This paper is an enquiry into the role of State policies in influencing wind installed capacity. The paper studies the impact of policies on deployment of wind potential across the States of India over two decades. Aggregate indices are computed for each of the seven wind resourceful States of India indicating attractiveness for installed capacity of wind energy. For computing the indices, four policies, Feed-in-Tariff, Renewable Purchase Obligation, Banking facility, and Wheeling charges are considered. Panel data techniques are then employed to investigate the impact of the policy differences on wind potential deployment over the 19 year period (1993–2012) after controlling for three State-specific factors. The controlling factors include per-capita income of the State, power deficit, and ratio of installed capacity of wind to geographic potential indicating unmet capacity. The results show that that policy index positively impacts wind deployment whether control variables are included or not. Moreover, the control factors like the per-capita income of the State and unmet capacity have positive influence over the investment in wind energy. [ABSTRACT FROM AUTHOR]

Abstract: This paper aims to advance research into the effectiveness of policies for encouraging technological transition in the energy sector (in general) and wind power (in particular). It contends that the ineffectiveness of wind power development policy in most nations stems from a linear approach to policy design that is unsuited to complex adaptive markets. The paper argues that in complex adaptive markets, policies are required that foster competition on a level playing field. Insights are extracted from complexity theory to advance four principles for effective wind power policy in such markets. These principles include establishing policy initiatives to: encourage technological diversity, establish clear and progressive short to medium-term targets, enhance environmental monitoring systems and establish a malleable policy regime that directly resolves emergent challenges while simultaneously sustaining market momentum to ensure long-term targets are met. In order to demonstrate the applied relevance of these principles, the paper applies these concepts to a historical analysis of Denmark''s wind power development policies. [Copyright &y& Elsevier]

Acceptance plays an important role in the successful adoption of wind energy technology. This article identifies factors influencing the acceptance of wind energy and selects those factors which have the highest relevance for wind energy acceptance in Bavaria. We decided to analyze the Federal State of Bavaria in Germany as its current policy governance decelerates the building-up of wind turbines in this federal state. Using a qualitative approach, the results indicate that the perception of political processes, such as the recent enacting of the 10-H regulation in Bavaria, influences the acceptance towards wind energy, as trust and transparency in political processes are essential. In addition, the paper reveals the importance of the distributive justice, focusing in particular on the subitem envy, which can be considered on a neighboring or regional level. Additionally it reveals additional factors which are relevant for wind energy acceptance in the specific case of the analyzed federal state. [ABSTRACT FROM AUTHOR]

Abstract: Since 2005, there has been dramatic progress in China''s wind power industry. The annual growth rate of newly constructed capacity reached a miracle of 105% and the total installed capacity has increased from 1.27GW in 2005 to 44.73GW in 2010, which has exceeded the target of China''s energy long-term planning for 2020. During the 11th Five-Year-Plan (FYP), the Chinese government has issued a series of polices to promote and regulate the development of wind power industry, which is the underlying force driving its rapid development. This paper is a systematical review on the current status and policies of wind power industry in China. Firstly the current status including achievements and shortcomings is presented, and then the relevant polices and regulations released during the period of 11th FYP are reviewed. Meanwhile, the main approaches of the policies and regulations in promoting the development of wind power industry are discussed and the issues of the current policies are analyzed. Finally, the paper concludes on the perspectives of wind power policies in China. [Copyright &y& Elsevier]

