Before you decide on wind turbine power as the most appropriate for you to have, you should take time and learn about the potential pros and cons of wind turbine power. For the pros of wind energy you will enjoy the following benefits:
Pros of wind turbine power
The wind energy does not cause pollution. This ensures that when it is harnessed it helps in avoiding pollution of the environment which is unlike other sources of energy that can use pollution.
The energy has more potential hence it can be utilized to satisfy the power needs of many people in the universe.
The wind energy originates from the sun which makes it renewable. Even if we try to utilize it to the fullest we will not exhaust it.
The turbines used to generate wind power are space efficient. A single turbine can be used to power over 600 homes.
The wind power utilization is very small in the world, about 2.5% but with advancement in technology there is a promise on the increase on its utilization. The rate of utilization of wind energy is growing at a rate of 25% per annum.
The cost of producing wind power is keeping on decreasing and the operation cost of the wind turbine power is very low.
The power from the wind ensures homeowners continued supply of power from the wind hence eliminating outages.
Cons of Wind Energy
The wind energy keep on fluctuating hence it cannot sustain a base load. It can only sustain the base load after it has been used alongside other sources of energy such as hydro and batteries.
The energy requires heavy initial investments for it to be applicable in different places.
The turbines used in wind energy harnessing can pose a threat to wild animals such as bats and birds.
Neighboring homes can complain about noise that is produced. The aesthetic look for the turbines can also be a concern to the people making use of the turbine to harness wind energy.
Wind power is a type of solar energy caused by the atmosphere’s uneven heating by the sun as well as the rotation of the earth and earth’s surface irregularities. The wind flow is changed by the land, water, and vegetative cover on earth, resulting in a motion energy or wind flow that can be harvested by wind turbines and generate electricity. The turbines turn in the wind and convert kinetic energy into mechanical power, which can then be converted into electricity. There are two types of wind turbines, horizontal and vertical axis. The majority used are horizontal axis turbines made of a blade or rotor, a drive train, and other equipment that help generate electricity from wind power.
Wind turbines are grouped together to make a wind farm to generate electricity as a bulk. The electricity is then fed into a utility grid. Turbines come in different sizes and power ratings, from large with blades that are longer than a football field to a small turbine with rotors that are 8-25 feet in diameter. Small turbines can be used for home powering or water pumping. Surprisingly, wind energy is abundant in much of the U.S. and vary from wind power density classes of 1 to 7, the highest. It’s a free and renewable resource, and is clean, much like the solar power panels that are being used. Solar power in Long Island and top New York solar panels are helping these areas to run cleaner than ever before, with some of the best solar panels Long Island New York getting the job done and leading the way for the nation.
Wind energy will always be around to be harvested and one of the great benefits of this resource is that it does not pollute when utilized. No greenhouse gases are emitted by this resource and California’s wind power plants in 1990 offset more than 2.5 billion pounds of carbon dioxide in addition to 15 million pounds of pollutants. The cost of producing wind power has increased in the past decade, taking a greater initial investment than fossil fuels require, with 80% of the cost being machinery but come with minimal operating expenses. Concerns about wind plants include the rotor blade noise and birds and bat mortality, but these have been counteracted with technology and properly sitting plants. Ultimately, the greatest challenge to this resource being used for power is that the wind is not a constant source of power and wind cannot be stored, although its generated power can be. However, with all its advantages, wind power may just be the next power resource, and a clean and planet-friendly one at that.
We have been utilizing wind power for quite some time. At first the wind energy was used to pump water that was used for irrigation in Holland. Apart from pumping water the energy can also be used to grind grains. Due to advancement in technology the wind energy has been used to run wind turbines which can be used to generate electricity.
In order the wind turbines to be able to capture the highest possible wind energy they are mounted on towers where there is strong winds. The towers are usually built to a height of above 30 meters. At elevated highest the wind turbines are able to capture winds that are free from turbulent. The blades available on the wind turbines are able to capture the maximum amount of wind energy at elevated heights. When two or more blades are fixed on a shaft they end up forming a rotor.
During the operation of the blades they act like airplane wings. As the wind blows a low pressure pocket is formed on the downside which pulls the blades making the rotor to turn. This results into a lift. On the front side the lift is more than the wind force. This is called the drag. Due to the combination of the drag and lift, the propeller is forced to spin. The spinning shaft leads to the formation of electricity after it turns the generator.
In the production of wind power from the wind turbines they can be used as stand-alone or connected to the grids to supply a wide area. In some cases they can be used in combination with photovoltaic cells to produce more electricity. Several wind turbines can be built in a given area to form a power plant. For stand-alone turbines, they are mostly used in communication or pumping water to settlement schemes.
The world’s oil resources are getting strained because oil wells and reserves are becoming deeper and deeper making the drilling process tougher and expensive. This causes the hike in oil prices generating what is normally called energy crisis. To avert this, the world has undertaken another part in trying to satisfy its energy demands by going for greener methods including wind power solutions. Wind energy has been utilized in many parts of the not only to generate electricity but also to draw water from wells in desert areas. Wind is a natural resource which can be harnessed by using wind turbines. Although this venture can be expensive initially, it provides a long lasting solution to the dependence of the oil which its utilization leads to production of greenhouse gases including carbon dioxide.
How Wind Energy is Generated
Basically, wind power is trapped using wind turbines. These turbines are composed of three large propellers mounted on a sturdy pole. The faster the speed of the wind, the more energy it is generated. The turbines convert the mechanical wind energy into electrical energy which is then delivered to homes. Normally, excess energy can be fed back to the power grid.
Advantages of Wind Energy
- It is renewable and readily available natural resources
- It is green, that is, it doesn’t generate the harmful greenhouse gases
- It is free and a power company pays you back in case you’ve extra power
- There are tax incentives meant to promote wind energy
Disadvantages of Wind Energy
- Startup costs are high
- The wind resource may not be abundant everywhere
- It needs huge amount of land
- Some building codes may impair installation of turbines
- Wind turbines are normally noisy
- Blades have proved to be hazardous to birds
- The blades sometimes can be damaged by lightning storms
- Most turbines operate at 30% efficiency
Installing wind turbines in your home to harness wind energy may be expensive initially, but this will pay back in just a few years. Remember that you’ll not only save our environment from the dangerous greenhouse gases but you’ll also save yourself from the huge electricity bills that often strain your long island solar energy budget.
