This book provides a close analysis of the changes in the global oil and gas industry and the new energy industry. It offers a deep exploration of various sectors such as the global oil industry, natural gas industry, new energy industry, low-carbon market, and electricity market. Since 2023, there have been significant adjustments in the global energy market. The geopolitical situation in the Middle East is unstable, resulting in fluctuating international oil prices and a profound transformation in the trade flow of crude oil. Additionally, the global natural gas trade pattern is undergoing reshaping. China is accelerating the construction of a new energy system with the gradual increase in the proportion of renewable energy consumption, the development and improvement of the domestic carbon market, and the gradual expansion of green electricity trading. This book aims to provide a comprehensive overview and trend forecasts of the energy sectors for professional readers in the field, as well as to offer recommendations on how to respond to these developments.
