Renewable Sources of EnergyThe Impact of Oil on Southeastern Saskatchewan |
Part 1: Alternate Sources of Power
Part 2: Our Tour of the Fast Trucking Windmill
Part 3: Our Examination of a Hybrid Vehicle (gas / electric)
Our grade 5 class investigated ways of reducing pollution and
the dependence on Non-Renewable energy sources. We found that in Saskatchewan
we are using solar power, hydropower, geothermal energy and wind generated electricity
to save our Non-Renewable resources. An excellent website for all our topics
is found at:

Hydro Power
Hydropower is energy from running water. Usually the water spins the turbine that is connected to an electrical generator. The generator produces electricity for homes and businesses.

1. Which way does the propeller turn?
It can only turn counterclockwise.
2. How does it make power?
The wind turns a propeller that is hooked to a generator.
3. How tall is the tower?
26 meters
4. Why does it have to be that tall?
There is more wind at that height.
5. How long is each propeller blade?
Each blade is 7 meters long.
6. At what wind speed range will it run?
Between 8km/h and 80km/h
7. What is the electricity used for?
It is sold to Sask. Power.
8. How heavy is it?
The generator unit weighs 3600 kg.
9. Where are wind generators made?
They are made in Denmark.
10. What do you do for electricity when the wind isn't
blowing?
Buy electricity from Sask. Power.
11. How is it set up (built)?
It was set up using picker trucks and cranes.
12. What is the tower made of?
It is a galvanized steel tower.
13. Do birds ever run into it?
No, the noise keeps them away.
14. How much electricity can it generate?
The small generator makes 15Kw. And the large generator makes 65Kw.
15. What is the nacelle?
The generator cover.
16. What happens when it gets cold?
If it drops -20c the generator stops because the steel tower can break.
17. How much is one Kw. of electricity?
It will light ten 100 watt light bulbs.

Thank you Tony and Vi Day! We really appreciated the tour of the shop and windmill. It was very informative and helped with our project. It was a fun day. The Grade Five Class. |
As part of our study on alternative sources of energy we had a chance to
see
Dr. Prescott's hybrid car. We asked him several questions about his car which
we have listed. He even took us for a ride.
1.How long does it take to recharge the batteries:
(a) If you plug it in?
It doesn't recharge by plugging it in.
(b) If you are driving down the highway?
The batteries are constantly being charged by the motor.
2. How long will it run on batteries?
Just a few miles.
3. Where are the batteries?
In the trunk.
4. How many batteries are in the car?
2 batteries.
5. What kind of car is it?
Toyota.
6. What is a car worth like yours?
Over $30 000.00
7.What is an electric and gas motor car called?
Hybrid.
8.Are you the only person in Carnduff who has a hybrid
car?
Yes
9. When do you use the electric motor?
When you need extra power to acclerate.
10. When do you use the gas motor?
All the time.
11. How strong is the electric motor?
It is 300 volts, D.C.
12. How many miles per gallon?
60 miles per gallon.
