Mini hydropower plants

When talking about large-scale alternative energy, hydropower plants are nowadays the most common ones. They give more than 80% of renewable energy in the world.
The hydroelectric energy is cleaner and more efficient than the one generated by fossil fuels. But it has some disadvantages like the environment disruption, the threat of dams breakage, the greenhouse gases emissions or the high cost of facilities...

The hydroelectric energy small system overcomes many of these disadvantages. Small hydroelectric projects are increasingly popular.
"Mini-hydroelectric" or "micro-hydroelectric" is the term to describe a hydroelectric energy system with a capacity of 100 kw or less.
Than can mean an excellent alternative energy source for residential use, affordable and efficient.
It´s needed a near water source that flows at least 2 L / min  from a high altitude.
The facilities are not very expensive (between 1.500-10.000 euros).

Besides, these micro-hydroelectric projects are used in many developing countries to carry electricity to remote places and improve their inhabitants quality of life.
