A British man named George Stephenson created the world's first locomotive. One of the greatest creations of the 19th century was the transcontinental railroad. The Central Pacific starting in San Francisco, and the Union Pacific, starting in Nebraska, would be the rail-line. The two railroads met at Utah and turned out to be a complete railway. Railroads was an extreme advance in society, not only for better transportation, but manufactured goods and raw materials needed quick transportation. The costs of products also decreased due to railroads, on the other hand, population increased due to the availability of food and low cost. These factors affected the entire Industrial Revolution. Thousands of people were employed in these factories and the lives of those people improved drastically.
The world, after the second half of the twentieth century, after the Second World War, entered a stage of profound technological developments in the field mainly triggered by the junction between scientific knowledge and industrial production. The third phase of the Industrial Revolution began in the mid-1940s, upcoming to the present day. This process was led by the United States of America, which became a major economic power in this period. One of its main appearances was the use of multiple energy sources such as petroleum, hydropower, nuclear, wind, etc. In this period, starts to increase, especially since the 1990s, the concern about reducing the use of polluting energy sources; also clean energy started to be a distress, and so, increased in the United States. The manufacturing process based on knowledge and research characterizes the so-called Third Industrial Revolution. At this phase or production stage, all the knowledge generated in research is passed on, almost simultaneously, for industrial development.
This third Industrial Revolution or Techno-Scientific Revolution enabled the development of activities in the industry that apply cutting edge technologies in all production stages.
