Hydro is used a lot, to the point where habitats are getting destroyed and species are getting rekt (see the yellow river dolphin). China has a lot of hydro for example. That's why ecoterrorists bomb dams. Still better than fossil fuels, habitats are temporary but carbon is forever. Solar, wind and biofuel are the only moral ways of energy generation so far.

Hydropower is sort of bad for the environment due to the dam causing the vegetation it floods to rot, releasing a lot of greenhouse gasses (mostly methane). So it's not even "clean energy". http://www.climatecentral.org/news/hydropower-as-major-methane-emitter-18246

And ignoring that little fact, it COMPLETELY fucks up the entire eco system both below and above the dams.

Hydro has been exploited about as much as possible in most of the west, and geothermal is only possible where the subsurface temperature gradient has certain properties. You'll see geothermal grow more than hydro but less than solar and wind over the next 10 years.

In the simplest terms, imagine putting a turbine on top of Old Faithful. There's areas where you can easily extract a lot of heat from the ground, just add water and a turbine, and you got a power plant.

Hydro is great if you don't care about the environment around whatever you're damming, have a ton of money to pay for building it, and have a location you can do it at. Other sources (except nuclear) are pretty cheap to start up, can be built anywhere and don't fuck things up so obviously.

Most of these things are just a matter of politics.

If you had certainty that the objectives, goals, and wealth distribution of your society would stay exactly the same for 200 years then it would make sense to build a trillion hydro dams and wind turbines, then switch all cars to electric ones.

Thing is, politics its extremely unreliable, whos putting the money? who will profit from the energy generated?

If you consider the actual capitalistic evil society who is ok with small children suffering even tough its easily avoidable then the current energy production is just fine, its enough for rich people to be comfortable, for middle class who can affoard it to pay for it and for poor people to barely exist and die without affecting the systems functioning.
That's one of the main benefits of oil, its easy to seal, to distribute to hoard and decide who gets to enjoy its benefits and who doesnt.

On the other hand if you want to live in a political system in which your goal is to prevent small children to constantly experience suffering that borders on torture then collectively building green energy is the only logical path to go

I was gonna say something like this, but rather:

>See hydropower and geothermal take up so little footprint that it's hard for politicians to show knuckledragging normies what an outstanding impact they have in terms of energy effeciency. For you see, the average normie thinks that using water/drilling into the planet for whatever reason=bad. To counteract this we'll use the old tried and true method of windmill, for even a dumb peasant knows how those work. The more of them we make, the more we can show these stupid normies that we're at least attempting to care about their unjustified concerns over energy. Plus they're prone to far more failures which will mean more repairs=more make work jobs for our government employees/contractors. And because they're dumb, peasant, windmill technology, the stupid normie will already understand the pitfalls of it and it will be easy to sell to them.
>Also; nice, big, inefficient, outsourced and "green technology" solar panels. Gotta have lots of those. Put them everywhere and subsidize them! Even in places where you only get sun 3 months a years. Pawn them off to similar mindsets as your own; those that want to show they care but don't want to understand what they're caring about! They'll eat them up like hotcakes and be the talking point of their rich, suburban, neighboorhoods. "Look at those there, Tim.1500 sq. feet of solar panels all ready to power my wife's hairdryer at peak solar hours.

Oregon is powered by Hydro and has more life than any nuclear/coal powered state in the country. Dammed water make rivers wider and supports more wildelife. The cost is fish too retarded to use a fishladder.

The important measurement isn't "more life". If the only environmental concern ever was the number of organisms, environmentalists would be importing invasive species everywhere (but only the smaller ones so we can have more per acre).

>The cost is fish too retarded to use a fishladder.
Do some research on how ineffective they are. It's not really a solution in general.

Well maybe environmentalists have some sort of egotistical psychosis I'm not aware of, but last time I checked "more life" is better than "less life".

>Do some research on how ineffective they are. It's not really a solution in general.

You don't have a clue about what you're talking about. They power Oregon/Washington and as a result, those states have the cheapest electric bills in the country. Also any brainlet can understand that water flows downhill and a turning wheel generates motion. Also, what is a toxic byproduct of flowing water? Is it CO2? Nuclear waste? Constantly exploding gearboxes? Lithium/silicon strip mines? Hydroelectric dams and the structuring of water flow could power the entire US, but instead we have to hold ourselves back for animals that are either too dumb to live or are going to go extinct anyway. Would have been nice for the other smarter animals too, but guess they have to suffer now too.
By the way, this is the reason why California has "water emergencies". They are literally too stupid to store their water and instead impose laws on capturing water from river deltas because of the poor fishy-wishies.

it depends on location, but it's not a big deal
you usually build smaller forebays to trap sediment and debris

>>10102384
is about right, mayor reconstruction usually happens after 60-100 years.
dam crest will be renewed, leaks will be sealed new turbines might be installed. This will cost a few millions, usually less even then yearly profits.
Some dams here in my area are over 400 years old and still in mint condition. with regular maintenance they can do their job forever.
These dams serve more purposes then just power generation. Flood protection, fishing, recreation and most important as a source of drinking water.
