The world 's population has been increasing exponentially since the early 18th century. In the 20th century, the world 's population was approximately quadrupled as it jumped from 1.5 to 6.1 billion people. As the population increases, one of the main concerns for engineers will be to harness and manipulate the energy in a way that it can sustain the world. When the population was lower at the beginning of the 20th century, it was very easy to maneuver energy in a way that it could support everyone in the world. However, as the population started to escalate, it become more difficult to harness and manipulate the energy. Over the past couple of decades, engineers have been very successful at harnessing and manipulating the energy as they found Renewable energy is derived from natural resources such as wind, rain, sunlight, waves, and much more. Over the years, engineers have found various efficient ways to use and harness the renewable energy. One of the main advantages of this type of energy is the fact that it can be used for a long period of time without it being dispatched. Also, this type of energy is cleaner and much more beneficial to the environment since it results in a very little amount of greenhouse gas emission. Renewable energy is also cheaper and more affordable compared to any other sources of generated energy. Due to these advantages of the renewable energy, engineers have decided to find more efficient ways of using renewable energy. Over the past couple of decades, engineers have been successful at finding more efficient ways to harness and manipulate the renewable 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
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.
Solar power for instance is one of the most popular and easiest of all of the renewable energy sources to harness, especially for home and business uses. (Galbraith) For around the same ...
Wind energy can play a critical role in saving our planet from the negative effects of energy powered by fossil fuels. Wind turbines work effectively at reducing carbon dioxide emissions. For instance, a single utility scale wind turbine can prevent the emission of 5,000 tons of CO2 into the atmosphere a year by displacing the power generated by fossil fuels. Also, a single 750-kilowatt turbine can produce roughly 2 million kilowatt hours of electricity annually. Turbines of this nature are the ones now being used in power plants around the world (Wind Energy Weekly). One good example is California. Their wind power plants displace 4.5 billion pounds of CO2 each year with the 3 billion kilowatt hours of energy they produce. To put it into an environmental perspective, that is as much CO2 as could be absorbed by a forest covering 1100 square miles (Wind Energy Weekly). Although wind energy has little to no impact on the environment when it comes to air pollution or greenhouse gases, there are other environmental concerns surrounding this form of energy production. Some of the concerns about wind energy include visual impacts, birds and other living resources, lightning and noise (Wind Energy Development).
Due to the development of technology around the world, the need of energy is increasing every year. But, what would be the best way to produce energy without polluting the air, or depleting fossil fuels? Renewable energy would also be the best solution for this problem. Of the available sources of renewable energy, wind power shows much promise. Wind turbines have been used through many generations, and the technology continues to develop. Wind Energy provides a feasible energy alternative to traditional fossil fuels.
“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.
As per the law of conservation of energy, “Energy can neither be created, nor be destroyed, but it can only be converted from one form to another”. Most of the research now is about how to conserve the energy and how to utilize the energy in a better way. Research has also been into the development of reliable and robust systems to harness energy from non-conventional energy
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).
As the population continues to increase at an exponential rate, there will be more demand for energy, food, water, infrastructure and so on. Engineers are supposed to fulfill those demands to the barest minimum. In this 21st century, newer and better forms of technology are being discovered and will probably soon be more used than other non-renewable energy resources. Renewable energy which is the energy from natural resources like sun, wind, rain and so on are being adopted in the present day. This is because this form of energy is naturally replenished and so can pose less harm to the society. Therefore, mechanical engineers have a duty to design renewable energy tools that will foster4 the research and establishment of these alternative means of
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.
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.
One of the most compelling arguments for the use of renewable energy is how many forms exist of it. Nuclear power, solar power, wind power, tidal power, hydroelectric power, pumped storage, wave power, geothermal power, biomass, and biogas are the most widely known renewable energy sources (Darvill, 2013). This large selection of fuels supports the idea of renewable fuels one day powering the entire planet. All the sources of energy have different niches and benefits. Solar energy is extremely effective when providing energy for small establishments such as a house or small store, but hydrothermal power would be a more plausible solution for factories or large establishments....

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.
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 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.
