Non-Conventional Energy Sources by G D Rai: A Book Review
Non-conventional energy sources are those that are renewable, abundant and environmentally friendly. They include solar, wind, biomass, geothermal, hydro, tidal, wave and ocean thermal energy. These sources of energy have the potential to meet the growing demand of energy in the world and reduce the dependence on fossil fuels.
Non-Conventional Energy Sources by G D Rai is a comprehensive textbook for engineering students that covers the principles, applications and challenges of various non-conventional energy sources. The book is divided into 12 chapters, each focusing on a different source of energy. The book provides a detailed description of the working of each energy system, along with its advantages, disadvantages, limitations and prospects. The book also discusses the environmental impacts, economic aspects and social implications of using non-conventional energy sources.
The book is written in a simple and lucid language, with numerous diagrams, tables and examples to illustrate the concepts. The book also includes objective questions, review questions and numerical problems at the end of each chapter to test the understanding of the readers. The book is suitable for undergraduate and postgraduate students of engineering, as well as for professionals and researchers in the field of renewable energy.
Non-Conventional Energy Sources by G D Rai is a valuable resource for anyone who wants to learn more about the alternative sources of energy that can help us achieve a sustainable future.Non-conventional energy sources have many advantages and disadvantages compared to conventional energy sources such as coal, oil and gas. Some of the advantages are:
They are renewable and inexhaustible, meaning they will not run out in the foreseeable future.
They are clean and eco-friendly, meaning they do not emit harmful greenhouse gases or pollutants that cause global warming and climate change.
They are decentralized and distributed, meaning they can be generated and used locally, reducing the need for transmission and distribution losses and enhancing energy security.
They are cost-effective and affordable, meaning they have low or zero fuel costs and low maintenance costs, making them accessible to rural and remote areas.
Some of the disadvantages are:
They are intermittent and variable, meaning they depend on the availability of natural resources such as sunlight, wind, water and biomass, which may not be constant or predictable.
They have low efficiency and high capital cost, meaning they require large land area and high initial investment to install and operate.
They face technical and social barriers, meaning they require advanced technology and skilled manpower to operate and maintain, as well as public awareness and acceptance to adopt.
They have limited potential and scope, meaning they cannot meet the entire energy demand of the world or replace the conventional energy sources completely.
Therefore, non-conventional energy sources have both pros and cons that need to be weighed carefully before choosing them as an alternative to conventional energy sources. They can complement each other and provide a diversified and balanced energy mix that can ensure energy security, sustainability and affordability for all. 66dfd1ed39
