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.

Human beings are prideful creatures, and we have good reason to be. We have subdued a planet, changed the course of rivers, watered deserts, written poetry to make angels cry, and wrapped the world in a network of electric impulses and digital displays. We have created and killed not one but many gods. We can make a cloud rain by shooting heavy metal into it, and we can create a lake by pouring concrete in a canyon and damming a river. Most days, it seems that we human beings have everything under control and that if we miss wild nature, well, we can grow it in our gardens. (We can even genetically engineer the plants and animals.) Every so often, however, the universe spins out of our control. Forest fires rage. The earth quakes. Chaos descends like a great modern Zeus hurling thunderbolts and reminding us that nature is not ours to manipulate. In a great universe shaped by raw power and force, human beings are only small, easily crushed, organic structures. We need the reminder. Chaos and destruction are nature’s great gift to human kind because the realization of our frailty and insignificance leads to enlightenment. We learn something about ourselves, how we are here, where we want to go, and what we have to say about it.
Electricity is a vital thing in a day of the life of an American. Technological advancements have been able to help create new ways of producing the energy needed for that electricity. These new ways of producing energy are cheaper, safer, and have a better impact on the environment than fossil fuel based energy production. Of the new styles of creating energy, wind power has made its impact in the Midwest and has reached its way into Indiana. The use of wind power has proved it’s worth and will be a better investment for Indiana and the surrounding states because it is a renewable resource that pays for itself.
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.
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.
“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.
Wind energy has been utilized for hundreds of years. Such a simple technology and source of energy has always been around, and has been used slightly, but never to its full potential. Only recently have people been discovering and engineering ways to utilize the great, natural, free source of energy that the universe gives us. Renewable, safer, more efficient, and environmentally friendly sources of energy are becoming more and more important in such an, already, physically damaged world that we live in. It is becoming a household debate, and a debate in which many world leaders are taking notice and action towards. There is plenty of upside in investing in renewable energy, but people and countries are so reluctant because of how cheap non-renewable
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.
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
One of the biggest reasons renewable energy has not been widely used is the large start-up cost. According to research done by Jerry Taylor, power produced by wind turbines and biomass, which is burning or converting plants into usable energy, could cost up to twice as much as gas or coal powered plants. He goes on to say...
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.
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 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
Wind is a form of solar energy. The term wind energy describes the process by which the wind is used to generate electricity or mechanical power. Wind turbines convert mechanical energy from the wind into electrical power. Wind turbines usually have three main parts. There are blades that connect to a central hub, a box behind the blades that contains the generator, and a long stem that connects to the ground. The way how it works is that the wind turns the blades, which spins a shaft that connects to a generator making electricity. After the electricity is produced it is sent through transmission lines to a substation that is sent to business and homes. For the sake of our planet, we must promote a renewable energy economy. Wind power can be a foundation of that sustainable energy future because it provides jobs in states that are building wind turbines, is a renewable energy source, and does not damage our environment. The environment will not be damaged by the pollution, the natural resources will not be used up, and there won’t be generating of hazardous wastes. Welcoming wind energy today will lay the foundation for a healthy tomorrow that will affect everyone in the United States. There are obstacles and challenges that will make it more difficult, but the environmental impact is well worth it to invest more money into wind energy.
