Energy: What is it?
To obtain wind power, the kinetic energy of wind is used to create mechanical power. A generator converts this power into electricity so that it may be used for the benefit of mankind. Recently, different types of electricity generation have been a frequent topic of debate amongst experts. Surely, wind energy is one of the frontrunners of the technological breakthroughs that might lead to more efficient energy production. At a glance, the future of wind energy seems promising. This may be the case, but there are also some disadvantages that must be considered.
Advantages
The advantages of wind energy are more apparent than the disadvantages. The main advantages include an unlimited, free, renewable resource (the wind itself), economic value, maintenance cost, and placement of wind harvesting facilities. First and foremost, wind is an unlimited, free, renewable resource. Wind is a natural occurrence and harvesting the kinetic energy of wind doesn't affect currents or wind cycles in any way. Next, harvesting wind power is a clean, non-polluting way to generate electricity. Unlike other types of power plants, it emits no air pollutants or greenhouse gases. The wind turbines harmlessly generate electricity from wind passing by. Wind energy is far more ecofriendly than the burning of fossil fuels for electricity. Currently, the United States, along with other countries, remains dependent on fossil fuels imported from unstable and unreliable nations. [1] Strains on supply (of fossil fuels) are likely to increase the prices of fossil fuel resources and leave the US economy exposed to international market volatility. Wind power has the ability to free the US from the figurative economic bondage of fossil fuels. Once turbines and energy centers have been installed, the cost of maintaining turbines and generating wind power is next to nothing. Another advantage of wind power is the ability to place turbines wherever necessary. After performing research and finding areas that have adequate wind, experts may place the turbines in desired areas. These areas are usually unpopulated (offshore wind turbines, for example). [1] In fact, offshore winds tend to blow harder and more uniformly than on land, providing the potential for increased electricity generation and smoother, steadier operation than land-based wind power systems. Fig. 1 shows offshore wind turbines harvesting energy.
Disadvantages
The two major disadvantages of wind power include initial cost and technology immaturity. Firstly, constructing turbines and wind facilities is extremely expensive. The second disadvantage is technology immaturity. [1] High cost of energy can, in part, be addressed directly with technology innovations that increase reliability and energy output and lower system capital expenses. Offshore wind energy produces more energy than onshore wind energy, but costs much more to establish. The primary costs of wind turbines include construction and maintenance. [1] New technology is needed to lower costs, increase reliability and energy production, solve regional deployment issues, expand the resource area, develop infrastructure and manufacturing facilities, and mitigate known environmental impacts. Therefore, one may argue that implementation of wind energy must be delayed until technological advancements are made.
