Wind Turbines: Why has it caused so much controversy in Puerto Rico?
As the Law of Conservation states, energy can be neither created nor destroyed (The Secret Lives of Energy). That means that an energy source has to be use in order to generate the energy needed. It is common knowledge that the pollution caused by the use of fossil fuels over time is making society live in a contaminated world. In addition, the cost of the use of fossil fuels is increasing and becoming too expensive, forcing people to find alternate ways in which they can pay less for the use of energy. The use of fossil fuels over time has increased to a point where the remaining reservoirs have decreased by a large margin. On the other hand, renewable energy is having a boom in its use and demand because of various reasons. Even though renewable energy is so great for the environment, it has a major downside. According to the website Renewables Talk, Energy sources such as wind and sunlight are intermittent, meaning that they are not always present. Because of this, they have to be combined with other storage technologies, such as batteries, to work efficiently and provide power when the source is practically nonexistent at the moment (Haluzan).
Throughout the world, wind turbines are in high demand and are receiving support from society. Wind turbines use Aeolic Energy, which is the same as wind energy, to generate power. Wind Energy is the world’s cleanest source for the generation of electricity because it causes no pollution or greenhouse type gas emissions that may harm the environment (World Changing: A User’s Guide for the 21st Century, 174). Even though wind is intermittent, there will always be some amount of wind energy during the day. ...

... making the project longer than planned. In Bacardi, it was another story. The project was planned correctly and led to the support from the community. It was a pilot project for a eco-friendlier approach in the island. The support from Bacardi, Aspenall Energies, and government agencies led to the development of the project with no major obstacle.
Wind turbine projects are starting to have a boom in the world, since Renewable Energy is essential for the well-being of the planet. With the involvement of the community and good planning like in Bacardi, these projects can be done with no interruptions. The Santa Isabel wind farm can be taken as a model to what to improve on the next project to prevent any obstacles on the development of another project. Improvements can be made using the Bacardi project in order to have the smoothest process possible.
Why don’t we use more renewable energy sources? What role do they currently play? According to Energy Kids, in 2008 renewable resources only produced seven percent of the energy that we used. One reason we don’t use a lot of renewable energy
There is physics involved in these wind turbines as they change wind into mechanical energy and then into electricity. The energy produced depends on the volume of the air, the density, and the wind speed. The mass per unit time is the mass times the density times the wind speed or m = mass, p = density, A = area, and v = wind speed; m = pAV. Because the function of the wind turbine is to transform the wind’s kinetic energy into electricity the equation for kinetic energy is needed; KE = ½ mv2 or kinetic energy equals one half the mass times the velocity squared. Then, using substitution, the power in the wind depends on the density of the air, area swept out by rotors, and the cube of the velocity or ½ pAV3. Using Betz’ law the theoretical energy model for extracting 59% of the energy is power = 16/27(½ pAV3) .
Thirty-seven percent of the energy used in the United States comes from oil. Natural gas comes in at second, contributes twenty five percent of the energy. Coal gives us twenty one percent of our energy while the other seventeen percent comes from other energy sources. Those other resources include nuclear, wind, and mostly solar. Besides the environmental harm that some people think fracking has, it has the potential to produce more natural gas and oil. It also is a non-renewable resource and will take a very long time for it to come back because of the earth’s natural creation. Solar and wind power are renewable, but do not produce enough energy to run our country. All of the solar panels and wind mills we have on the earth right now could ...
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.
In 1986, the National Renewable Energy Laboratories developed a wind resource assessment for the U.S. Department of Energy. The assessment consisted of surface wind data and upper-air data. The results of this project help today’s developers determine the best location for a wind farm, as shown in the map below.
In this paper, I will write about the history and present use of wind power and the pros and cons of using wind power as an energy source in Vermont.
In everyday life, there are things that one needs to survive. And sustainability problems arise every day. One such problem is energy loss. The world is using up a lot of energy and new ideas need to be formed to help the rest of the world and the future of the generations that are to follow, to survive. With that the problem is that people use up energy and they do not use it efficiently. Therefore scientists are needed to find ways to deal with the sustainability problem that is arising. That is where wind turbines are used to generate this energy but the actual wind-turbines are very large, loud and they kill birds, thus new designs need to be found in order to help energy usage and to bring the size and structure of the wind turbines to a smaller scale to prevent injuries to nature and the species around it.
Wind turbines can be very useful in bringing energy into your home. They are especially useful when solar panels aren't working. They take the wind speed from oceans, lakes, dugouts, or rivers and turn it into energy. To use the wind turbines most efficiently you should set up a wind power system.
Just as long as wind continues to blow and the sun shines, then wind power can produce energy to send to many different areas. There aren’t many locations that have continuous wind. And because of that, the widespread development of wind power isn’t as great as it could be. Although there are more advantages than disadvantages when it comes to this energy source, the disadvantages should be taken just as seriously. Wind power can harm animals, there was a study that stated birds were coming in contact with turbines and dying.
First and foremost, unlike power plants that rely on combustion of fossil fuels, wind turbines do not produce atmospheric emissions. Strangely enough, wind is a form of solar energy. Winds are caused by the irregular heating of the atmosphere by the sun, the variations of the earth 's surface, and rotation of the earth. This wind flow, or kinetic energy, when "harvested" by modern wind turbines, can be used to generate electricity. There is an abundance of wind to meet our needs, “the potential of [the total] wind power [in the world] is… 20 times more than what the entire human population needs” (Maehlum). Currently, wind power is one of the lowest-priced renewable energy technologies available, costing between four and six cents per kilowatt-hour, depending upon the wind
Wind turbines are a great source of energy 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.
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.
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 or noise produced.
In chapter thirteen of our book, Environment by Raven and Berg, it shows us just how important renewable energy sources are. Currently the United States of America thrives on the use of fossil fuels and nuclear power. The main problems with these types of fuel are that they are both limited and can be extremely harmful to our environment. They cause global warming, air pollution, acid rain, and oil spills (Environment), and not only that, but in the grand scheme of things, these sources really aren’t even that cheap of a fuel source. There are many alternatives to these all but outdated fuel sources.
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.
