Pros of Hydroelectric EnergyHydro 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

Hydro energy contributes to the storage of drinking waterHydroelectric power plant reservoirs collect

rainwater which can be used for consumption or for irrigation

Hydro energy production doesn’t release greenhouse gases into the atmosphereIt is a clean form of energyHydroelectricity prevents the emission of

greenhouse gases equivalent to the burning of 4.4 million barrels of petroleum per day worldwide

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 renewableWhenever the water is used to produce electricity,

it would be replenished by rainfall. This cycle is continuous .

Cons of Hydroelectric EnergyDroughts

During drought or dry seasons, the water levels in the reservoir may decrease Slow down electricity production

CostExpensive to build power plantsDams must be built with precision, accuracy and

with the right materials Expensive to buy proper materials and workers with the

right trainingEnvironmental

Interventions in nature like damming of water, changed water flow and the construction of roads and power lines Damaging effects on fish species

Cons of Hydroelectric EnergyLimited Reservoirs

Large power plants obstruct roadsNot enough reservoirs for hydroelectric power

plants Will not produce enough energy for amount of

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.

Where Does it Come From?Dams: Conventional hydroelectric

is created through large damns and reservoirs.

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.
