This book explores the development of the gas industry within Latin Europe (France, Italy, Portugal, and Spain). Through charting the growth of this industry during the 19th and 20th centuries, the technology and public policies used are examined to highlight the long term impact of the industry. Utilising a comparative analysis, similarities and variation between the development of gas within the Latin European countries is compared and contrasted with the aid of specific case studies. This book aims to place the development of gas resources in Latin Europe within a global perspective that takes into account the development of energy resources in the rest of Europe and the world more generally. It will be of interest to students and researchers working within energy economics and economic history. The book forms part of the results of the research project ‘Gas in Latin Europe: a comparative and global perspective (1818-1945)’, financed by theMinistry of Science and Innovation of the Spanish Government and ERDP Funds.
