Large hydropower is not sustainable - the northwest US is a great example: the large loss of salmon is KILLING the forests in the river headlands. Without the dams, salmon reached their spawning waters, and when they die, they are eaten - and that was distributing a HUGE amount of nutrients onto the land.

This is no longer happening, and the rivers cannot survive this loss.

Also, the salmon cannot survive either - the hatchery salmon are in no way a replacement for naturally hatched salmon. They simply don't survive as well, and are very different.

The rivers themselves cannot survive - they silt up. The Three Gorges Dam in China in particular is a long term nightmare.

We can think about small / micro scale hydropower, though. If we collect rain on the roof of a building, the water can be used to generate electricity without disrupting the critical water cycle.

And, we need to develop all the different renewable energy sources:

There are 12 countries that are leaders in renewable energy: https://www.clickenergy.com.au/news-...ewable-energy/
