Wind energy is the fastest growing source of renewable energy in the world. It has an average growth rate of 30%. In terms of wind wind energy production, after USA, Germany, Spain, and China, India occupies the fifth place in the world. There are many issues concerned in the distribution of energy to the definite location where larger scale productions are concerned therefore cost effective solutions have been found at smaller scale . The Integrated Roof Wind Energy System is considered to overcome the existing issues of urban and larger scale renewable energy system. The system is built by using skewed shaped funnels set in an axial array and its function involves acceleration of the wind flow by making use of the Venturi Effect. This leads to a converging air capturing inlet which is carefully designed with innovative shape and geometry to create high wind mass flow and velocity toward a vertical-axis wind turbine on roof top for comparatively high amount energy generation. This review presents an overview of the challenges to large scale wind power development in India and the scope for introducing Intergrated Roof Wind Energy System (IRWES). KEYWORDS: Integrated Roof Wind Energy System , venturi-effect, louvers, Vertical Axis Wind Turbine INTRODUCTION A promising renewable energy policy development has become a mission among the world wide researchers and governors due to rise in prices for fossil fuels, an increase in energy consumption, and electricity, global climate change,environmental disasters, etc.[9].Wind energy generation is an inexhaustible resource availability and is considered as the most attractive technology, while considering the ecological value and economical prospects. It has the potential to moderate the cost of electricity, to scale down the emissions of CO2 from power industries and decrease the reliance on costly fossil fuels. Twenty two countries have more than 1,000 MW installed capacity. This development was led by the China, US, Germany, Spain and India, and it brought global cumulative installed capacity to 2,82,482 MW (as of 30 June 2012). The top five countries in terms of cumulative installed capacity are China (75,564 MW), the US (60,007 MW), Germany (31,332 MW), Spain (22,796 MW) and India (18,421 MW) [3]. BP Global has estimated that World proven oil reserves in 2010 are sufficient to meet 46.2 years of the global production [23]. MATERIALS AND METHODS Wind energy in India About 53% of electric power in India is generated from coal and lignite based steam thermal plants, which contribute a lot to air pollution. The need of the hour is a cleaner and renewable source of energy, in which off shore wind power can play a major role. India is one of the five largest wind energy markets in the world today. Renewable energy sources (excluding large hydro) represent 12.2% of India’s installed capacity, with 70% of this contribution coming from wind energy [13]. India is blessed with a coastline of about 7,600 km. Under a national wind monitoring programme, winds have been measured at 54 locations on the coastline In Wind Chronicle, 2008/09. The onshore wind power potential for India has been estimated as 15000 MW (<60 m depth). There are many potential sites in Indian waters and still this huge potential remains untapped (Awesome Inc.,2011).The western coastline has modest potential at sea level. The southern tip of India starting from Kanyakumari up to Rameshwaram has shown some promising values. Rameshwaram indicates windpower density of 603 Wm-2 at 50 m agl and Kanyakumari has shown