In recent years, the Malaysian government has attempted to develop renewable energy (RE) through newly introduced regulatory supports after 30 years of failure to achieve a greater than one percent non-hydroelectric RE share in the total power mix. The government is currently assessing the onshore wind energy potential in Malaysia to determine the possibility of including wind energy in its FiT scheme. However, wind energy development in this low-energy location is not as straightforward as it would seem. Many previous wind studies in Malaysia have relied on poor data and simplistic or inadequate methodologies, resulting in grossly inaccurate estimates of wind potential. Moreover, two wind turbine generator demonstration projects executed by the government have failed. However, above all, the greatest factor impairing the progress of RE development in Malaysia is the weak and uncertain political support of these efforts. This lack of robust support is particularly true where fossil fuels are still heavily subsidised amid the subsidy reform in 2013. A review of global wind energy development shows that successful projects depend heavily on a sound and robust regulatory framework supported by strong and consistent political will. This dependence is not observed in Malaysia, where the government continues to subsidise private independent fossil fuel power producers but levies taxes on electricity consumers to fund RE development. These levies do not effectively support RE development, given the magnitude of the RE fund compared to fossil fuel subsidies. In the absence of strong and sincere political will, the progress of RE development in Malaysia has been notably slow. As a result, the prospect of wind energy development in Malaysia currently remains vague. This paper discusses the above issues in detail and recommends selected regulatory mechanisms based on the global experience of supporting RE development in Malaysia. [ABSTRACT FROM AUTHOR]

With the rapid development of human society, the demand for energy has accordingly increased, and along with this increasingly serious energy and environmental crises have developed. Many countries have been focusing on new energy resources to combat these crises, and offshore wind energy resources are especially attractive; they are safe, non-polluting, renewable, and widely distributed with large reserves, which has made them become the focus of developed countries. However, the distribution of wind energy has strong regional and seasonal differences, which determines the success and efficiency of wind energy developments. Therefore, there is a clear need for “resource evaluation and planning in advance” in the wind energy development. Previous research has made a great contribution to the evaluation of offshore wind energy resources, mostly through analysis of the climatic characteristics of wind energy. In the actual development process of wind energy resources, these analyses of the climatic characteristics of wind energy provide a reference for site selection. However, after constructing wind farms, to aid their operation, there needs to be a more comprehensive understanding of other factors, such as the short-term forecasting and medium- to long-term predictions of wind energy. This paper reviews the research progress of the wind energy resource evaluations, and then considers where future research needs to focus, for the evaluation of wind energy resources. This mainly includes further analyses of the climatic characteristics of wind energy, short-term forecasting, medium- to long-term predictions, early disaster warning systems, the establishment of a wind energy development index (WEDI) and an integrated application system, in hope of providing a reference for offshore wind power generation, seawater desalination and other wind energy resource developments, and accelerating the industrialization and utilization of offshore wind energy. Doing this will alleviate the energy and environmental crises, and promote the sustainable development of human society. [ABSTRACT FROM AUTHOR]

RENEWABLE energy sources , *WIND power , *ENERGY economics , *ENERGY development , *ENERGY policy - Abstract
Integrating variable and non-dispatchable renewable power generation into existing power systems will have consequences for their operation and future expansion. These impacts will depend on two factors: (1) the variability of the total renewable power generation on different time scales and (2) the possibilities of accurately forecasting these fluctuations. In this paper, previous research on variability assessment and forecasting of solar, wind, wave and tidal energy resources is reviewed. The aim is to summarize the state of knowledge in each area and to compare the approaches used for the respective resources. For temporal variability, methods and models used for assessing the variability are surveyed, as well as what is known about the variability at individual sites and for larger aggregates of sites. For forecasting, an overview of forecasting methods for the different resources is made, and selected forecasting methods are compared over different time horizons. An important finding is that it is hard to draw strong conclusions from the existing studies due to differences in approaches and presentation of results. There is a need for further, more coherent studies that analyze the variability for the different resources in comparable ways, using data with the same resolution, and for studies that evaluate the smoothing effect and complementarity of combinations of several renewable energy resources. For forecasting, future research should suggest ways to evaluate forecasts from different renewable energy sources in easily comparable ways, using data from the same locations or regions, with the same temporal and spatial resolution, and with comparable metrics for the forecasting errors.

