Sources of Energy By Andre, Howie, Austin, Asina, and Krizia
Energy Source • Our energy source is Wind Power.
What is Wind Power • Power made by the movement of wind.
How it Works • This is how wind power works. • First the wind blows on to a blade which makes it spin. • When the blades spin it turns on a generator • The generator creates energy. • The generator works like a battery that connects to different machines like lights then comes back to the generator in a circle. • The faster and stronger the wind, the more power. • http://www.youtube.com/watch?v=eXejxcW-XGo
Where it is Used • Farms: For different farm machines. • Open fields of different towns and cities: For different things you use in different places. • Homes: For things you use in your house like lights . • Schools: For many school supplies like electric sharpeners. • Famous places where its used: Spirit Lake, Iowa, Wisconsin, and Minnesota.
How Much it Costs • For high powered wind turbines (windmills), it usually costs up to 2.6 million dollars. • Some cost even up to 3.5 million dollars • There are also companies who sell them for 3,000 dollars, 5,000 dollars, 35,000 dollars, or 45,000 dollars.
Environmental and Health Concerns about this Source • Flying animals, such as birds, can crash into the spinning blades • People complain about the noise they produce on windy nights • It could overpower because the blades spin to fast which make things die out.
Reliability • Wind Power can be very reliable • Wind power can create 48 billion kilowatt-hours. • It doesn’t run in oil, but instead it runs on everlasting wind that can’t be wasted. • Wind power can be used from up to 14 miles away.
How Much of Canada’s Energy Come From it • Canada’s electricity was 2.3% wind power (5,265 megawatts) by the end of 2011. • We say that we can produce 55,000 megawatts (20% of Canada’s electricity) by the end of 2025
How Much More Can We Use From it • Canada says that we can use up to 55,000 megawatts(20% of Canada’s energy) by 2025 or more.
Advantages From This Source • You do not need to buy wind and can be captured easily. • At most times it does not cause any type of pollution • You do not need to work hard to find wind • There are a few wind turbines that don’t take many space
Disadvantages of this Source • Sometimes the wind can be too low, which means you are stuck with low or no energy at all • The wind can be too strong and overpower your devices • They could be very noisy • If you are unlucky it can cause pollution • Some people think it is a scary or unpleasant sight
Facts • The speed of the wind determines the amount of power being used. • The blades on a wind turbine are curved so it the wind could push it down for it to turn. • People have to turn stop their wind turbines during a wind storm so that their electrical items don’t overpower, so really you are left with no energy. • Wind turbines can be used to determine the amount of wind outside (weather.) • Wind can also be used to sail a boat along the seas, but you can only go the direction of the wind. • The first time wind was used was as early as 5000 BC to sail across many seas
1 More Fact • The largest wind turbine recorded was used in WWII, on Vermont Hilltop in the 1940’s which was called Grandpa’s Knob. It recorded 1.25 megawatts on days where wind travels 30 mph.
End • This is the end of our science presentation about wind
