Environmentally-friendly precursor for social development

Small hydropower plants are a precursor for economic growth and social development. They guarantee a local, stable power supply. Decentralized, small hydropower plants are often the only way to create environmentally-friendly power for electric lighting, for preparing and cooling food and for stimulating economic growth in remote regions.

In developing countries, they are a good substitute for diesel-powered generators. Even in industrialized nations, small hydropower plants are in demand, as they provide a useful contribution on the whole and effectively support energy change.
