G.D. Rai’s Non-Conventional Energy Sources is more than a textbook; it is a . It equips engineers with the tools to move away from centralized, polluting, and depleting energy systems toward decentralized, clean, and renewable ones. The book’s strength lies in its honest presentation of both the promise and the challenges of each technology—low energy density, intermittency, high initial cost, and storage needs.