In recent time, the concern for grid integration of wind power has been a subject of discussion in the academic community. At present, the penetration level is still moderate for most grids to accommodate. As the penetration level increases, wind power may cause additional problems to the grid due to its intermittent nature. One of the intending solutions to this problem is the adoption of energy storage. This paper examines the state of the art energy storage technology options that are capable of mitigating wind power intermittency on the grid and their challenges. It also highlighted the existing policies that aided the development of wind power and discusses the limitations of its integration into the grid. It was found that, the ability of storage technology to be effectively utilised in mitigating the wind power intermittency depends on the ramp rate of the technology, response delay time, duration of storage, maturity of technology, installation cost, efficiency of the technology, its environmental impact and the suitability of the site topology. Therefore, no single storage technology is capable of providing total solution at mitigating the effect of wind power intermittency on the grid. The effectiveness of the storage technology lies in the hybridization of the storage technologies depending on the level of cost and technical requirements. [ABSTRACT FROM AUTHOR]

Abstract: Over the centuries, energy has been supplied by wood, coal, oil and natural gas, as well as by uranium. All these energy sources are limited and create pollution problems. This has led countries to focus on a sustainable and cleaner energy sources. Wind energy is rapidly emerging as one of the most cost-effective forms of renewable energy with very significant increases in annual installed capacity around the world. In this paper, authors have tried to review the current state of wind power utilization in Ethiopia. First, a brief overview is given on the Ethiopian electric power sector in order to gain insight into the main energy sources of the country and installed electric power capacities. Wind energy potential and current energy policy in Ethiopia were discussed respectively in the subsequent sections. Finally, short reviews of the ongoing and planned wind energy together with other renewable energy projects are given. Ethiopia, a country that relies on hydroelectric plants for the bulk of its power, is now developing significant wind energy capacities. Lack of reliable wind data covering the entire country has been one of the reasons for limited application of wind energy in Ethiopia, but recently studies have shown that Ethiopia has substantial potential to generate electricity from wind, geothermal and hydropower. Considering the substantial wind resource in the country, the government has committed itself to generate power from wind plants by constructing eight wind farms with total capacities of 1116MW together with a number of hydropower plants over the five year Growth and Transformation Plan (GTP) period from 2011 to 2015. This development of wind power is a part of the current energy sector policy of the country that aims at a five-fold increase in renewable energy production by the end of 2015.

Abstract: It is highly significant for China to improve its development of wind power. In order to promote the sustainable development, a more comprehensive evaluation of factors affecting the effectiveness of investment in the industry wind power is required to be conducted to formulate a relatively stable policy supporting mechanism for the development of wind power. Based on the green accounting framework, this paper evaluates a typical wind power project from economic, environment and energy alternative respects comprehensively. We simulate the main factors influencing cost and benefit of the wind power investment with the Monte Carlo method. Finally, we discuss how to promote wind power with respect to the concern of government, investors and environmentalists. [Copyright &y& Elsevier]

Abstract: Over the last decade there has been a rapid global increase in wind power stimulated by energy and climate policies. However, as wind power is inherently variable and stochastic over a range of time scales, additional system balancing is required to ensure system reliability and stability. This paper reviews the technical, policy and market challenges to achieving ambitious wind power penetration targets in Ireland’s All-Island Grid and examines a number of measures proposed to address these challenges. Current government policy in Ireland is to address these challenges with additional grid reinforcement, interconnection and open-cycle gas plant. More recently smart grid combined with demand side management and electric vehicles have also been presented as options to mitigate the variability of wind power. In addition, the transmission system operators have developed wind farm specific grid codes requiring improved turbine controls and wind power forecasting techniques. [Copyright &y& Elsevier]

Abstract: With regard to energy conservation and the reduction of emissions, China is dedicated to facilitating the development of renewable energy in order to fulfil its international responsibility. In recent years, the installed wind power capacity in China has increased rapidly due to its large scale and centralization. The high penetration of wind power has brought about a series of problems such as the wind energy utilization and curtailment, auxiliary services and the pricing mechanism. The resolution of these problems needs policies which will provide more support than the current technologies and standards for wind power. This paper takes the evaluation of capability of accepting large-scale wind power in China as its object of study. According to the analysis of such risk factors as the influence of the grid on wind power integration, wind power itself, the market and policy, an evaluation model of the ability of accepting large-scale wind power is established based on risk theory. Then, the estimation of the ability to accept wind power in Gansu Province is used to testify to the effectiveness of this model. Finally, a series of reasonable policies for wind power are proposed.
