Investment Opportunities Counter Thesis Loss of Money
Unreliability Canada should stop using wind power as a source of energy because it puts many people out of work due to the health risks it may cause. Refutation of Counter-Thesis Economically, wind turbines can save a government money by reducing global warming. Also, wind energy creates jobs and are great investments. However, wind turbines can put farmers out of work due to illness. Many people support wind energy because it is very clean and one of the most environmentally friendly energy sources. While farmers argue that wind turbines put their health at risk. Wind power is created by wind turbines that convert kinetic energy into mechanical energy. This can produce enough electricity to supply up to 560 000 average households in Canada, without polluting the environment.
Wind energy has an annual growth of 60% since 1998.
There are about 25 major wind farms in Canada. Introduction Reduce Pollution -Canada is the country with the 7th largest C02 emissions with an output of 574 million metric tons.
-The power sector is the responsible for 40% of global CO2 emissions, making them the largest contributor to CO2 emissions.
-On the other hand, wind energy emits no emissions whatsoever.
-Within three to six months of operation, a wind farm offsets all the emissions put out during construction.
-One wind turbine can save up to 4, 000 tonnes of CO2 emissions annually, a total of million metric tonnes annually. - Noise Pollution - Wind turbines create a low-frequency noise that is said to sound like a small jet engine.
- This can decrease the value of property that is in close radius to wind farms.
- An average of 40 families in Ontario have moved due to wind turbine noise.
- 70% of people who live within a 5km radius of a wind farm agree that they have been negatively affected by the wind turbines.
- Families are living without proper sleep due to the noise and vibrations caused by wind. Health Risks - There are many health risks that farmers face because of wind turbines. These risks are headaches, nausea, and vertigo. This is known as "wind turbine syndrome".
- These are all caused by the noise that wind turbines put off.
- Canada is facing many lawsuits because farmers are fed up and they want things to go back to normal.
- This could cost Canada a lot of money, and economic activity. Unreliability - Wind turbines can only produce power when there is wind, which isn't all the time.
- Wind turbines only produce one fifth of their true capacity. They could produce five times as much if they ran 24/7.
- Should we be spending millions on wind farms when they aren't even efficient? Creates Jobs - In 2011, approximately 570 000 people around the world were employed by wind power. Ranging from manufacturing to development.
- It is expected that by 2030 1.7 million people will be employed by wind energy.
- In Canada alone, by 2018 there will be 2,300 full-time maintenance employees in wind energy. Also, 900 full-time manufacturing employees, and 800 employees in construction.
- There is a shortage of engineers and skilled workers in the wind business right now. Wind energy creates new innovative jobs that aren't already available.
- There are also up to 400 wind energy companies located in Canada, such as the Canadian Wind Energy Association. These companies offer up to 6000 permanent jobs.
- Wind energy creates a lot of local jobs, this helps strengthen a community and brings them a lot of economic benefit. An average of $165 million of annual revenues to a community. This includes increased property tax revenues (thousands per turbine annually), royalty payments to local landowners, and increased tourism. Supply Matches Demand - If we use wind power to it's full capacity, then we could have enough energy to run 20% of the countries total power usage.
- Wind turbines create the most energy when it's cold outside, and coincidentally Canadians use the most energy in the winter. Investment Opportunities - By 2020, the Government of Canada hopes that they will be generating 90 percent of it's electricity using environmentally friendly sources.
- Over the past 8 years, 126 foreign companies have chosen to establish their green projects in Canada.
- The global wind industry is a $1.8 trillion industry. By 2025 Canada will hopefully generate $79 billion in investments to the wind energy industry.
- It's important to invest in local communities and companies. All oil investments go directly out of the country, whereas wind energy investments get pumped back into the economy.
-Wind energy produces more jobs by each dollar invested Sources Questions?

- Since 1980 prices of wind turbines have decreased by 80%, whereas oil prices are very unstable and are constantly changing.
- New studies show that global warming will cost Canada up to 5 billion by 2020.
- The 2011 Canadian budget shows a $58 million dollar funding towards climate change.
- Potentially reduce demand for fossil fuels and lower the price of gas and stabilize electricity bills. WAGES:

- Although wind turbines do create a low-frequency noise, it cannot cause hearing impairment and isn't loud enough to disturb sleep.
- Over the past few years new technology has been found and wind turbines are constantly changing, and every time they are becoming less noisy.
- Coal mining kills 13,000 people a year, there is no evidence to prove that wind turbines have been the cause of death to anyone in Canada. - Farmers say that the noise created by wind turbines causes a condition called Wind Turbine Syndrome (WTS). However, none of the symptoms of WTS can be linked to wind turbines.
- In 2010, Ontario's Chief Medical Officer of Health wrote a report on wind turbines and their health risks. His report shows that there is no scientific evidence to link the noise to any health risks.
- All research done comes to the same conclusion, the noise is simply an annoyance, however does not cause actual harm. - No power plant is ever 100% reliable.
- Although the wind turbines aren't always in movement, they are connected to grids, therefore when the turbines aren't in motion the grid can provide stable output.
- Wind turbines are in operation 60-85% of the time. - When a wind farm is built within close radius to your house, studies show that it decreases the value of your house by 40%.
- Many people with wind farms in their backyard have been forced to leave work because of all the health problems they've been facing. Loss of Money Loss of Money - Although the value of your house drops when a wind farm is located in your backyard, landowners get paid very generous royalties.
- Also, there is no scientific evidence proving that wind turbines cause sickness, therefore you can't assume that people can't work because of them. In conclusion, Canada should definitely convert to wind power because this will reduce CO2 emissions therefore saving the government money. This will also cause the creation of thousands of new jobs, and billions of dollars in investments.
