Why can’t we just stack hydroelectric dams back to back in rivers to create tons of green electricity.
In: 2
Instead of one big dam, hundreds of smaller micro-hydro ‘leaky’ dams are better. If we can keep the height elevation within the range that salmon can jump, we can rejuvenate our salmon populations.
Its doesnt stop there tho. 99% of dams just ‘manage’ the water stored in the valley behind the dam, but there are ways we can turn the terrain itself into water storage by using level-swales, which are kind of like moats. India has made water available hundreds of villages doing this.
With these two techniques we can turn entire continents into water storage mechanisms, that create more fertile conditions, and provide habitat for salmon.
