Pros of Wind Energy
While it might seem odd the hype behind wind energy is warranted. Wind energy can be a very practical energy system, especially when it’s used on a large scale. It has several advantages to offer.
Cons of Wind Energy
If wind energy is so great, why is it taking so long to catch on? The reason is that wind energy, like everything else, comes with its own set of flaws, and while they might seem trivial compared to the big picture, they can be very taxing in the moment.
Energy Resources: Wind
Many of the energy resources on Earth are shrinking, and renewable energy will likely replace them. One of the most popular types of renewable energy is wind power.
What is the role of wind turbines in the future?
important role in future national energy scenario [3] and its. use for electricity generation will continue to grow worldwide, as many countries are planning for its future de ployment . Wind turbines convert the kinetic energy (present in the wind) into mechanical energy which is available in form of rotation.
Why is the probability distribution of wind speed important?
The probabilistic distribution of wind speed is one of the important wind characteristics for the assessment of wind energy potential and for the performance of wind energy conversion systems. When the wind speed probability distribution is known, the wind energy distribution can easily be obtained. Therefore, the probability distribution of wind speed is a very important piece of information needed in the assessment of wind energy potential. For this reason, a large number of studies have been published concerning the use of a variety of probability density functions to describe wind speed frequency distributions. Two parameter Weibull distribution is widely used and accepted method. Artificial neural networks (ANN) can be used as alternative to analytical approach as ANN offers advantages such as no required knowledge of internal system parameters, compact solution for multi-variable problems. In this investigation adaptive neuro-fuzzy inference system (ANFIS), which is a specific type of the ANN family, was used to predict the annual probability density distribution of wind speed. The simulation results presented in this paper show the effectiveness of the developed method.
Why is it important to optimize the power produced in a wind turbine?
To optimize the power produced in a wind turbine, it is important to determine and analyze the most influential factors on the produced energy.
How much energy is needed to make tea?
To produce one kg of tea requires thermal and electrical energy in the range of 4.45-6.84 kWh and 0.4-0.7 kWh respectively .
How does wind energy affect the environment?
The principal environmental impact issues relating to wind energy have been noise, visual impacts, safety and impact on wildlife and natural habitats, electromagnetic interference, and energy costs of materials. Wind power generated worldwide is playing a significant role in mitigating the problematic effects of climatic changes resulting from burning of fossil fuel. It is suggested that engineers and politicians should be able to demonstrate that every reasonable care is being taken and the benefit of non-polluting wind generators will outweigh any environmental disadvantage.
Which parameter is the most influential?
pitch angle is one of the most influential parameter.
Is wind energy renewable?
Wind energy is a clean and renewable source of energy which can be utilized in meeting the increasing demand for electrical energy. International Energy Agency (IEA) has identified it as key element to reduce fossil fuel dependency and helpful tool to combat global warming.
What is the capacity factor of wind turbines?
Capacity factor means how often the wind turbine makes electricity. For example, a wind farm in North Dakota that is capable of generating 200 megawatts of electricity in ideal conditions will only create 80 megawatts of electricity on average because the wind does not always blow.
What does it mean to sit on a wind turbine?
Siting a wind turbine means that engineers must carefully consider where the best wind speeds are and also where there will be the least amount of impact to humans and wildlife.
Why are additions to the transmission grid needed?
Additions to the transmission grid are needed in order to expand the wind industry, which raises the cost of new wind farms.
Abstract
Wind energy is the most abundant, if not the cleanest, energy available on the Earth. The only obstacle is that it is chaotic and uncontrollable. With rise in demands for renewable energy and the stability of other renewable energy sources, the next logical step would be to harvest wind energy out of thin air.
1 Introduction
Energy is essential. The very core of the world runs on energy in one form or another. Be it thermal, electrical, chemical, kinetic, potential or even nuclear, energy is the very essence that keeps the world alive and moving forward. However, it is also malleable and easily transformed from one form into another wasted form.
2 Challenges
This section aims to generalize the challenges faced by wind energy harvesting and encompasses political initiatives, societal hindrance and environmental impacts. After this section, it is hoped that a thorough understanding on these challenges will open new ways to innovate the wind energy industry.
4 Malaysia
A study by Suzana et al. [ 23] to determine the developments of renewable energy sources in Malaysia shows that wind energy is highly inefficient with an efficiency score of 0.001. The highest mean efficiency score is 0.686 which points towards mini hydro. This can be attributed to several factors such as political, societal and environmental.
5 Conclusion
The wind energy industry needs more attention to further develop and overcome the various challenges proposed by this paper. This would include clearer policies, innovating wind turbines and revamping the education system to produce more skilled workers.
