SOURCE ADVANTAGES DISADVANTAGES
 

HYDROELECTRICITY
Produce inexpensive electricity Disrupt natural river flow
Reservoirs used for flood control, irrigation, drinking water, and recreation Slow down river flow that can kill fish and other animals that depend on a steady flow
Renewable energy source Alter water quality
Increases reliability of energy sources Significant obstacle to fish and other animals
Improves air we breath Can impede the natural flow of sediments
Fights climate change Expensive to build
Small hydro plants using local rivers can be practical for some communities Flooding large areas of land
Disruption or destruction of habitats
Displacement of Aboriginal and other communities

 

SOURCE ADVANTAGES DISADVANTAGES
 

 

 

         WIND

Energy production does not produce greenhouse gases Old designs emit noise
Does not contribute to global warming Some people do not like the visual impact created
Farming and grazing can continue on land where wind turbine is located Wind does not always blow or remain constant
Renewable resource Barriers to bird movement
Inexhaustible Cause fatal bird collisions
Produces fuel source that can never be depleted
No air pollution
No water needed
No need to tear up the ground or destroy habitats
Small environmental footprint
New designs emit minimal noise
One wind turbine can supply a large area with energy
