Abstract - Wind energy is one of the major forms of
renewable energy resources found abundantly which is widely used as an alternative energy. Wind power is sustainable and the production of electricity using wind energy is increasing day by day due to lack of availability of fossil fuels. The energy can be converted into electricity by using vertical axis wind turbine (VAWT) and Horizontal axis wind turbine (HAWT). The vertical axis wind turbine is highly used for domestic applications where the volume of production is low and efficiency is optimal while the horizontal axis wind turbine is widely for larger volume of production requires huge investment and the efficiency is high. This paper focused on increasing the efficiency of using wind energy by producing large amount of electricity and reduces the space for installation. This can be done by combining the vertical axis wind turbine (VAWT) and horizontal axis wind turbine (HAWT) in a same tower. The combined vertical and horizontal axis wind turbine reduces the cost for larger volume of electricity generation.
The vertical axis wind turbine (VAWT) is used for domestic purpose and low volume of production. VAWT requires low cost investment and less space for the installation compared to HAWT [1]. The rotational axis of vertical axis wind turbine is perpendicular to the direction of wind. It can produce electricity at low wind speed. The maintenance of vertical axis wind turbine is quite easy compared to horizontal axis wind turbine. The efficiency of VAWT is optimal so it cannot be utilize for larger volume of production [3]. The main advantages of VAWT compared with HAWT are generation of electricity at ground level and the way of installation is simple.
Key Words: Wind energy, VAWT, HAWT, combined vertical and horizontal axis wind turbine, high efficiency.
1. INTRODUCTION Energy plays an important role in everyday life to carry out any task. The non-renewable energy resources such as oil, coal and gas are majorly used as energy nowadays. The main problem behind the non-renewable energy resources are not sustainable and create global warming which is hazardous to the environment. The renewable energy resources are best way to solve this issue. The renewable energy resources such as solar, wind, tidal and bio gas are available in abundant and sustainable which can be utilized for the requirement. Wind energy is the purest form of renewable energy which is available highly for the production of electricity. Wind is the natural resources which cannot affect the environment. Most of the countries including India understand the importance of wind energy and used as a primary source of renewable energy because of low cost compared to other renewable energy resources [6]. The wind energy is produced by converting the kinetic energy of atmospheric air into mechanical energy. The vertical axis wind turbine (VAWT) and horizontal axis wind turbine (HAWT) are the turbines used to convert the mechanical energy from the kinetic energy. Š 2017, IRJET

1.2 Horizontal Axis Wind Turbine The horizontal axis wind turbine (HAWT) is widely used for higher volume of production which requires huge investment and occupies more space for the installation compared with vertical axis wind turbine (VAWT). The rotational axis of horizontal axis wind turbine is parallel towards the direction of wind in order to generate electricity [3]. It requires large tower and blade to install and the transportation cost is nearly 20% of the equipment of the cost. Highly skilled labors are required to install the horizontal axis wind turbine. The production cost is low ISO 9001:2008 Certified Journal
