The consumption of conventional energy has increased exponentially due to the ever-increasing population of the world. Studies revealed that cooking activities contribute majorly to the overall energy consumption throughout the globe, further accounting for an increasing global warming potential. Being an enormous, virtually unlimited, and expandable source, solar energy turns out to be a favorable solution to the situation. Solar energy's widespread availability and processing technologies make the thermal energy conversion process easily accessible. Hence, solar energy has emerged as a ‘natural solution’ to the energy crisis and the adverse environmental impact, such as the greenhouse effect. This chapter outlines the various solar cooker fundamentals and development in different types of solar cookers, namely box type, panel, funnel type, parabolic type, and indirect type, along with the application of different solar cookers.
