With the effects of climate change linked to the use of fossil fuels, as well as the prospect of their eventual depletion, becoming more noticeable, political establishment and society appear ready to switch towards using renewable energy. Solar power and wind power are considered to be the most significant source of global low-carbon energy supply. Wind energy continues to expand as it becomes cheaper and more technologically advanced. Yet, despite these expectations and developments, fossil fuels still comprise nine-tenths of the global commercial energy supply. In this article, the history, technology, and politics involved in the production and barriers to acceptance of wind energy will be explored. The central question is why, despite the problems associated with the use of fossil fuels, carbon dependency has not yet given way to the more ecologically benign forms of energy. Having briefly surveyed some literature on the role of political and corporate stakeholders, as well as theories relating to sociological and psychological factors responsible for the grassroots’ resistance (“not in my backyard” or NIMBYs) to renewable energy, the findings indicate that motivation for opposition to wind power varies. While the grassroots resistance is often fueled by the mistrust of the government, the governments’ reason for resisting renewable energy can be explained by their history of a close relationship with the industrial partners. This article develops an argument that understanding of various motivations for resistance at different stakeholder levels opens up space for better strategies for a successful energy transition.

National Energy Policy, is to increase energy diversification through efforts to use renewable energy such as renewable non-fossil fuels, especially wind energy until 2025. By utilizing renewable energy, the dependence on fossil fuels on the national energy supply system can decrease. Sumbawa Island has the potential for wind energy around 220 KW (assuming each location is built 10 units)

A elevada intermitência das fontes de energia renováveis condiciona a produção de energia elétrica, que continua a depender muito dos combustíveis fósseis. Uma vez que existe complementaridade por parte das fontes de energia renováveis, a sua integração conjunta é, sem dúvida, a melhor solução para reduzir esta dependência. Aliado a este facto, poderá coexistir um sistema de armazenamento por bombagem, capaz de gerar reservas hídricas, que serão aproveitadas quando a procura exceder a oferta energética. Procedeu-se ao desenvolvimento de dois modelos: um sobre custos de turbomáquinas e outro que visa o estudo do potencial de recuperação de energia de uma solução energética híbrida com armazenamento por bombagem combinado com fonte de energia eólica. Foram estudadas diferentes combinações para estas duas fontes de energia renovável, analisando o consumo satisfeito e a energia eólica não consumida, tendo-se concluído que o excedente de energia eólica pode ser aproveitado para bombagem. The high intermittence of renewable energy sources determines the production of electricity, which remains highly dependent on fossil fuels. Since there is complementarity between renewable energy sources, their joint integration is a potential solution to reduce this dependency. Consequentially, a pumping storage system capable of generating water reserves can coexist, which will be used when demand exceeds the energy supply. Two models were developed: one based on turbomachinery costs and the other based on the potential of energy recovery of a hybrid energy solution with pump storage combined with wind energy. Different combinations were studied for these two sources, analysing the satisfied consumption and the wind energy that is not consumed, in which it was concluded that the surplus of wind energy can be used by pumped storage.

The utilization of Renewable Energies plays the pivotal role in the environmental protection in the contemporary age, so that many countries have given the priority to such energies in their national programs, seeking the efficient methods or strategies to achieve such ambition. The study shows that the issue has been considered in Iran Plateau from the early ages. The recognition of windmills utilization experience in the eastern region of Iran and especially the southern part of Khorasan province and Sistan shows that the use of wind energy has been adapted with the daily needs of residents. Regarding the wind power transmission mechanism in the studied local windmills known as Asbad, a same mechanism in all three types of Asbads is recognizable. Based on the study main achievement, such a power transmission mechanism can be applied in the contemporary age even in other countries to replace the energies derived from the fossil fuels with the wind energy as a Renewable and Eco-friend Energy.

This chapter examines global energy trends, whether a global renewable energy transition is already taking place, and what steps are needed to further accelerate the global deployment of renewables. It first considers the expansion of renewable energy in light of global energy trends, noting that a global energy transition is not yet a reality but is urgently needed. It then looks at drivers and barriers for an accelerated expansion of renewable energy and proceeds by discussing how renewables are moving from the sidelines to the center stage of global energy governance. In particular, it describes the politics behind the creation of the International Renewable Energy Agency (IRENA), an intergovernmental organization on renewable energy, as well as current challenges for global governance on renewable energy. The chapter shows that global renewable energy capacities have grown significantly but that global energy supply is still dominated by fossil fuels.

Wind is a renewable energy source and its use does not produce toxic substances such as fossil fuels. This is one of the most efficient forms of energy, it can become one of the main energy sources for future generations. Wind energy is one of renewable energy, which is widely used when the device is mass-produced, assembly technology is completed. Developed industrial countries have developed strategies to more actively exploit wind power in the future and gradually replace traditional energy sources such as coal, hydropower, nuclear. This paper examines wind power, applicability, general development trend in the world and assesses from an economic and environmental perspective as well as some recommendations on wind energy development in Vietnam.

Indonesia is known as the largest economy in South East Asia and as one of the emerging lower-middle-income countries. Before the pandemic Covid-19, Indonesia forecasted its GDP growth to increase to 5.5% in 2020. However, this never happened following the pandemic it decreased to 2.97% in the first quarter of 2020. This paper focuses on the renewable energy role in accelerating the economic recovery in Indonesia by emphasising the role of justice in the transition process. We conduct systematic reviews from different sources, both primary and secondary resources. We qualitatively analyse the energy regulation and energy road map in Indonesia as well as some academic research articles. Indonesia has developed its general energy plan related to the energy mix demand and supply, which includes a long-term plan on developing renewable energy sources and reducing the use of fossil fuels. As the fourth most populated country in the world, Indonesia still focusses on cheap energy supply and energy access to fulfil the energy demand. Therefore the transition process in Indonesia is considered slow compared to the OECD countries. There is a significant role of energy in economic growth, both energy consumption and energy resources. Until now, fossil fuels have dominated the Indonesian energy supply and demand. This paper highlights the role of renewable energy in the economic development of the country. This paper suggests that the pandemic has highlighted the energy transition movement in Indonesia. The Covid-19 has driven more research on the role of renewable energy project to the economic development and demonstrate that a transition to a low-carbon economy could contribute to the economic recovery in a justice way in many sectors. Renewable energy development contributes directly to human resources development, and this development also contribute to health sector improvement. Finally, this renewable energy development could accelerate the economic recovery in Indonesia and reach 5.2 to 5.6% in 2021.

The Taiwanese government has set an energy transition roadmap of 20% renewable energy supply by 2025, including a 20 GW installed PV capacity target, composed of 8 GW rooftop and 12 GW ground-mounted systems. The main trend of feed-in tariffs is downwards, having fallen by 50% over a ten-year period. Predicting the future ten-year equity internal rate of return (IRR) in this study, we examine the investability of PV systems in Taiwan when subsidies and investment costs descend. We have found that the projected subsidies scheme favours investment in small-sized PV systems. Unless the investment costs of medium-sized PV systems fall or subsidies rise over the next decade, investing in medium-sized PV systems will be less attractive. Nonlinear and linear degradation causes slight IRR differences when using higher-reliability modules.
