...Wind Power as an Alternative Energy Source Although fossil fuels drive our economy, it is rather expensive and significantly contributes to pollution (Lad 2). A few alternatives include hydroelectricity, solar energy, and wind. Solar and hydroelectric energy are good choices, but can be relatively costly (“Top 5 Misconceptions of Solar Energy” 5), (“Hydro Electricity”). Wind, on the other hand, is free and available in most areas. However, wind power has not been fully utilized in the United States. The purpose of this paper is to give an overview of wind power in order to bring to light its usefulness as an alternative energy solution. Uses Wind power can be used to generate electricity, charge batteries, grind grain, etc. (Deshmukh 3). Turbines can be used alone or on a wind farm and can also be connected to a utility power grid to sell electricity back to the power company. According to the literature, wind technologies are most useful in the Midwest and along the coast. Pros and Cons Although wind turbines can kill birds and be damaged in severe storms (Deshmukh 11), wind turbines can provide many advantages. For example, wind turbines can harness the power of the wind, producing electricity, charging batteries, etc. Unlike fossil fuels, wind power consumes no fuel, and emits no air pollution. In addition, wind can be accessible in nearly all areas. Types There are several types of wind turbines, each having its own set of advantages and disadvantages...

...What is Alternative Energy? Alternative energy can be defined as any source of energy used to interchange fuel resources without harming the environment or energy derived from other sources without the use of natural resources: burning fossil fuels such as carbon dioxide which contributes to global warming. There are several types of alternative energy such as: wind power (focus of this report), solar power, geothermal energy, hydroelectric energy, alcohol and many more available for use. What is Wind Power? Wind power, a reliable source of electricity, can be defined as producing energy from the wind. Wind power is simply converting wind energy into a usable form of energy. Wind power is actually a form of solar power as wind comes from the sun. When air moves, generating wind, it has a kinetic energy: the energy created when mass in motion. The wind’s kinetic energy can be caught and transformed to other customs of energy such as electricity or mechanical power which are examples of wind power. Some examples that utilize wind power to some extent are: wind turbines which are used to make electricity, wind mills, a form mostly used, are used for mechanical power or wind pumps for pumping water. Wind was one of the earliest forms of energy harnessed to do work, one of which is sails which propel ships. Wind is an entirely renewable resource hence the reason why it is considered a pure and clean form of energy. They are different types of wind mills available for...

...study Wind is the most economical and safest means of energy generation. Wind can supply energy without emitting harmful substances and chemical compounds that contribute to the rampant acceleration of the destruction of our environment that lead to global warming. Furthermore, wind power is the best option other than any other means of electricity generations such as fossil fuels and other harmful energy resources which cause damage not only danger to the human health but as well as to the environment. The multiplication of the usage of wind energy as a power source for electricity is worldly outgrowing. An estimation of 45,000 megawatts were installed in 2012 and ten percent increase in installation was recorded, a large difference if we compare the data gathered in 2011 and in 2012. The unbalanced heating of the atmosphere due to the sun’s energy results to the formation of winds, the untypical surface and the rotation of the earth around the sun causes winds. Wind directions are interrupted by the mountainous structure of the earth, its hydrologic state and its land plains. When winds pass turbines, it can generate electricity. From kinetic energy, wind propellers changes it into mechanical energy, this mechanical...

...Prof Layton 3/24/13 Essay#1-Explanatory Alternative Energy What is Alternative Energy? It’s an energy generated, in ways that do not deplete natural resources or harm the environment. There are about four types of natural alternative energy. Each energy has a different element used to create energy. The types of energy are wind power, solar power, geothermal power, hydroelectric power, and nuclear energy. In the next paragraphs, I’m going to explain the reasons why the world needs alternative energy and how the energy is harnessed. First type of alternative energy is wind power. Using large blades can capture the winds power. The wind causes the blade to rotate turning into electrical current. Electric generators harness all the energy and distribute it to small towns or larger scale towns. There are some advantages for using wind power. First, it causes no pollution. Meaning there are no harmful by-products. Keeping the world safe. Second, wind power is a renewable source; we will never run out of wind. Third, wind turbines can be placed practically anywhere. All you need is a good source of wind. As with any energy source, there are always some concerns. One concern is that wind is never constant. Some days there is significant amount of wind. Then the next day no wind at all. Another concern is that residents that live next to turbine blades think they are ugly. Second type of alternative energy is solar power. This is created by capturing the sun’s rays into solar...

...Alternative Energy Sources Geology Many people believe that we must depend on fossil fuels for energy, where as the reality of it is the earth provides an abundance of renewable energy sources. These energy sources can produce enough energy that we would never have to use fossil fuels again. Alternative energy is the use of other energy sources instead of the use of fossil fuels or nuclear energy. Solar power can be used to operate cars and provide electricity to homes and businesses. Hydropower can be used to provide electric power to small towns and cities. Geothermal power can heat up buildings or water to power turbines to make energy. Wind power can be used to pump water and generate electricity. So let’s start with solar power since it is the most known of the group. Energy from the sun is one of the most abundant resources available today out of the alternative group. It is one of the most important of the non-conventional energy sources as well, because it does not pollute the earth. “One of the reasons for this is that the total energy we receive each year from the sun is around 35,000 times the total energy used by man”. (Alternative Energy Sources) One way to capture the sun’s energy is through the use of solar panels made out of Photovoltaic cells, which are commonly called (PV) cells. These panels can be used on homes, businesses, greenhouses, water heaters, traffic lights, or grouped together as a solar power plant. PV cells can transform the sun’s energy directly...

