Many people today are spending quantities of money for the electric bill without knowing that their hurting their wallet and their environment. It harms the environment because the fuel you receive in your electric bill is called traditional, which is made of fossil fuels. These fossil fuels create pollution in the air affecting our ozone layer. A solution for this problem would be to leave the traditional fuel and enter to the new world of alternative energy.
My alternative energy is wind energy which is caused by wind turbines or windmills. The windmill has been used for many years in history. Windmills, according to AE Wind Turbines, are used to generate electricity from the kinetic power of the wind. According to Trufts Now, depending on the speed of the windmill, it affects the production of electricity from the windmill. The article claims that if a windmill rotates slowly, then it produces less power, but if the wind speed doubles, then the windmill will produce eight times more power than in normal conditions. The windmills contain two main two main kind of wind generators, the vertical and horizontal axis.
There are three main fossil fuels in the world: coal, natural gas, and oil. These fossil fuels helped create one of the oldest traditional fuel named Hydroelectric Power. According to USGS, in 2006 the US had about 7% of total power produced by hydroelectric plants. A hydroelectric power is used to turn a turbine, which then turns a metal shaft in an electric generator, which it produces energy. A hydroelectric plant uses falling water to turn a turbine. The hydroelectric theory is to build a dam on a large river that has a large drop in elevation in which it stores lots of water behind it reservoir. The shaft of turbine goes up into the generator, which produces the power. Hydroelectric plants are more efficient at providing for peak power demands during short periods, and a way of doing this is by using “pumped storage”, which reuses the same water more than once. This traditional fuel may not use as much of fossil fuels, but it does release many greenhouse gases.
As for many things, the windmill has its advantages and disadvantages in producing energy. If you have a windmill an advantage would be that the wind is free, so no worry expenses, and with modern technology it can be captured efficiently. But the disadvantage would be that the strength of the wind is not constant and your electricity would vary, which means that the windmills do not produce the same amount of electricity all the time.
These include the history of windmills and their role concerning the survival in the immense plains that range from east of the Rocky Mountains to the Mississippi River. The rise of the economic condition of those living around the wind farms along with the surge of investments from energy companies. Finally, the promising data relating to the amount of energy produced, and the consequences they will have on the environment. In the later and longer part of the article, the possible negative results or wind farms are brought up. Primarily, the points against wind farms have to do with the conservation of wildlife. This is separated into two sections, the first addresses the dangers wind turbines present to birds, the other on the dangers presented to bats.
The purpose of this lab is to see how many blades on a windmill will create the most voltage. Another purpose of this lab is to find out at what blade angle will the windmill create the most voltage. Wind energy has been used for thousands of years because it is a renewable source; therefore, the wind power will never run out. WInd energy had been put into use by 5000 BC ,and simple windmills in China were used for pumping water, and vertical-axis windmills were grinding grain in the Middle East. The new technology of wind energy was taken to the New World in the 19th century for pumping usage and to generate electricity for homes and
Overall wind energy is a renewable energy resource that is natural occurring with unlimited supply. Wind energy has very little adverse effects on the environment. As technologies increase, the cost of wind energy will continue to decrease. There are many advantages and disadvantages to wind power. In the near future, hopefully the many disadvantages will become obsolete and wind energy will become more popular.
Many people support the idea of alternative energy, yet there is no move to implement it as a viable alternative to fossil fuels. It is the burning process that makes fossil fuels so bad for the environment. An alternative source that does not require combustion is necessary to avert the process of global warming. Wind power and hydroelectric power both turn t...
