Renewable resources are resources that have the ability to restock itself in some quantity (Field, 2008). Thus, the amount of the resource available to be processed, is determined by the restock rate (Field, 2008). Renewable energy is commonly categorized with renewable resources. Renewable energy such as wind is beginning to take hold in many parts of Canada such as Alberta and Ontario (Jones, 2013). However, in Ontario, wind power has been seen as more of a problem than a solution. One major problem with wind energy is its feasibility; capturing wind energy is, to some degree difficult to do. Wind energy is produced by the movement between two air masses, usually influenced by the radiation of solar energy by the earth’s surface (Freedman, 2010). It is very difficult to control the speed, direction and location of winds, thus, making the process highly unpredictable. This creates a problem with the demand-supply relationship. The greatest supply of wind energy occurs overnight when demand is low and dies down during the morning, when demand is high (Spears, 2013). This would commonly result in increase in prices to bring the supply-demand relationship to equilibrium, where the supply is sold at a reasonable price for both consumer and producers (Field, 2008). However, since 2006, Ontario has had a surplus of power, which has led to the government to pay neighboring provinces and states to take it (Canadian Press, 2013; Spears, 2013). In addition, the government has also paid private companies to stop producing power (Canadian Press, 2013; Spears, 2013). These problems have led Ontario to have a larger cost than the benefits from wind power.

With concern over global warming growing, people are starting to turn a more serious eye toward cleaner sources of energy. Instead of solar power making a comeback as the ideal form, we are seeing a growth in the use of wind power. Wind farms are beginning to crop up all around the country. This new trend has gathered significant attention. Questions are being raised concerning the effects wind farms may have, from critics and supporters alike. Michelle Nijhuis, in the article “Selling the Wind” discusses the arguments on behalf of and in opposition to the increasing use of wind power, addressing what the consequences may be on the United States.

“The most important environmental issue is one that is rarely mentioned, and that is the lack of a conservation ethic in our culture” – Gaylord Nelson. Energy has become an extremely hot topic over the last couple of years, with arguments for our energy worries ranging from environmental to political to economical or financial problems. The variety of energy sources available for Ontarians has been a positive outcome for citizens, but the consequences of using some of these sources has not been. The situation, although severely thought through, has been the root of inflamed quarrel among people. With approximately thirteen million citizens living in Ontario, the future of the environment and sustainable energy source is questioned. While there are many different types of energy sources that Ontarians can get their power from, the Premiere of Ontario should focus on renewable energy for the sake of future generations, the economy and the province. The majority if not all Ontarians utilized energy sources originate from; nuclear power plants, hydro power plants, and renewable energy sources.
According to Why Wind Works - Canadian Wind Energy Association (2017), "Canada wind energy is one of the quickest expanding major origins of new electricity". For example, in 2016, Canada’s wind generation grew by 702 MW spread among 21 new wind energy projects. Also in 2015, Canada installed capacity surpassed the 10,000 MW threshold, building the industry’s position as a mainstream source of cost-competitive and stable electricity
And now you’re thinking that it’s too expensive to build a wind farm let alone have your own wind turbine, but the prices of turbines have decreased over 80% since the 1980’s and it’s expected to keep decreasing⁴. The more people who turn to using wind turbines, the more the prices would drop. Supply and demand.
29 of some of the largest countries in the world source 90% of their energy from fossil fuels. It is time to stop the reliance on such resources because the outcomes of that are bas in in of itself. War, terror, violence, bad blood, constant drilling into the Earth, are all outcomes that we face because of how much we lean on these limited resources. The past few decades, the use of wind energy has been on the rise, but it is time to start relying on it and utilizing every way of attaining wind energy. Great ideas such as mini turbines to function streetlights to large turbines to function communities need to be used as much as possible for a cleaner and safer world to avoid a broad range of negative outcomes ranging from global warming to war and

