Hydropower is one of the oldest forms of electricity generation, having been used since the 19th century. It’s also one of the most controversial, thanks to its effect on ecosystems and local communities. Hydropower involves using dams to trap water in order to generate electricity through turbines connected to generators. In many cases, this can be done without creating enormous lakes—instead, hydropower systems use reservoirs behind dams or simply use existing bodies of water like lakes or rivers.

Hydropower is not renewable

Hydropower is not renewable.

This might seem like a strange thing to say, but it’s true: the water that goes into generating hydroelectricity cannot be used again. It’s gone forever, and we can’t get it back. The reason why this matters is because there’s only so much water in the world–and we need all of it for other purposes too!

Hydropower is unpredictable

The biggest problem with hydropower is that it’s unpredictable. Hydropower is dependent on the weather and climate, which means it can be affected by drought or flood. Hydroelectric dams generate electricity when water passes through turbines, but if there isn’t enough water in the reservoir behind the dam (or if too much water flows over) then there won’t be enough power produced for your home or business to use.

Dams cause negative environmental effects

Dams can cause negative environmental effects, such as:

They are not 100% efficient. A large amount of the available water is lost through evaporation and seepage. This means that dams aren’t a good way to store water for dry periods, when you need it most.
Dams can cause flooding and landslides downstream from them as they hold back water that would otherwise flow downstream naturally (and with little force). This problem is especially relevant in areas where there are steep slopes or unstable rock formations along riversides–the kind of places where dams tend to be built!
Dams change the flow patterns of rivers by slowing down their current speeds, which causes erosion along riverbanks downstream from dams throughout their lifetime; over time this leads to changes in local habitats such as wetlands being destroyed completely or becoming polluted with sedimentation from faster flows further upstream

Dams can cause habitat loss and displacement of species

Dams can cause habitat loss and displacement of species. When a dam is built, a large area of land is flooded by the reservoir. This can destroy habitats and ecosystems, as well as prevent the migration of species that rely on certain conditions (such as water temperature or flow rate).

In addition to flooding areas with no immediate need for electricity production or irrigation, dams also displace people who live in those areas–sometimes against their will. The construction of hydroelectric power plants has led to forced relocation of indigenous peoples in countries like Brazil, Peru and Ecuador without their consent or compensation for lost property rights over traditional lands

The biggest problem with hydropower is that it’s not really sustainable or renewable.

Hydropower is not renewable, and it’s also unpredictable.

A dam creates a reservoir, which is basically just a big hole in the ground that can fill with water when it rains or snow melts. When you build a dam, you’re only blocking part of the river flow–there will still be some water flowing out of your reservoir even when it’s full. But if there isn’t enough rain or snowmelt to fill up your reservoir every year (or even every few years), then you’ll have wasted all that money building something that doesn’t work very well! You might need multiple dams to make sure there’s always some water coming through them–but then again, maybe not enough people will want electricity from those dams either way?
Also: what happens if someone builds another dam upstream from yours? Now there’s even less water coming through for everyone downstream! And since hydropower plants are usually built near big cities (where people have money), this means poorer areas may get left out altogether…

We’ve talked about the problems with hydropower, but what can be done to make it better? There are many ways to address these issues. One way is by using renewable energy sources like wind and solar power instead of hydroelectricity. Another option is to use dams that don’t cause as much environmental damage by using less water or building them in areas where there isn’t any wildlife or plants living nearby.
