Positive and negative Impacts
Dams are ___________ to ________
What resource is stored and moved to generate power for pump storage?
Water
What Natural resource is used to make the turbine spin in run of the river
Water
What type of water is used?
Saltwater
What structure is built across a river or body of water to hold back water?
Hydro is the worlds __________ source of renewable energy
Largest
What does it reduce dependecny of?
Fossil fuels
what happens to the water when electricity is low
More water is moved through the valves
Why is run of the river more environmentally friendly then a dam?
less construction and animal habitat changes
Why cant tidal not provide the same amount of energy
Due to high tide and low tide.
What is a reservoir
A controlled body of water built by humans to pump amounts of water into turbines
What kind of natural resource is Water and hydro power
Renewable
What is something that Hydropower creates for Canadian citizens and what are 2 examples
Jobs: Engineers, construction workers, electricians and technicians
How man reservoir tanks do pump storage center have
what is two
Is this a renewable energy source?
Yes
How does Tidal energy generate power?
from waves crashing and the power of the currents spinning turbines.
What damage can a reservoir cause to the surrounding area.
Flooding and habitat change
How much of Canada is covered in water
9%
How does it harm the land?
Blocks fishing migration routes, change water temperatures, flooding of farmland and forests
Why is water pumped higher into the reserve
To fall and turn the turbines
what does run of the river add to an ecosystem or river
Pipes and drains
What oceans does Canada have access to? Name all 3
Arctic Ocean, Pacific Ocean and Atlantic Ocean
Who communities can dam construction disturb or relocate
Indigenous communities
What does water turn to create to make energy
Turbines and generators
How can It effect Indigenous communities? 2 examples
It can cause displacement of communities, destruction of traditional hunting and fishing areas, disrupts cultural practices
Why is it most renewable and in most demand
The water can consistently be reused
What's the difference between run of the river and reservoir
Reservoir is controllable and requires dams
Why is tidal more predictable then solar or wind energy?
Since their is always high tide and low tide making it easier to read when you will get the most power
Why is storage and impoundment good for when electricity is in high demand ?
Humans control how much energy is produced at a time
How much % Water does Canada hold and how much of that is fresh water
20% of worlds surface water and 7% renewable freshwater supply
