All day working, for what? In a couple years there will be an invention to do it in a couple of seconds. Every second someone’s imagination is working to make life easier. One of the most unappreciated inventions in technology is the windmill or wind turbine. You may wonder how the windmill has affected life as it is today or if it has even affected it. To answer this, you’ll have to look at the history of windmills.
Early sailors were the first ones conceptualize the windmill. They were able to imagine what wind power could do, but did not have the knowledge of resources to explain the logic or physics behind the windmill, they just had the concept. But nonetheless with time, the idea of wind power then evolved to form the windmill. “It is uncertain who came up with the idea, but its purpose is to function in everyday life. Remains of windmills have been found in Ancient Mesopotamia and Persia (Higgins, p.12).” Windmills have been used by the earliest of people. They used it to grind grain which in turn helped mass production of food to help the population growth. Before the invention of the windmill this job was done by hand, which consumed much a lot of time. Nowadays wind turbines are used to generate electricity.
The design of the windmill has also transformed. Earlier designs were called vertical axis. A vertical axis windmill is one that stands vertically with the panels rotating in a horizontal motion. Overtime, it changed to a horizontal axis windmill. A horizontal windmill stands up and the panels move in the direction of the wind. Overtime a horizontal axis windmill proved to be more efficient than vertical axis windmills.
The whole idea of the windmill is not something thought about in ever...

...ou also would have to reroute your house to accommodate the use of the wind turbine so it stops using the fossil fuels and uses the energy source.
I believe that if we don’t move toward limitless resource we will be trapped using oils and gases forever. "I'd put my money on sun and solar energy. What a source of power! I hope we don't have to wait till oil and coal run out before we tackle that," by Thomas Edison. The journey to renewable resource will be a long one, but will only happen if everyone works together for the effort.
Overall renewable resource isn’t going to happen without major change in this country. Renewable resource will be an improvement to the system that is used today. The movement to green energy is a something that has to be done in tiny steps. The long term goal will be a better for the entire global, because it will to a better ozone.
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
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.
A wind turbine is a device that converts kinetic energy from the wind into electrical power. Small wind turbines we discussed for domestic use have fewer requirements to properties, but more considerations of cost compared to large wind turbine.
Ever since recorded history, people had the ability to use wind as a source of energy. Wind power was been used to propel boats along rivers as early as 5000 B.C. At 200 B.C., China used windmills to pump water, while in Persia and the Middle East used vertical-axis windmills with woven reed sails were grinding grain. (history-wind-energy, energy.gov) Eventually, discoveries for wind energy became vast. Plethora of ideas developed. During the 11th century, the Middle Easterners used the windmills for food production. Which then allowed nomads, merchants, and crusaders to further bring back the idea back to Europe. The Dutch further improved the windmill by making it for draining lakes and marshes in rivers. Settlers took this advanced technology to the New World, and began using the windmills to pump water for farms and ranches and much more. Then eventually, to generate electricity, for homes and industries and soon to become, wind turbines.
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.
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.
“A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy”. (1) The inventor of the first electric wind turbine was Clevelander Charles Brush, who ran his entire Euclid Avenue mansion off of one for 20 years, which later made the cover of Scientific American in 1888. (2) Although the use of alternate energy didn't rise a great deal afterward, this event did open the eyes for many environmentalists. Wind power is only one of our several “energy source[s] whose ‘fuel’ is free and will never be exhausted” (3) with the pros and cons not completely weighed out as to whether it will be truly beneficial or not. The two main issues regarding wind turbines are the environmental effects that they have and the cost effectiveness of building them.
Our country is currently suffering energy-wise, we have been powering with inefficient sources for years now and the harm that it is doing to the country has started to become apparent. Renewable energy is the only way to stop, or at the very least set back the inevitable downfall of our ecosystem. I think that the next big breakthrough for renewable energy is implementing off-grid communities that use renewable sources as their main sources of power, so that we can potentially escape the energy rut that we got ourselves stuck in.
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 ...
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.
The earliest known uses of wind power date back to 3000 BC, when people used wind to sail ships. Approximately 4000 years later, windmills were used in Europe to grind tobacco, wheat, and other grains. Later, in the 1700's, windmills were then used to pump water. It was not until the 1900's that wind mills were used for generating electric power. In the United States, windmills were used prior to widespead electrical distribution.
A wind turbine is basically a very large inverse fan, where wind is the input and electricity is the output. Today there are hundreds of different wind turbine deigns, most of them range from around 40 – 80m in height; 50 – 85m in span and 850kW to 4.5MW in power. Most of these wind turbines have 3 blades and possess horizontal axis shafts.
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.
