Wind Power: Nature’s Gift
Wind power is a clean and renewable energy that, while at times unreliable, has very low upkeep cost and is growing at a rapid rate. While there is currently enough wind power to provide many times our current energy need, it is unfeasible in reality. Wind power utilizes the kinetic energy of air and uses it to power a generator to produce electricity. Even though dependence on wind power is impossible, it still can provide a strong, clean, quantity of power to supplement current energy production.
Wind energy is essentially the conversion of the kinetic energy from air molecules in motion to mechanical energy which is generally then converted into electrical energy. People have used wind power since 700 AD in

Wind power and solar power also tend to compliment each other; a study by the Massachusetts Maritime Academy has shown that generally, while wind speeds are high solar power generation tends to be low and vice versa, so the two could be used in conjunct to make up for each other’s weaknesses.
The main cost of wind energy is in the initial investment in the construction of a wind turbine; the upkeep cost is generally marginal and lower than one cent per kWhr. In general, wind power works by having air molecules move across the turbine blades transferring kinetic energy from the molecules to the turbine, causing it to turn. As it turns, the mechanical energy can be used to perform tasks such as grinding grain. More commonly, the turbine turns and utilizes a power generator to convert the mechanical energy to electrical energy.
While wind power is currently more expensive per unit of energy (the initial cost of construction is spread across a turbine’s lifetime, generally around 20-30 years) than alternatives such as coal; wind power lacks the negative externalities that other energy sources produce, namely pollution, through the formation of CO2, heat, and other waste materials. Once factors such as health problems, global warming, destruction of wilderness and such come into play, wind energy becomes a very
Wind is a form of solar energy so when it is used it creates electricity. Electricity is a physical phenomenon associated with fixed or moving electrons and protons. The wind power development was a step forward for the use of electricity on how to generate more electricity using the wind. The accomplishments for electricity is that Senegal used 10MW for a wind farm and they gave a positive report and is now using it since the second half of 2005. (Dodge) Another thing is during the Second World War; small wind generators were used on German U-boats to recharge submarine batteries as a fuel-conserving measure. The good thing about wind power is can produce electricity at night as well as during the day and that it is plentiful, renewable, and it reduces the greenhouse gas emissions. (ERIC) The Wind Power would be cheaper to develop electricity and it is less harm to our daily lives.
Unlike its sister energy supply, fossil fuels, wind power is a clean resource. Wind turbines don’t pollute the air like power plants, which rely on the burning of coal or natural gas. They’re free from producing atmospheric emissions that cause acid rain or greenhouse gases.
wind power to produce enough energy for the citizens. Other sources of energy being used
Wind Power is power obtained by harnessing the energy of the wind. Uneven rays, temperature, and the rotation of the earth are what cause wind, warm and cold, which in turn provides energy. Wind turbines are the main items used to provide energy from the wind. Wind turbines have large blades that turn in a circular motion at the top of the tower. As the blades turns, it causes a shaft to turn as well inside the tower. The shaft is connected to a generator which generates electricity. These wind turbines are placed on either onshore or offshore wind farms. Onshore wind farms are placed on ridges, hills, and seashores, since those are the best areas to catch wind. On the other hand, offshore wind farms are not only very difficult to build and maintain, but on the bright side, pick up more wind than onshore wind farms since they are placed in the sea (Fridell pp. 13-18). This source of energy is good to use since it is very efficient because the wind usually occurs around the world. Wind energy also provides jobs. Wind jobs are growing 12 times faster than other industries. And, a wind turbine technician is the fastest growing profession in the United States (Samuelson 2017). Also, just one wind turbine can provide energy for several houses. For example, In the book, Earth Friendly Energy on page 34, It states, “In 2005 the total was 58,982 megawatts. On the average, one megawatt of wind power can serve 160 U.S
Wind energy is a clean, alternative source of energy that does not produce greenhouse gas emissions and can be produced domestically. While wind energy accounts for a small overall portion of the energy produced in the United States, the potential for wind energy is significant. Nevertheless, there are some obstacles that delay the widespread use of this technology, including intermittency of wind, cost, and public policies that deter their implementation.
“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
Wind energy is a form of solar energy. It is a process using wind to generate electricity. We are powering wind turbines that can easily transfer it to something useful. Pros: 1. Renewable 2. Abundant 3. Good Availability Cons: 1. Expensive 2. Associated with Pollution 3. Requires Space
We are facing an energy crisis on Earth. Burning fossil fuels are harming the atmosphere; this global warming and affects produces chemicals that hurt our body. People are starting to think about using alternative energy. Wind power would be our first choice, because it’s clean, inexhaustible and renewable. Today, wind power is mainly used in Europe. We believed wind power would be the main source of alternative energy for world use.
First, wind energy should be used in America, because other energy such as coal, gas, and oil can run out. It also is not the cleanest way to make energy. Wind energy on the other hand is a reusable clean resource that will last forever. Wind energy is one of the least expensive sources of energy. It is also safer for the
We use wind turbine so we can use the wind's energy to generate electricity. At 100 feet aboveground, they can take advantage of the faster and less turbulent wind. Farmers and ranchers in windy areas can also use wind turbines as a way to cut their electric bills. Small wind systems also have potential as distributed energy
Fossil fuels are having great impacts toward nature such as global warming and greenhouse effect. Plus, the depletion of it contributes to the rising price of petroleum. Therefore, wind power rise as it is a source of clean, non-polluting renewable energy (Nash, 2008). This type of energy generation provides us with loads of benefits environmentally and economically.
Wind Turbines and wind energy have been proven to be helpful, in the fact that it is a renewable resource. There is always a downside to something good, even with something that seems perfect. There are a few downsides to wind turbines themselves, some being environmental problems. I expected
Wind Energy is a viable industry that has become a valuable energy source. The energy generated from wind is clean and efficient. The wind energy industry helps to ensure that electric demands are met, wildlife impact is minimal, the environment is not devastated, as well as creates new jobs during the construction of wind farms, daily operations, manufacturing components, and exporting components to foreign countries.
Wind energy is generated by changing wind currents into alternative types of energy using wind turbines. Winds are generated by complicated mechanisms involving the rotation of the temperature gradients between
We have harnessed wind for thousands of years for transportation, agriculture, and for power. Thus, wind energy has been one of the most recent developments in the field of renewable energy in the last several years. Wind farms seem to be essential in our society to the continued push to reduce fossil fuel usage and greenhouse gas emissions. A cheaper form of energy that also emits less pollution than traditional forms of energy production sounds perfect. We would never know about the issues with it though, as far as most people know, wind turbines are helping produce productive energy through the wind. If people are not familiar with the dangers that very productive systems bring, then one might as well watch the TV, but mute the sound. It is great to focus on the big picture of projects, but take a look around and see what the big picture could be affecting.
