You Will Also Murmur; What A Harmonious World We Are Facing Now?
One should read this article:
Dams Are Being Blown Up All Over America, and That's a Good Thing Fewer of the structures mean healthier wildlife and cleaner water. And then. murmuring: What a harmonious world we have now, after the recent Paris Conference!

Dams Are Being Blown Up All Over America, and That's a Good Thing
Fewer of the structures mean healthier wildlife and cleaner water.
Vis-a'-vis the following one; and then murmuring what a harmonious world we have, after the Paris Conference:

The Hydro Dam Boom Could Devastate Tropical Wildlife
Nearly a third of the world’s freshwater fish species are threatened by hundreds of planned dam projects along the Congo, Mekong, and Amazon river basins.
Did you murmur, as I did? If not, go through the following link for a brief information in simplicity, about the hydro-power pros and cons and finding out how it is slowing down, in the USA, reaching to (Hydro power provides about 10% of the electricity in the United States. (1):)
http://water.usgs.gov/edu/wuhy.html
The most important factors overlooked on this link on the disadvantages statements, are huge evaporation and infiltration losses, from the water reservoirs behind the dams.
Also the slowing down of the hydro-power activities are well described in the following link and its diagram:
Reservoir construction is "drying up" in the United States

Gosh, hydroelectric power sounds great -- so why don't we use it to produce all of our power? Mainly because you need lots of water and a lot of land where you can build a dam and reservoir, which all takes a LOT of money, time, and construction. In fact, most of the good spots to locate hydro plants have already been taken. In the early part of the century hydroelectric plants supplied a bit less than one-half of the nation's power, but the number is down to about 10 percent today. The trend for the future will probably be to build small-scale hydro plants that can generate electricity for a single community.
As this chart shows, the construction of surface reservoirs has slowed considerably in recent years. In the middle of the 20th Century, when urbanization was occurring at a rapid rate, many reservoirs were constructed to serve peoples' rising demand for water and power. Since about 1980, the rate of reservoir construction has slowed considerably.
But the spread of the technology malady of building many inappropriate dams is already affected the entire world and hard to be cured.
Hopefully, in the future project-dams planning, the following two-cent concept to be considered, prior any decision on the go ahead:
