3.1 Introduction

Energy has occupied a predominant space in the existence and development of mankind. However, humans seek more and more sources of energy from the time immemorial. The demand of energy has drastically increased with the growth in population. To meet the energy requirements, there is a constant search for the alternate sources of energy. In the quest of meeting energy requirements, one should also be considerate towards its effects on the environment. At present, most of the energy requirements are fulfilled by non‐renewable resources. However, these resources suffer from several disadvantages like limited availability, long time duration for their formation and non‐sustainable, greenhouse gas emissions. The emission of carbon dioxide, methane and other harmful gases that are the main cause of global warming may result change in the weather patterns which in turns affect the ecosystems (Wang et al. 2020a). Apart from the air pollution, excessive usage of fossil fuels results in water pollution, land pollution, climate change etc. All these pollutants severely affect the human health and environment.
