Wind energy is a popular topic these days. The costs of traditional energy forms are increasing, which motivates people to look for cheaper and more reliable energy forms. It is necessary to be aware of wind energy as well as its usefulness when we discuss cheap energy alternatives.
While wind energy may appear to have many advantages over more traditional forms of energy, it too has a set of challenges that must overcome before it can be used in large-scale applications. If you're considering using this form of energy in your home or if you're just looking to learn more about it, this short article on will help you understand the basics.
1. It is virtually unlimited. As the Earth rotates it is heated and cooled by the sun, wind occurs as a natural part of this process.
2. It is readily available in many regions. While not all countries have the geography to make use of it efficiently, countries like the United States are investing millions to take advantage of this naturally occurring resource.
3. It is relatively inexpensive to things like oil and coal. With the exception of solar energy, all other forms of energy must be converted from their natural state to extract the energy within them. This process of conversion and extraction can be very expensive and manifests itself in kilowatt-per-hour costs. In competitive terms, wind has a lower cost.
1. It is intermittent. Although it's true that it is a natural byproduct of the Earth's rotation, there are still some periods in which went simply does not blow. Except for extreme cases, in regions were wind blows constantly, the fact that wind energy is intermittent means that a backup source of energy must be available at all times.
2. It is expensive to transfer. The most when the regions are generally very remote and sparsely populated. Due to their remote nature, the cost of transporting the harnessed energy is very high.
3. It has a high installation cost. The machinery required to capture wind power on a large scale, otherwise known as wind turbines, are very expensive. These massive structures often have blades which measure over 100 feet in length and consequently require enormous amounts of manpower to install.
