For many years now, it has been debated which of the new and upcoming renewable and sustainable energy sources if the best to use. Energy create from wind, is a very favourable contented in this debate as it is a very good alternative energy source. Wind energy is used all around the world. Humanity has been using wind energy for over 100 years. For example, we used to (some still do) use the wind energy to grind grain in old fashioned wind mills.. Nowadays, we usually use the newer term called “wind turbine”.1 About four percent of the energy created in the United States comes from wind energy,2 and over 100 countries are now following in this trend and produce energy through the use of wind. This not only shows that a wind energy has great potential in the future, but also how popular it already is. It can be said that the more countries there are that using wind energy the better it is for our world. It is better because wind energy is a sustainable energy source.3
Looking back already at around 1000 AD wind power used and spread around northern Europe, starting with Holland. In 1850 the first company was created which started building wind mills because of the already then

What happens is that since the air on the land takes less time to heat up than the air on the ocean, the warm air on the land starts to rise and expand. As the warm air rises the cold air flows into its place as, hence creating a flow of air, which is wind. During the night the opposite happens. The air on the land cools down faster than the air on the water, the same process occurs and wind is again created, meaning that a wind turbine can be used day and night. The only necessary condition for wind turbines to work is that there is wind, which turns the blades. However, the even more important conditions is the energy from the sun as solar energy is what heats up the air during the
The Thorp Mill was one of many locally supported gristmills that were built in the last years of the nineteenth century. Spanning along the waterways of Washington State, these mills ran off of the power supplied by diverted water currents. In Kittitas County alone, there were competing mills especially closer to the larger populations in nearby Ellensburg. This did not prevent the success of the local mill production of Thorp. Not only did the Thorp Mill outlast many of the other gristmills of the region, it became a center of the local community, producing not only flour, but electricity and a place for the local population to connect.
The novel, The Boy Who Harnessed The Wind, by William Kamkwamba and Bryan Mealer, beautifully illustrates that humans must continually adapt and repurpose in order to survive. The theme of adaptation is most evident in the windmill that William created. William got the idea to build a windmill from a picture he saw on the cover of the textbook, Using Energy. But William did not have the specific materials, money or resources to build it.
Wave energy converts the motion of waves into energy. According to Boem, there are many different designs that can be near the shore, float on the water, or under the water. Almost all of them use pumps or turbines to generate power. Some offshore designs have waves enter into a chamber, and when water splashes around in the chamber, air is pushed into a hole, which has a turbine in it. The air spins the
In the story The Boy Who Harnessed The Wind a young boy named William Kamkwamba wants to help his family by doing things that interest him. William is very determined and his curiosity is the driving factor behind him and what he does. When most people doubted him he showed them that he could do anything that he wanted. William was determined to not become a farmer like his father and wanted to do something in a science field after he found a book called Explaining Physics. When he found that book he realized he could help his family in ways they couldn’t imagine.
Factory Conditions In the North By the mid 1800’s More and more things were made by machines. Clothes, shoes, Watches. These machines had to have operators.
“The man who has everything figured out is a fool...it takes a smart fella to say, ‘I don’t know the answer’ ” (Lawrence and Lee 55). This quote was stated by Henry Drummond, a protagonist in the play Inherit the Wind, written by Jerome Lawrence and Robert E. Lee. The quote is ironic because Drummond is stating that although it is important to know the truth behind something, it is just as important to know when an individual is wrong. In the play, one learns how the surface of things never truly reveals how they really are.
Through my AP English 12 class I had to read and write an essay on Jerome Lawrence Inherit The Wind. For this essay the students had to choose a passage from the play and explain its significance to the work overall, for some reason the passage at the top of the page called to me. As I wrote this essay I realized how much my view on the world has transformed from just a year ago. In the past I blindly relied on my faith and believed that whatever happened to me was out of my control, however, I have realized I hold the reigns to my life. I realized that all of my choices determine my future, for bad or for worse, I believe this to be true.
Women in the Mills of Lowell, Massachusetts In 1810, Francis Cabot Lowell returned from England. He brought with him plans for the first power loom textile factory in the U.S. He built the factory beside a waterfall on the Merrimack River. He did this so he could use waterpower to operate large looms to weave cloth.
. When a force is transferred by a moving solid object to another solid object, the second object will generally move in either the same direction or in a direction at a small angle (less than 90 degree) to the direction of motion of the first object, unless subjected to another force. However, the method by which forces are transferred from a fluid to a solid object is very different. Wind turbines are operating in an unconstrained fluid, in this case air.
The romans used the wind for various reasons such as transportation and water pumping. The wind power would be used to power sailboats down the water and allowing the Romans to move goods or travel around to other countries. “The economics of long distance water-borne carriage for bulky and heavy goods compared with overland carriage were recognized long ago. Historical records indicate that some 1,200 large merchant vessels reached the port of Ostia every year (about five per navigable day).” (Newman, “Energy in ancient times”)
Electric cars or internal combustion engine cars; which one is better? Electric cars were in their prime back in the early 1900’s, but a sudden rise in petrol engine cars, alongside with battery technology issues killed electric cars by 1920. However, with new improvements in battery technology and power electronics, electric cars have resurfaced. I will compare these different technologies, and come to understand which one is better.
Air conditioning air conditioning means for maintaining the specific conditions of temperature, humidity (moisture in the air) and the level of dust inside a closed space. The conditions that remain are dictated by the need for the conditioned space is intended. History of Air Conditioning A brief account of the progress in the field of refrigeration and air conditioning stands as understanding Ancient Egypt - Ancient Egyptians are loosely credited as being the first to use evaporative cooling by hanging damp cloth or reeds in windows and doors. As the wind blew through the wet materials, home air cooled.
The Boy Who Harnessed The Wind The Boy Who Harnessed The Wind is a biography and an autobiography written by William Kamkwamba and Bryan Mealer. The story takes place in Malawi, Africa in the late 1900’s and the early 2000’s. This book is about William Kamkwamba and everything he has gone through. William and his family have gone through starvation, and sickness, and poverty.
Renewable Energy in the United States By 2014, Renewable energy in the United States reached to the 13.2 percent of the local generated electricity, and 11.2 percent of total generated energy in the United States. All of these types of renewable energy sources are produced, but in variant amounts. Also, the policy of renewable resources are varies from state to another. California is a leading state in this field. Approximately 20 percent of California's electricity power comes from renewable sources, this percentage far higher than the US average.
Technology is also fast under development which harnesses the energy of the sea. United States alone has a potential of 2100 terawatt - hour of energy from waves incident on its shores. While the technology is still nascent, development is underway to create commercially viable solutions which use the energy of ocean waves & currents and convert this into electricity using specially designed generators. Considering that the world is 75 per cent water the potential for ocean-wave related energy is huge. A number of technologies harness solar power.
