Advantages of the hydro-electric power
The production costs once the installation is finished, are very low.
The regularity of the water flow allows a very effective installation with few spare batteries.
The constancy of the electric production is the major quality of the hydroelectricity.
The increase of the debit in colder period fits the increase of needs in energy (lighting and heating)
The global source of energy is unlimited and its utilization consumption does not affect the source, that is the water itself. Careful precautions must be taken on each site.
Inconveniences of the hydro-electric power
The installation can be a little more complex than the solar energy and the wind turbine if we want to minimize its impact on the environment. No more than 20% of the flow must be taken.
In cold countries, the stream can freeze and no more allow to produce some electricity, and can even cause damages in the installation.
