University Ahmadabad, Gujarat, India ---------------------------------------------------------------------***--------------------------------------------------------------------- Abstract- Every day, new methods are being created to produce power using renewable energy. Similar to solar, wind, hydro, and nuclear energy. This paper examines the fundamental behaviour, analysis, and design of on-shore wind turbines used to generate renewable energy. It has the top five windiest cities in Gujarat, including Bhuj, Okha, Porbandar, Mundra, and Jamnagar. The primary objective of this master's thesis is to investigate and assess several types of foundation techniques for on-shore (on-land) wind turbines. The thesis would address both geotechnical and structural design, and it will be created in compliance with IS code, an Indian standard. We'll compare the various foundation kinds in terms of their behaviour, functionality, and other elements. In Gujrat state, a wind turbine 130 meters tall is installed on a variety of soil types. The study of the design, analysis, and behaviour of spread foundations and pile raft foundations using various types of piles is presented in this thesis. The Finite Element Method, ARCGIS, and PLAXIS-2D/3D Software are used to comprehend structural mechanics, structural and geotechnical design. Key Words: Renewable energy, Indian standards, i.e. IS code, geotechnical and structural design, basic behavior, analysis of on-shore type of Wind Turbines, behaviors, functionality, and other factors, 130m tall wind turbine , various types of Soil conditions, spread foundation and pile raft foundation, Finite Element Method, ARCGIS software, PLAXIS-2D/3D Software. 1. INTRODUCTION The supply of coal, oil, natural gas, and other conventional energy sources is limited, and if they were to exhaust at the rate at which they are already being used, they would do so within a few decades. Living without energy, or more precisely without electrical energy, is quite challenging given the growth of society and our modern way of life. What might the answer to this be? Everyone agreed that the only option was to consider renewable or non-delectable sources of energy. Solar, wind, biomass, tidal, geothermal, ocean thermal, etc. are the main sources of renewable energy (RE), according to the list. Conventional methods of producing power by burning coal, oil, and natural gas are swiftly depleting their supply of resources. Energy famine is quite likely to occur in several places in the near future. To meet the growing need for electricity in a sustainable manner, wind energy is acknowledged as one of the most cutting-edge, cost – effective, and tried renewable energy alternative. Despite the fact that onshore wind energy technology has advance to the point of large-scale deployment and has become competitive with fossil fuel- based electricity generation, with supportive policy regimes around the world, offshore wind energy development has not yet reached the same level of exploitation as onshore wind energy.

Wind turbine are used in several countries to reduce energy prices and rely less on fossils fuels. They represent a large Source of erratic renewable energy. Charles F Brush invented the first wind turbine that generated electricity in 1888. With very few exceptions, wind turbine do not release pollutants into the atmosphere or require water for cooling. Additionally, the usage of fossil fuels to produce energy be reduce thanks to wind turbine, which would reduce total air pollution and carbon dioxide emissions. In 1986, Tamil Nadu, Gujrat, and Maharashtra’s coastal regions saw the construction of Indies first wind farms, which included 55Kw vistas wind turbines. The capacity has significantly increased during the last five years. The 140-m tallest wind turbine in India was built in the Jamnagar district by SUZLON.
