The use of materials high tech rare earth type in the field of renewable energies is not a story on the net but a reality.
I cited neodymium as a simple example, the overall idea is that renewable or not, you need classic or exotic materials to develop this kind of technology and it is therefore very exaggerated to speak of "energy. green ".
Are the large hydraulic dam dismantled 20 years after their construction? very old hydraulic plants continue to produce and will produce for a long time
The example of large dams is poorly found, because the ecological changes they generate are gigantic, worse even than nuclear power plants.
The largest dam in the world, that of the 3 gorges located in China on the Yangzi Jiang, required the displacement of 1,2 million people (!), More than 15 cities and 100 submerged villages (which had to be relocated = rebuild elsewhere) and incidentally 4million m3 of concrete ...
Closer to us the construction of the dam From Aswan on the Nile has largely contributed to the use of pesticides due to the drastic drop in alluvial deposits, the result in the river delta is quite worrying.
no one will worry if we extend the life of wind turbines! less dangerous than extending the life of nuclear power plants ... the worst thing that can happen to a wind turbine is to fall ... and there is never anyone below on windy days
Wind turbines are indeed preferable to nuclear, but in the current framework, ENR plays the role of supplement to all energy sources to continue in the worst ...
