HYDROELECTRICITY
By: Alyssa and Aleesya
"Hydro" means water, "Electricity" is the science dealing with electric charges and currents.

WHERE CAN IT BE FOUND?
- Rivers
- Oceans
- North Mountains
Hydroelectricity can be found on rivers because the water in the river flows a lot. It can also be found in oceans where tidal power is used to generate electricity. This source of energy works best in places like Scotland, Norway and Canada where there are lots of mountains and lots of rain.
HOW DOES IT WORK?
- Pipes
- Turbine
The water is stored in a dam until power is needed. Then, the doors of the dam are opened and the water rushes down through pipes turning turbines along the way. These turbines turn the power of the rushing water into electricity.
EFFECTS ON THE ENVIRONMENT
- Doesn't Pollute the Air
- Numerous Environmental Consequences
The good thing about hydropower is that it doesn’t pollute because the dam doesn’t need very hot things like what normal factories have because the only way they could get electricity is by the turbine and the water.
The bad thing about hydropower is that it can create numerous environmental consequences.
The bad thing about hydropower is that it can create numerous environmental consequences.
About 3% of energy production in Indonesia is from Hydroelectricity
Approximately 3% of energy production in Indonesia is from hydropower even though it is a very good supply and source to save energy while they use a lot of things that aren’t renewable like petroleum and lots of other fossil fuels.
PRO'S
- Renewable
- Create a LOT of electricity
Renewable because waters cannot be wasted.
It creates a whole lot of electricity because there is a lot of water in the whole world.
It creates a whole lot of electricity because there is a lot of water in the whole world.
CON'S
- Environmental consequences
- Expensive to Build
It makes a lot of environmental consequences like floods.
The dam is very expensive to build.
The dam is very expensive to build.

In conclusion, we think the amount of hydroelectricity used in Indonesia should be increased.
