The Energy Industry in Canada
Introduction to Canada Canada is the second largest country by total area (9.9 million km²), but is one of the smallest by population (35.31 million). The gross domestic product in Canada is $2.153 trillion (CA$), and the GNI (gross national income) per capita is $61,517.7 (CA$). The top source of energy in Canada is hydroelectric (63.7%), nuclear (15.0%) followed by solid fuels (13.1% coal, but is a shrinking industry in Canada as it was eliminated by Ontario in 2014). Solar, wind and tidal energy also make up a small portion of Canada’s energy source.
Hydroelectric Energy Hydroelectric energy is the main energy source in Canada. 63.7% of the energy generated in Canada is hydroelectric. It is a clean source of energy, and is quite efficient. This form of energy is generated commonly in Quebec, where it produces almost all of the electricity distributed to people in Quebec. Hydro-energy is a clean, renewable and efficient source of energy as it generates electricity from flowing water, but leaves impacts on the environment, both negative and positive. Dams can block fish migration, disturb fish habitats, change water flow rates, and cause erosion on riverbeds. Hydroelectric energy leads to significant environmental changes. Dams also lead to other benefits such as

The plan could create over 50,000 jobs, and is estimated that it would save 17 megatons of greenhouse gas emissions every year. Some people (16% who took a survey) are opposed to this method of energy because they believe it will lower property values, and some say they are loud, and some simply don’t want a huge white spinning machine in their back yard. However, many wind farms have become tourist
The article “Hydropower as a Renewable Energy Source” (n.d.) shows that man-made dams make up seventy-five percent of the United States’ total renewable energy.
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.
Jerry Rolsten of Mendon, Ohio believes in progress and wants the wind farms to continue going up (Thompson 2). There are many positive viewpoints to the newly developed wind farms. “Wind farms produce no air or water pollution because no fuel is burned. Coal is known to be the dirtiest of all fossil fuels and has been connected with acid rain, as well as air pollution caused by particulates” (Parks 61), but that’s not the only reason wind energy is better than fossil fuel energy. Americans will no longer have to be dependent on the foreign fossil fuels because wind turbines diversify our energy portfolio, and the US will no longer be funding other countries and terrorist groups in the midwest (Engdahl 69).
The major sources of energy in the US from highest percentage to lowest percentage are oil, coal, natural gas, nuclear fuels, renewable energy
The use of turbines from dams to provide power was a brilliant idea until water levels started running lower than normal. The water waste from humanity is directly contributing to portions of it, aside from drought conditions affected by pollution, widespread fires battled, and more adds to the depletion thereof. When humanity is relying on power provided from dams to handle the demand, they are essentially relying on the assumption that water levels will always be there to provide it. The Hoover Dam provides power to the southwestern portion of the USA that has a large number of people.
Hydro power is one of many examples of alternative energy source. Hydro power is producing energy by moving
The first type of renewable energy is hydroelectric energy or well known as hydropower. In greek word, hydro means water and thus hydroelectric energy refers to electricity generated using flowing water at high velocity. Lutgens and Tarbuck (1992, p. 163) stated that “running water is of great importance to people as we depend upon rivers for energy, travel and irrigation”. Continuous availability of water in universe made water to be the main source of hydroelectric energy. Water has been widely utilized by mankind since the beginning of civilization and wate...
Offshore wind turbines will provide more jobs, cut pollution, stop warming on our planet, and save us energy costs. These wind turbines can generate enough energy offshore to power about 500,000 homes. However, many people disagree with this idea because they believe it is too expensive. Offshore wind turbines have been a topic of discussion for a while now, and people just simply can’t agree. There are the supporters and there are the problem makers, as well as the advantages and disadvantages to this idea.
Hydropower, the use of water to power machinery or produce electricity, provides the most renewable energy in the United States, and uses alternating current in most modern plants ("Hydropower…”). Hydropower relies on the water cycle and is a clean fuel source; it doesn’t pollute the environment like plants that burn fossil fuels. It is by far the most efficient way to generate electricity, being half the cost of using nuclear power, two-fifths the cost of using fossil fuels, and a quarter the cost of using natural gas ("Wind and Water…”). Also, hydropower is not subject to market fluctuations of embargos, and the average lifespan of a facility is 100 years. Hydropower also has many non-energy benefits such as water supply, flood control, navigation, irrigation, and recreation. However, it does face many environmental challenges such as impacts to aquatic habitats, aesthetic alterations of landscapes, changes to water quality, and interruptions of marine life ("Hydropower…”).
One efficient way to acquire energy is Hydropower. Hydropower is power derived from the energy of falling water or fast running water. This energy converter is harmless to the environment. Other ways will affect the atmosphere and the environment in a negative way. The most common device for hydropower is a dam. It relies on the water cycle. This is one of the oldest sources of energy.
Although renewable energy can be expensive to build, it has less environmental damages in comparison to non-renewable energy. Besides the natural resources such as sun, wind, water and hydrogen, we also have geothermal power, and biofuels as renewable sources. First of all, solar energy is the energy produced when the sun heats the solar panel. Thus, when the sun heat the panels, it produces electricity. Solar power produces energy during the day and can storage energy for the night. Solar power does not pollute so much the environment. However, it has high maintenance cost, and it takes a large land space. Secondly, 15% of World electricity comes from wind. In order to have wind energy, it is important to have turbines to get the wind in order to produce electricity. Tall turbines produce more energy. The drawbacks of wind power are that it requires steady wind and its installations may interfere with TVs, cellphones, and other electrical devices. However, it is quickly built and there is no pollution nor noise produced. Third of all, the water falls in the dam can also generate electricity. For instance, 19% of world electricity comes from water. Regardless of the fact that hydroelectric power has low maintenance costs and does not pollute the environment, it can cause earthquakes, and destroy wild rivers. Only 0.3% of world energy
Hydroelectricity is a renewable source that can be used for years and cam be expanded in many different ways. It also can produce energy from running water without reducing its quantity and can be utilized with other renewable sources that promote energy. Hydroelectricity contributes to the storing of drinking water by collecting rain water, which can then be used for irrigation; however it can also improve the air you breathe because it doesn’t release any toxins or pollutants. For a century, hydroelectricity has made long term improvements environmentally and can continue to do so for many years to come because of how affordable this technology is. (Lamb)
Wind power is one of the most sustainable ways of generating electricity as no toxic emissions are produced; it does not add to global warming and is one of the most available sources of renewable energy and theoretically it is an infinite source of energy. On sufficiently windy areas, wind turbines are one of the most economical methods of generating electricity, which makes it appealing to many individuals, governments and organizations. Due to this it is the fastest growing source of electricity in the world (Union of Concerned Scientists, 2014) with a 10% increase in yearly additions installed in 2012 compared with 2011 (Global Wind Energy Council, 2012). However the proportion of energy that can be harnessed through wind power is restricted by the cost of the infrastructure needed, construction, the amount of wind that occurs and that there are only a narrow number of sites within the UK that are windy enough for the wind turbines to be worth installing.
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.
Hydroelectric Power Plant is when electricity is generated when water in an uphill reservoir flows downhill. The gravitational potential energy of the water changes to kinetic energy of the flowing water which drives the turbines to generate electricity. The efficiency is more than 90%.
