    Rajasthan-State-Wind

    Wind Power Profile of Rajasthan State Profile Located on the north-western side of India, Rajasthan covers an area of 342,239 square kilometres and it comprises most of the wide and inhospitable Thar Desert (Rajasthan Desert or Great Indian Desert) and shares a border with the Pakistani provinces of Punjab to the northwest and Sindh to the west, along the Sutlej-Indus river valley. It is bordered by five Indian states: Punjab to the north; Haryana and Uttar Pradesh to the northeast; Madhya Pradesh to the southeast; and Gujarat to the southwest. State lies between 26.45°N Latitude & 73.30° E Longitude. The geographic features of Rajasthan are the Thar Desert and the Aravalli Range, which runs through the state from southwest to northeast, almost from one end to the other, for more than 850 kilometres. Mount Abu lies at the south-western end of the range, separated from the main ranges by the West Banas River, although a series of broken ridges continues into Haryana in the direction of Delhi where it can be seen as outcrops in the form of the Raisina Hill and the ridges farther north. About three-fifths of Rajasthan lies northwest of the Aravallis, leaving two-fifths on the east and south direction. The Climate of Rajasthan generally arid or semi-arid and features fairly hot temperatures over the year with extreme temperatures in both summer and winter. Due to the desert Geography, temperatures frequently climb above 40 to 450 Celsius in most places and the summer is the longest season. The cold weather commences early in October and comes to an end in the middle of January.

    Actors, Trends in Knowledge Production and Innovation in Indian Renewable Energy Sector: a Case of Solar and Wind Technologies

    International Association for Management of Technology IAMOT 2018 Conference Proceedings ACTORS, TRENDS IN KNOWLEDGE PRODUCTION AND INNOVATION IN INDIAN RENEWABLE ENERGY SECTOR: A CASE OF SOLAR AND WIND TECHNOLOGIES AMITKUMAR SINGH AKOIJAM Jawaharlal Nehru University (JNU), Centre for Studies in Science Policy (CSSP), India [email protected] ABSTRACT The main focus of this paper is to understand the nature, structure and dynamics of renewable energy sector with special focus on solar and wind energy by identifying various actors and institutions, and the trends in the production of scientific knowledge. We adopt Sectoral System of Innovation (SSI) framework for the study. The SSI approach has composed of various actors, agents, institutions, types and structure of interactions among firms and non-firms organizations. The main findings of the study are the number of research publications and granted patents has been increased gradually in both solar and wind technologies in the country. India ranks among the top ten country in terms of scientific knowledge production pertaining to the field of solar which stands at fifth position and wind energy at sixth position. In terms of R&D investment in both solar and wind energy the country is far behind others leading countries. Though, there is a significant presence of productive R&D organization, academia and supportive regulatory policy initiatives in both solar and wind energy sectors. Key words: Innovation; knowledge production; renewable energy; solar; wind; India. INTRODUCTION The study is motivated by the need to accelerate the supply of renewable energy with special focus on both solar and wind energy with a vision of affordable and reliable clean energy because it addresses the issue of climate change and fostering sustainable development in India.

    Wind Energy Is Already Playing an Important Role in India, and the Industry Has Established Capacities to Manufacture Large Numbers of Turbines

    Wind EnErgy india Slumbering giant Wind energy is already playing an important role in India, and the industry has established capacities to manufacture large numbers of turbines. Even so, the Union Government in New Delhi has to date been unable to reach a decision on a uniform system of incentives. ndia is one of the five most important wind energy markets in the world. The wind energy resources in Ithis enormous country are more than tempting, and the industrial potential is well developed. But neverthe- less, a wind energy boom has failed to materialise. Over the past few years, India has in fact lost touch with the global leaders. The Indian wind energy market is a world of its own, and there is only minimal trade with foreign partners. Only a few Indian manufacturers export their wind turbines, and there is at the same time very little in the way of imports. An effectively unknown spectrum of small and medium manufacturers is selling exclusively to the Indian market, for the most part in only small numbers. The renunciation of imports also applies to components. The Indian indus- try is itself able to produce rotor blades, transmissions, generators and hubs, and can thus essentially cover do- mestic demand. Several European suppliers have founded facilities of their own in India. LM Glasfiber, for example, manufac- tures rotor blades in two factories in Bangalore. Winergy Construction works in Maharashtra: New and Hansen Transmissions build wind turbine gearboxes turbine manufacturer Kenersys installs in India. And last year, SKF opened a production facility two of its K82 turbines with a capacity of for roller bearings in Ahmedabad (Gujarat), from which it 2 MW each.
