Everyday we sit and work with our laptop, watch TV, play with tablets, use the coffee machine, use the lights, etc. Electrical appliances and devices exist today in very large numbers and will keep on growing at a very fast rate. In order to meet demands for electrical power, fossil fuels have been the main force of producing electricity ever since the industrial age. As effective as fossil fuel is, it will not last forever due to the fast rate of consumption and increasing electricity demand. As supplies of fossil fuel dwindle, it has become clear that renewable energy will become the primary source of global energy. Of all renewable energy sources that are available, wind energy stands at the top. We had use wind to do work for us centuries ago, it used to power windmill that can pump water or grind grains. Today, wind energy is used to generate electricity harvested by wind turbines. Many people are skeptical that wind energy would not provide enough energy for the global grid, or worry about the environmental damage caused by implementing this technology. However, thorough research can counteract those skepticisms. Further development of this technology would also increase the potential of it being a major source of electricity. It is one of the most attractive renewable energy, because it is subject to many different types of design that helps it to work more efficiently, it can become cost efficient in the near future, and it has the potential to meet the global energy consumption needs. Renewable energy has been somewhat a puzzle for me since childhood. At home, I would always turn on the TV use the light, and much more. At that time I did not care where the electricity came from because it was so accessible that I did not ... ... middle of paper ... ... Integration: A Case Study of Oman."

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
It is well known that nowadays wind power is one of the fast developing energy sources of the world. Thats why one of the GE’s Energy business maintain a strong focus on building the wind power facility and delivering the technology in its fields and benefiting the advantages of wind power. GE has over 12,000 wind turbine operating in all around world with the countries like USA, Canada, China and Spain.

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.
Energy is the basic necessity of daily life. Nowadays, dependence on fossil fuels for energy needs becoming lower in numerous countries due to the potential of renewable energy to supply sustainable energy to the huge populations in many developing countries who are short of clean and continues energy. Generally, renewable energy can be defined as energy that is derived from natural resources which are constantly replenished and theoretically inexhaustible. Fossil fuels on the other hand can be described as energy that cannot be renewed and will eventually diminish. Thus, in many developing countries renewable energy is the alternative energy to replace non-renewable energy or commonly known as fossil fuels. In addition, according to Sorensen (2004), there is a greater demand for renewable energy sources nowadays due to the uncertainty of fuel price rise in living expenses. Commonly, there are many types of renewable energy available in our world such as wind power, biomass energy, solar energy, hydroelectric power and geothermal energy. However, the main three example of renewable energy are hydroelectric power, solar and biomass energy (Refer to Figure 1 in Appendix 1).
In the debate of traditional energy vs. renewable energy the clear winner is renewable energy. Renewable energy is vastly superior over traditional energy because it decreases dependence on foreign resources, produces no emissions, and is not limited in quantity. Opponents of renewable energy are likely to argue that this is not the case and that instead, traditional energy is better because it creates job growth, is reliable during all hours and climates, and comes with a lower cost. These advantages however are either misconstrued or hardly outweigh the long-term positive benefits of renewable energy.
When picking an energy resource for the topic of this paper, I bounced around a lot of ideas. Then it occurred to me that I should write about what I will be living with in about a month. My mom just finished designing and building our earthbag, solar, off-grid house, a four-year endeavor. I will soon live in a place powered by one of the most common alternative energy resources, solar energy, so I should learn more about it. At our new house, we have two stand alone pedestals with six 170W panels on each pedestal, making for a 2040W or 2kW solar system.
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 resource.
The United States currently relies heavily on coal, oil, and natural gas for its energy. While the price of natural gas per barrel continues to plummet, the United States is constantly seeking new sources of renewable energy. Renewable energy consists of any type of natural resource (solar power, ocean power, wind power, rain, snow, etc.). that naturally and automatically replenishes itself. Renewable energy is important because it is infinite and everlasting, meaning our children and our children’s children will be able to utilize these resources long after we are gone.
Offshore wind turbines have been a topic of discussion for a while now and people just simply can’t agree. There are the supporters and there are the problem makers as well as advantages and disadvantages to this idea.
Why do we need to rely on renewable sources? Most of the energy that we use today comes from fossil fuels such as natural gas, coal, and oil. All of these resources are non-renewable, so you can finish one day. In order to have a better world and a healthy environment for the future, people are trying to obtain energy from natural resources instead of non-renewable sources. In the lecture “Renewable energy resources” (2014), Mistry focuses on some advantages and disadvantages of renewable energy.
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.
