Chapter Overview:
This chapter discusses the various sources of energy used in our daily lives and industries, broadly categorizing them into conventional and non-conventional sources. It provides a detailed look at conventional sources like fossil fuels (coal and petroleum), thermal and hydroelectric power plants, and discusses improvements in traditional methods like biomass and biogas generation. The chapter heavily emphasizes the urgent need to shift towards renewable and eco-friendly non-conventional sources to meet future energy demands and reduce environmental pollution. It explores solar energy, wind energy, tidal and wave energy, ocean thermal energy, geothermal energy, and nuclear energy. Finally, it highlights the environmental consequences of using different forms of energy and stresses the importance of choosing sustainable sources for a greener future.