Wind energy is a current source for alternative energy. Current applications of wind energy are giant wind turbines that are placed in the country on wide open farm lands. Also Great Britain and Denmark have had off shore wind turbines since the nineteen nineties (Galbrith), this shows that wind energy not only has potential but is already proving successful. However wind energy has a long way to go before we can expect to power our world off of it. Research is being conducted to trim the costs of wind power and quadruple the amount of energy output. According to Mr. Fredette of American Superconductor, turbines are going to double in size to six megawatts (Galbrith). Which means that one turbine will soon be able to do as much work as two accomplish today. A company in Virginia conducted a study on wind power and found that if they got started on a project to make two hundred tall wind turbines that in two years they could be making twenty percent of the state’s electricity (Walker). This study shows that a significant amount of electricity could be produced from wind turbines, which in turn could go along way towards saving our planet and lowering green house gas emissions. Another positive point about wind energy is the abundance of jobs that are brought up with it. Research in Kan...
Windmills are incredible creations that have its importance in our history. Early pioneers utilized windmills for pumping water out of the ground and provide the water for their cattle's over a century. Throughout the years, diverse outlines and varieties were made to make the windmill run more effectively. In spite of the fact that there have been many plans made, a large portion of the windmill parts still remained unaltered.
One of the main types of renewable energy that we have used the most is the wind energy. Wind energy is the energy produced from the power of the wind. Throughout the 20th century, wind energy was used by sailboats as a fuel to move the boat in different directions. In the past, this was the most frequent way for shipment of goods. Sailboats were also used as a method of transportation. Also, wind energy is used to power wind turbines and convert the wind energy into electricity. Without the wind energy, the production of electricity and the shipment of goods would have been very difficult and perhaps life on earth might have perished. Thus, the efficient ways of using the renewable energy such as wind energy has played an enormous role to our existence and it has made engineers more successful at harnessing
A lot of cultures have taken advantage of wind energy for hundreds of decades. It was used when sails were incorporated to navigate the River Nile in 5000BC and Persians used -windmills in 500AD so that they could pump water and grind grain. Now-a-days, wind energy is being realized as one of the “most promising new energy sources” and is going to be an important alternative in years to come.
Non renewable energy, such as fossil fuel, is used all over the world. Big part of the population assumes that fossil fuel is a reliable source of energy, easy to obtain, and is relatively cheap. On the other hand, fossil fuel is a non renewable energy, which means that we can use it only once. Also, this burning fossils are not good for the environment and are the main reason of the global warming. In this era a lot of new technologies have been invented. Although not every created invention has been for good, renewable sources such as, solar, wind, and human power are a good alternative of energy. Despite some people thinking that solar energy isn’t helpful and it’s only a bad investment; solar energy is the best way to reduce the greenhouse gases and decelerate the global warming, also, is a good investment and it will help you save money in a short term, and unlike the burning fossil fuel, is not harmful for human’s health.
Each one of us has their own opinion about what wind turbines do and not what they are actually meant for. Wind turbines are meant to be an energy saving method that can be used ...
Wind vitality is a spotless fuel source. Wind vitality doesn't dirty the air like power plants that depend on ignition of non-renewable energy sources, for example, coal or flammable gas. Wind turbines don't deliver climatic discharges that expansion medical issues like asthma or make corrosive rain or nursery gasses
The Wind Turbine is a device that converts the kinetic energy of the wind into kinetic energy of turbines. The turbines turn to generate electricity but they work only when there is wind. The efficiency is 30-40%. The environmental impacts are needs many large turbines to generate electricity which can be noisy and unsightly. Turbines may endanger birds and bats.
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.
The wind is an incredibly valuable renewable energy source and is in the forefront of renewable energy developments. It is used to convert wind energy into energy that can be harnessed and used via a variety of methods, including; wind turbines, windmills, sails and windpumps. For a renewable energy source, however, it is wind turbines that are used to generate electricity (see figure 1). Wind power has been used for this since the end of the nineteenth century, after Professor James Blyth of the Royal College of Science and Technology first attempted it (Boyle, 2012). However, It wasn’t until the 1980s that using wind power technology was sufficient enough to experience a rapid growth of the technology.
For years man has relied on energy in order to be successful in life. The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than ever before. Now, with new, innovative technology there is an opportunity to change that and to rely on renewable, cleaner sources of energy. The main source of energy for the world should be alternative energy instead of energy from fossil fuels.
