.
offer you reliability of supply, they influence the reduction of dependence upon imported fuels whilst a legally-integrated national renewables market can offer the potential for profitable sales of surplus capacity. The typical water turbine for micro hydro power is the cross flow turbine (or OSSBERGER turbine, Michell turbine, Banki turbine). Isolated independent water plants are the preferred choice for renewable energy production for countries (partly) lacking a national power-distribution infrastructure.
