Global Primary Energy Sources and Their Carbon Intensity

This chapter provides a comprehensive overview of the various energy sources that drive the world's energy systems, along with an analysis of their carbon intensity. It examines the major sources of primary energy, including fossil fuels (coal, oil, and natural gas), renewable energy sources (solar, wind, hydroelectric, biomass), and nuclear energy, discussing their availability, accessibility, and environmental impact. The chapter also evaluates the carbon intensity of each energy source, highlighting the differences in greenhouse gas emissions associated with their production and consumption. Through a detailed analysis of global energy sources and their carbon intensity, the chapter aims to inform policymakers, researchers, and industry stakeholders about the challenges and opportunities in transitioning to a low-carbon energy future.
