Some historians distinguish under this rubric a second phase of the industrial revolution lasting from the 1850’s to the beginning of the First World War.
This period is characterized by an acceleration of the pace of technological innovation and the rate of energy utilization. These factors made possible the production and distribution of electrical energy, the production of petroleum-fueled engines, the mass production of materials resources (e.g., steel, cement), and the assembly-line manufacture of consumer goods.
Major research efforts by historians concentrate on the new type of industries made possible by the generation and distribution of electrical power.
