For some decades now, ever since the emergence of electricity and the shift to the industrial era, millions and billions of cold cash go down, every year, into energy budget in the name of allocation. This is so because different models and energy structural designs have been put forward, for funding, by scientists and researchers working in the area of generating energy in an effort to meet the unending energy use of the ever-growing world population.
While the people of the world (especially in advance countries) keep welcoming these designs and proposals, they care more about the sustainability, reliability and efficiency ratio in judging what option to consider. Looking at the readily available nature of wind, it can be established safe to deal with as science has advanced in her findings to make wind another potential actor in the generation of electrical energy through the use and design of wind turbines for not only domestic use but also commercial purposes.
What are wind turbines?
A wind turbine is a specially crafted engineering device built to convert the wind’s kinetic energy into utility electrical energy. Investing in a wind-powered system has in recent time been praised for its unparallel sustainability and efficiency. According to Wikipedia, the online library, the smallest turbines are used for applications such as battery charging for auxiliary power for boats or caravans or to power traffic warning signs while slightly larger turbines can be used for making contributions to a domestic power supply while selling unused power back to the utility supplier via the electrical grid.
Materials and recent developments
Materials that are typically used for the rotor blades in wind turbines are composites, as they tend to have a high stiffness, high strength, high fatigue resistance, and low weight. Typical resins used for these composites include polyester and epoxy, while glass and carbon fibers have been used for the reinforcing material. Construction may use manual layup techniques or composite resin injection molding. As the price of glass fibers is only about one-tenth the price of carbon fiber, glass fiber is still dominant.
Advantages of using Wind Turbine
In terms of expenses in its construction, wind turbines are generally inexpensive. They will produce electricity between two and six cents per kilowatt hour, which is one of the lowest-priced renewable energy sources. And as the technology needed for wind turbines continues to improve, the prices will decrease as well. In addition, there is no competitive market for wind energy, as it does not cost money to get a hold of wind. The main cost of wind turbines is the installation process.
Wind turbines provide a clean energy source, emitting no greenhouse gases and no waste product. Over 1,500 tons of carbon dioxide per year can be eliminated by using a one-megawatt turbine instead of one megawatt of energy from a fossil fuel. Being environmentally friendly and green is a large advantage of wind turbines.
AMAZING FACT: Largest floating wind turbine
The world’s largest—and also the first operational deep-water large-capacity—floating wind turbine is the 2.3 MW Hywind currently operating 10 kilometers (6.2 mi) offshore in 220-meter-deep water, southwest of Karmøy, Norway. The turbine began operating in September 2009 and utilizes a Siemens 2.3 MW turbine.
