Answer your problems with hydropower !

Defending the hydropower as a form of renewable energy, I share this information about its increasement in global use.
There are some negative aspects associated with hydropower, but there are a lot of advantages too :
- Its cost is relatively low and competitive.
- It's flexible and adapted to demand.
- Reduction of greenhouse effect.
- Reduction of the reliance on oil. 
- Without environmental cost and risk.
The biggest disadvantage is the impact in the landscape because it requires to build large dams and reservoirs. But we have an answer for that : the micro-hydropower plants. They are a good solution to give energy to the most distant places.
