During the past decades, global electricity consumption has significantly increased, primarily driven by the immense growth of industry, transportation, and communication means. This energy creation is obtained by igniting petroleum derivatives like coal, flammable gas, and oil. However, it has been estimated that these resources will be scarce in the coming decades, pointing to a global energy shortage in the future. Additionally, the exploitation of these resources results in the emission of highly polluting gases, exacerbating the warming of our planet. It is therefore impossible to continue without an energy-efficient approach. This current situation applies to all countries all over the planet, including precisely made nations that consume excess energy for their selective assumption of living, as well as farming countries that require significantly more energy to find a workable pace. To address this overall energy crisis and its basic normal results, the most recent thing in the energy region revolves around promoting alternative energy sources over regular ones. Fashionable recent decades, thermoelectric generators (TEGs) have emerged as a technology that has garnered substantial attention.
