There are two types of resources for fuel and energy. These are nonrenewable and renewable resources. Nonrenewable are those that do not renew themselves at a sufficient rate for sustainable economic extraction in meaningful human timeframes. Renewable are those natural resources that can be replenished naturally with the passage of time. The key difference is that the nonrenewable cannot be replaced once they are used, while renewable resources can be.
Our traditional fuels are fossil fuels. These include oil, coal, gas, and several others. All of which are nonrenewable. The process to get energy from fossil fuels begins when they are dug up. Then they are transported to an enclosed environment. Here, the fossil fuels are heated to a point which the molecules become excited. They only work when combustion takes place. This causes the hydrocarbons present to create energy. Overall, the molecule produces large amounts of energy.
This energy, in the form of heat, is then converted in a boiler to mechanical energy. The mechanical energy is now superheated, high-pressure steam. The steam is directed to a turbine, which causes the blades to spin and ultimately spins the entire central shaft. The rotor powers the generator. The generators job is to convert mechanical current into electric current. Finally, the electricity flows from the power plant, to the power lines, into our individual homes. Although fossil fuels are very productive, they require energy to start of the combustion reaction. Also, as it has been stated before, they are nonrenewable.
On the other hand, there are wind turbines. These are a source of alternative energy. Wind turbines are also known as wind power plants. A large number of wind turbines are called a wind farm. The wind-powered electrical generators convert kinetic energy into electric current. Their energy is gathered from a renewable resource, wind. This process is founded on the rotation of the turbines’ propellers.
As the wind passes through, it causes the propellers to rotate.

- Many people today are spending quantities of money for the electric bill without knowing that their hurting their wallet and their environment. It harms the environment because the fuel you receive in your electric bill is called traditional, which is made of fossil fuels. These fossil fuels create pollution in the air affecting our ozone layer. A solution for this problem would be to leave the traditional fuel and enter to the new world of alternative energy. My alternative energy is wind energy which is caused by wind turbines or windmills.... [tags: clean power production, renewable resources]

- ... At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind. Turbines catch the wind's energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor. (renewableenergy.com) Wind power has become affordable enough to compete with fossil fuels. Around the world utility services are offering wind-generated electricity at a premium of 2 to 3 cents per kWh. A household that uses wind power for a quarter of its electrical needs, the cost would only be $4 or $5 dollars per month for it and the price is still dropping....

- ... In addition to this, initial estimates of how long wind turbines would offer up optimal energy production only placed this time frame at about ten years, thus it was believed that these would not be a good long-term choice as an alternative energy source. However, studies have found that this time frame should be more than doubled, as there are wind turbines that have been operating for almost twenty years, and are still producing three quarters of their initial output when new (Imperial College London, 2014)....

- “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....

- Alternative Source of Energy: Wind Energy Over the last couple of years, scientists have discovered the alarming environmental damages that result with the use of traditional fossil fuels. Not only are fossil fuels a threat to the environment, but they are also an expensive source of energy that is being used up very quickly with such high consumption rates. As a result, scientists are currently developing cheaper renewable sources that can be used as alternative sources of energy. Among the several alternative sources of energy that scientists have developed is wind energy.... [tags: Wind power, Renewable energy, Fossil fuel]

- When a person looks into a light coming from a movie projector, they will notice many types of dust particles being spotted by the brightness coming from the box. These same particles, if not worse particles, are also floating outside and can be carried a long distance away if blown properly. Many citizens are frightened of this aspect, thinking of all the different germs that float in the air which are being propelled by wind turbines. Germs do cause illness at times, but there are other health risks caused by windmills which must be noted.... [tags: Bombings, WInd Turbines, Power Plants]

The amount of power a wind turbine generates depends on the size and the wind speed. A larger turbine will generate and more power. This is due to the machinery and parts within it. A stronger and faster wind speed will also produce more energy. This is due to the blades of the turbine spinning more rapidly and creating more current. According to the Executive Office of Energy and Environmental Affairs, a 1 megawatt turbine on land can provide enough electricity to power 225 to 300 household, while a 1 megawatt turbine offshore can provide enough electricity to power more than 400 households. When the energy is stored in batteries, it is later used to run the wind turbine when there is no wind to rotate the propellers.
According to the U.S. Energy Information Administration, the average annual electricity consumption for a U.S. resident utility was 11,280 kilowatt-hours (kWh). On average, a power plant causes the price to be $0.141/kWh and a wind turbine causes the price to be $0.097. Therefore, the power plant puts the annual electric bill at $1,590 while the wind turbine put the electric bill at $1,094. An obvious difference is noticed.
When fossil fuels are compared to wind turbines, everyone looks at it at the wrong angle. They like how thing are and don’t want to change it. They see the price of the fossil fuels lower, because they are looking at it on the immediate effect. But when on the long run, a wind power plant is far more economic. Also, fossil fuels are nonrenewable, while wind power plants are a renewable source. Fossil fuels require initial energy in order to produce some, whereas wind is a constant resource. Another key point is that not everyone can own their own mine, but anyone can buy their own wind turbine. No matter how it is seen, the perfect alternative to our traditional fuel, fossil fuels, are the wind turbines. In my opinion, we all should definitely switch to wind turbines.
