Non Conventional Energy Sources by G.D. Rai: A Comprehensive Guide
Non conventional energy sources are those that are renewable, natural and can be restored. They include solar energy, wind energy, tidal energy, biomass energy and geothermal energy. These sources of energy are becoming more important as the conventional sources of energy such as coal, oil and natural gas are depleting and causing environmental problems.
One of the books that provides a detailed overview of the non conventional energy sources is Non Conventional Energy Sources by G.D. Rai. This book was first published in 1988 and has been revised and updated several times since then. It covers the basic principles, applications and technologies of various non conventional energy sources. It also discusses the environmental impacts, economic aspects and policy issues related to these sources of energy.
The book is divided into 16 chapters, each focusing on a different non conventional energy source. The chapters are as follows:
Solar Thermal Systems
Solar Photovoltaic Systems
Ocean Thermal Energy Conversion
Magneto Hydro Dynamic Power Generation
Thermo Electric Generators
Thermo Ionic Generators
Environmental Aspects of Non Conventional Energy Sources
The book is written in a simple and lucid language, with diagrams, tables and examples to illustrate the concepts. It is suitable for undergraduate and postgraduate students of engineering, science and technology, as well as for professionals and researchers in the field of non conventional energy sources.
The book is available in PDF format for free download from various websites on the internet. However, it is advisable to purchase the original copy from the publisher or a reputed online store to support the author and get the latest edition of the book.
Non conventional energy sources have many advantages and disadvantages compared to conventional energy sources. Some of the advantages are:
Renewable and less expensive: Most non conventional resources are cheaper and can be reused as compared to conventional sources. They do not require any fuel cost and have low maintenance cost.
Environment friendly: Non conventional sources of energy do not emit harmful gases or pollutants that cause global warming, acid rain or smog. They also help in conserving the natural resources and biodiversity.
Diversified and decentralized: Non conventional sources of energy can be used in remote and rural areas where conventional sources are not available or feasible. They also reduce the dependence on foreign oil imports and enhance energy security.
Some of the disadvantages of non conventional sources of energy are:
Intermittent and unreliable: Non conventional sources of energy depend on natural factors such as sunlight, wind, water and biomass, which are variable and unpredictable. They may not be available at all times or in sufficient quantities to meet the demand.
High initial cost and technical challenges: Non conventional sources of energy require high initial investment for installation and infrastructure. They also face technical challenges such as storage, transmission and integration with the existing grid.
Limited potential and social impacts: Non conventional sources of energy have limited potential in some regions due to geographical constraints or lack of resources. They may also have negative social impacts such as displacement of people, land use conflicts or aesthetic concerns.
Therefore, non conventional sources of energy have both pros and cons that need to be considered before adopting them. They can complement the conventional sources of energy and provide a sustainable and clean alternative for the future. 061ffe29dd