Type the abstract of the document here. The abstract is typically a short summary of the contents of the document.] Abstract This paper will review solar and wind energy as the alternative energy sources to replace fossil fuels and nuclear energy. Solar and wind energy has experienced phenomenal growth in recent years due to both technological improvements resulting in cost reductions and government policies supportive of renewable energy development and utilization. Fossils fuels and nuclear energy have been the world’s main source of energy for years but, with global warming and with a recent melt down at a Japanese nuclear plant many are questioning is it time to use other alternatives energy sources. Although both alternative energy sources are safer than fossil fuels and nuclear energy the world has been reluctant to switch power sources. The recent severe energy crisis has forced the world to develop new and alternative methods of power generation, which could not be adopted so far due to various reasons. Solar energy represents our largest source of renewable energy supply. The Sun is naturally Earth’s most abundant energy source and will be around for billions of years. This is a resource that essentially human beings won’t be worried about running out of anytime soon. Wind Energy, like solar...

...Abstract Years to come, coal will not always be the main source of energy. It will soon run out and other ways to produce energy will be needed. There are different ways to produce this type of energy, such as solar power, wind power, and hydroelectric power. If corrected and created now, then ways to get energy other than coal in the far future will be one less thing to worry about. Alternative Source of Energy Source of Energy A big discussion today is what humans can turn to now and in the future for energy. Everyone knows that coal will not last forever and in the meantime it is crucial to find an alternative to produce the amount of energy the world needs to survive. The faster our nation starts on alternative sources of energy and understands that fossil fuel hurts the nation and makes the country weaker, the better chance our nation will have in the time to come. There are different ideas of how to produce this energy such as solar power, wind power, and hydroelectric power. Solar power is the energy used from the sun and is turned into thermal and electrical power (Winteringham, 1992). It is a very reliable source that can be used to produce energy. The sun has been around for a very long time and it is a source of energy that people can rely on in many places around the world. There are many advantages to solar energy. The main motive for most people is that solar power is free. Unlike coal, supplies for it are unlimited to use. Solar is efficient...

...Renewable Energy Solutions for the State of Arkansas Energy, currently we have renewable and non-renewable energy sources available to us. Examples of renewable energies are solar and wind. Non-renewable energy sources are nuclear, coal, oil and natural gas. As most homes and businesses are currently using non-renewable energy sources, we need an energy solution. How can we protect our earth for future generations? We need to use energy more efficiently and only use what we need. We need a sound energy solution that is efficient and conservational, we need a renewable energy source. For the State of Arkansas, what is the most effective renewable energy source, solar or wind? The way of the future is through renewable energy sources. Two such sources are solar energy and wind energy. These sources are un-limitless in mastering its power. Solar cell panels that transfer the sun energy into power with no pollutants can use solar energy. Harnessing the wind via windmills or turbines for energy production uses wind power. Now that we know about the two different renewable energy sources, let us look at each source and what the positive and negative impacts would be and determine what would be an effective energy source for Arkansas. Some of the positives are the fact that solar power is renewable and has an un-limited supply; there is enough solar energy that falls in a 100-square-mile area of the southwest United States to power the entire nation.

...Alternative Energy With the world economy growing at a fast pace, energy demand too has been witnessing a sharp rise in the past few decades, with demand mainly originating from the big developing economies of Asia, namely, India and China. Factors such as high population growth, growing urbanisation and changing lifestyles in these developing nations are behind the increase in demand for energy. According to International Energy Agency (IEA) estimates, during 1990-2008, while world population increased by around 27%, energy use increased by around 39%. Consequently, average per person consumption of energy has seen a rise of 10% for the same period. The year 2010 has seen a further increase of around 5% in the world energy consumption levels. Most of the countries in the world use coal, oil and natural gas as their primary sources of energy. Around 90% of the total global energy requirement is met through these non-renewable energy sources. This heavy reliance on fossil fuels poses certain major concerns. Most importantly, these sources are limited. So, it is only a matter of time before these resources are exhausted completely. Another important factor that works against the heavy use of fossil fuels is that they are detrimental to the environment. The use of fossil fuels leads to emission of greenhouse gases which causes global warming. Also, these fuels are a major source of air, water and soil pollution. All these factors have created a need for alternative energy sources...

...Winds of Change Sonya Marquis BUS440-801 Introduction Wind energy is a renewable resource, which means that future supply will not be affected by current use. The rising concerns about global warming, pollution, and depletion of natural resources makes wind a viable and logical source of energy for the near and distant future. There are many advantages to wind energy; it is a sustainable energy source that is non-polluting. With a 30 percent annual increase, wind is the world’s fastest-growing bulk power electricity source. Montana has a bright future in wind energy. The American Wind Energy Association ranked Montana’s wind-energy potential in the top five in the nation. Currently, the state has several utility-scale wind farms in operation. History of Wind Energy Wind energy has been used by civilizations throughout time. As early as 5000 B.C., wind energy propelled boats up and down rivers. Simple windmills pumped water in China in 200 B.C. Wind energy technology and its applications continued to grow and diversify throughout the ages. By the late 19th century, settlers of the New World were using windmills to pump water, and eventually, to generate electricity. Small windmills were used until the late 1920s to bring electricity to rural Americans. Farm and ranch communities in Montana used wind generators that produced direct current (DC) electricity that was often stored in batteries. However, these systems were short-lived due to the Rural Electrification...
