1. Hydroelectric Energy
Madison, Meghan, Emmet

2. Pros of Hydroelectric Energy
Hydro energy is free and no money is needed to buy the water from rivers in order to use it to produce energy
When a dam is built, you can expect an abundant production of electricity, especially in areas where the river has a large water reserve
Dams are meant to last for a very long time.
Building a dam ensures electricity production to last for years

3. Hydro energy contributes to the storage of drinking water
Hydroelectric power plant reservoirs collect rainwater which can be used for consumption or for irrigation
Hydro energy production doesn’t release greenhouse gases into the atmosphere
It is a clean form of energy
Hydroelectricity prevents the emission of greenhouse gases equivalent to the burning of 4.4 million barrels of petroleum per day worldwide

4. One advantage with a dam is that if electricity is not needed, you could just halt the production of electricity and save the water in the reservoir
It is renewable
Whenever the water is used to produce electricity, it would be replenished by rainfall. This cycle is continuous .

5. Cons of Hydroelectric Energy
Droughts
During drought or dry seasons, the water levels in the reservoir may decrease
Slow down electricity production
Cost
Expensive to build power plants
Dams must be built with precision, accuracy and with the right materials
Expensive to buy proper materials and workers with the right training
Environmental
Interventions in nature like damming of water, changed water flow and the construction of roads and power lines
Damaging effects on fish species

6. Cons of Hydroelectric Energy
Limited Reservoirs
Large power plants obstruct roads
Not enough reservoirs for hydroelectric power plants
Will not produce enough energy for amount of people supporting

7. How it Works?
Electricity is generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water.
This flowing water spins a turbine which then creates power within a generator that is then fed into the power grid.

8. Where Does it Come From? Dams: Pump Storage:
Pump Storage utilizes off peak hours to pump water from lower reservoirs to elevated retention basins which then send water down during high usage hours.
Conventional hydroelectric is created through large damns and reservoirs.
