1.1 Introduction

The energy system needs substantial decarbonization to combat climate change (Fawzy et al. 2020). However, climate change itself is often affected by energy system components that include long‐term variations in climate parameters, instability and extreme weather situations (Field et al. 2014). Energy security and climate change are also genuine global issues, which also surface worldwide public policy debates. Significant international attempts to examine climate change policies have been undertaken in the past, in order to make them more conducive to the cause (Helm and Hepburn 2009; Giddens 2011; Held et al. 2011). In this ever‐changing research area, it is vital to review literature that quantifies impacts and evaluates how this information is used to develop energy systems models.

Multiple‐source energy use has always been a primary factor in human survival and civilizational growth. When comparing our ancestors’ energy consumption quantity and trend with modern society, significant changes can be observed. Hunter‐gatherer men’s daily energy needs were about 2500 kcal before the arrival of modern agricultural techniques to sustain their nutrition, storage and reproduction, while modern man’s requirements may exceed more than 100 times their ancestors, depending on their carbon footprint (Dias ...