Lastly, wind energy is cost effective in terms of the machinery used to provide it, as well as the cost of the energy produced. Although initially it was believed that the initial cost of wind turbine construction is too high to make it a cost effective alternative, long term studies have proven this to be inaccurate. Recently a study was conducted to determine the amount of time it would take for a new wind turbine, with an average lifecycle of about twenty years, to defray or offer net benefits greater than the impact it would cost to build them (Inderscience Publishers, 2014). It was determined from this study that the energy taken to produce wind turbines was offset after the turbines had been online and working for only five to eight months. This means that the turbines are able to run for an additional nineteen plus years without using further energy themselves, barring maintenance.
Wind energy or wind power is the extraction of kinetic energy from wind and the conversion of it into mechanical energy. Man has harnessed the power of the wind for many centuries. Wind is a type of solar energy. The sun heats the earth’s surface and the warmer air begins to rise. Cooler air flows into the area below the rising air causing wind. The Egyptians utilized the wind as early as 5000 B.C. by attaching sails to propel boats across the Nile River. For many years sailing ships on the open seas were powered by capturing the wind with sails. The Dutch adapted the windmill and used it to drain the lakes and the marshes of the Rhine River. Windmills are used in food production such as grinding grain. Since the early 1800s, windmills in the United States have been pumping water from the ground. The windmill was instrumental in the development of dry land farming in the Midwest after the Civil War. Hundreds of windmills are still pumping today to provide water for grazing cattle.
Too much wind will cause them to fail and they require immense amount of maintenance. Due to this, money will always be put into the same wind turbines in order to keep them functioning properly. The initial setup of wind energy bears an enormous cost and investment (Conserve Energy Future). We are still only in the initial stage of wind energy: less than five percent of the world’s energy comes from wind (National Geographic). The growth of wind energy is low, but if the production goes into a boom, then the plans for this energy will be undermined by the low production of electricity the turbines offer. The growth rate of an industry depends on the growth itself (Stanford University). This becomes a concern for wind energy, because the faster the wind industry grows, more energy will be required in building more turbines and more batteries. In this stage, the industry will begin to slow down. Not only is the production of this system expensive, wind turbines themselves average to about one-million dollars for installation. Not to mention, severe storms or extremely high winds may cause damage to wind turbines, especially if they are struck by lightning (Love to Know). This can ensure more money being pumped into turbines if they are damaged or completely destroyed by such weather. The initial expenses of wind-made energy will surely spike prices for electricity made from this source in order to pay off needed maintenance of these wind

Wind turbines are a great source of energy all around the world. Wind Turbines produce wind energy that can be used to power our homes. Wind turbines convert Kinetic energy into mechanical power. Then this mechanical power gets generated into electricity. Wind turbines make energy by the wind turning the large blades, which spin a shaft that is connected to the large blades, which then operates the generator making electricity. One new idea is building wind turbines offshore in the mid-Atlantic. Offshore building of wind turbines means that these large turbines will be placed in the Atlantic Ocean. The building of these wind turbines will provide energy to states like Maryland, Delaware, New York, Virginia, and New Jersey. These states want to start this project as soon as possible so that the states can start saving money. Since these regions right now are burning fossil fuels uncontrollably with incredible impacts (not only to our air, but to our health) it is crucial to start right away. Offshore wind turbines will provide more jobs, cut pollution, stop warming of our planet, and save us energy costs. These wind turbines can make enough energy offshore to power about 500,000 thousand homes. However, many people disagree with this idea because they believe it is too expensive.
Wind power is one of the greatest creations a man could come up with. Wind power is the
Wind power is beneficial in many ways it produces a clean form of energy that saves our valuable fossil fuels. Wind power is even healthier for us, because this type of alternative energy does not produce harmful chemicals into the air which can mix with rain that is a part of our water supply and it decreases the amount of acid rain we have, so we can breathe cleaner air and drink clean water. In the state of Missouri wind power that is used for electricity only cost the user of this energy about 6 or 7 cents. However the price isn’t this low in every state in the United States. “The energy used to build a wind farm is produced by that farm within four to six months. After that, the energy it produces is free.” (Oxlade) According to Tony Zamberlan the state of California and other places with a larger population have the price of 10 to 15 cents a KWH. “Wind is a fuel, and it’s free.” (Hosansky) In the United States alone wind power has created 85,00 jobs and 400 manufacturing plants. Wind power is one of the fastest growing manufacturing sectors. It is a large possibility that wind power could produce thirty percent of the world energy within the next fifteen years. The turbines don’t even have to be put on the land we need right now. Wind turbines can be build out at sea. Wind power is even made on demand. Many of this is debatable in some parts of the world. In parts of the world where it isn’t as windy as Chicago or some places in Missouri energy from wind power is more expensive than energy from fossil fuel power stations. According to David Hosansky in 2007 it was reported that wind power cost $23.37 per megawatt hour nuclear energy at this time was $1.59 coal was $.44 and natural gas was a quarter. This alternative energy is also not consistent, if the wind doesn’t blow the turbines can’t create energy making this an unreliable source of energy. Wind turbines are known as a mature technology yet they
