Wind power acts as a highly viable mechanical and electrical alternative to conventional power grids. The text emphasizes the aerodynamic principles required to harvest kinetic energy from moving air masses. 6 V May 2018 http://doi.org/10.22214/ijraset.2018.5055

G.D. Rai’s approach is holistic. He defines non-conventional energy sources as those that are not based on the burning of fossil fuels or the splitting of atoms (nuclear fission in its conventional, large-scale form). Instead, he focuses on flows of energy that are naturally replenished on a human timescale: solar, wind, biomass, hydro (small-scale), tidal, wave, geothermal, and hydrogen.

Collectors transform incoming solar radiation into useful thermal or electrical energy. G.D. Rai categorizes these systems based on their focus mechanics:

If you are using this book for an academic course or competitive exam, ensure you have the latest edition (e.g., 5th or 6th) to benefit from updated data on costs, efficiencies, and recent projects.

G.D. Rai is known for writing in a student-friendly, lucid style. The concepts are broken down into simple English, avoiding overly complex jargon where possible, which makes it accessible to students from various backgrounds.
