Energy is essential for human development and well-being. It powers our homes, industries, transport, communication, and many other aspects of our lives. However, most of the energy we use today comes from conventional sources, such as fossil fuels (coal, oil, and gas), hydroelectric power, and nuclear power. These sources have several drawbacks, such as limited availability, high cost, environmental pollution, greenhouse gas emissions, and geopolitical conflicts.




Non Conventional Energy Sources By Gd Rai Pdf Free 1138



Therefore, there is a need to explore and utilize alternative sources of energy that are renewable, clean, abundant, and affordable. These are called non conventional energy sources or new and renewable energy sources. They include solar energy, wind energy, biomass energy, geothermal energy, hydrogen energy, ocean energy, and nuclear fusion. These sources have many advantages over conventional sources, such as environmental sustainability, economic viability, social equity, and energy security.


One of the pioneers in the field of non conventional energy sources is Gd Rai, a former professor of mechanical engineering at Samrat Ashok Technological Institute in Vidisha, Madhya Pradesh. He has written a comprehensive textbook on this topic titled "Non-Conventional Sources of Energy". The book covers the basic principles, applications, advantages, disadvantages, and challenges of various types of non conventional energy sources. It also provides case studies and examples from India and other countries. The book is suitable for engineering students as well as professionals and researchers interested in this field.


The book was first published in 1988 and has been revised and updated several times since then. The latest edition is the sixth edition which was published in 2017 by Khanna Publishers. The book has 696 pages and costs Rs. 495. However, if you want to download the pdf version of the book for free, you can do so by following these steps:

Types of non conventional energy sources




There are many types of non conventional energy sources that can be used for various purposes. Here are some of the most common ones:


Solar energy




Solar energy is the energy that comes from the sun. It is the most abundant and widely available source of energy on earth. It can be harnessed in two ways: solar thermal and solar photovoltaic. Solar thermal systems use the heat of the sun to produce hot water, steam, or electricity. Solar photovoltaic systems use the light of the sun to generate electricity directly. Solar energy can be used for heating, cooling, lighting, cooking, water pumping, irrigation, communication, and many other applications. Some of the advantages of solar energy are: it is renewable, clean, free, and decentralized. Some of the disadvantages are: it is intermittent, variable, and requires large area and high initial cost.


Wind energy




Wind energy is the energy that comes from the movement of air. It is caused by the uneven heating of the earth's surface by the sun and the rotation of the earth. It can be captured by wind turbines, which convert the kinetic energy of the wind into mechanical or electrical energy. Wind energy can be used for generating electricity, pumping water, grinding grains, and other purposes. Some of the advantages of wind energy are: it is renewable, clean, abundant, and cost-effective. Some of the disadvantages are: it is intermittent, variable, noisy, and may affect wildlife and aesthetics.


Biomass energy




Biomass energy is the energy that comes from organic matter, such as plants, animals, and microorganisms. It can be obtained in various forms, such as wood, crop residues, animal wastes, municipal solid wastes, biogas, biofuels, and biochar. Biomass energy can be used for heating, cooking, lighting, electricity generation, transport fuel, and soil improvement. Some of the advantages of biomass energy are: it is renewable, carbon-neutral, versatile, and locally available. Some of the disadvantages are: it may cause deforestation, land degradation, air pollution, and food insecurity.


Geothermal energy




Geothermal energy is the energy that comes from the heat of the earth. It is caused by the radioactive decay of elements in the earth's crust and mantle. It can be accessed by drilling wells or tapping natural geysers or hot springs. Geothermal energy can be used for heating, cooling, electricity generation, and industrial processes. Some of the advantages of geothermal energy are: it is renewable, clean, reliable, and efficient. Some of the disadvantages are: it is limited to certain locations, expensive to develop, and may cause earthquakes and environmental damage.


Hydrogen energy




Hydrogen energy is the energy that comes from hydrogen gas (H2), which is the simplest and most abundant element in the universe. It can be produced from various sources, such as water electrolysis, biomass gasification, fossil fuel reforming 71b2f0854b
