INDUSTRIAL REVOLUTION - The main features involved were technological, socioeconomic, and cultural. The technological changes included the following:
• (1) the use of new basic materials, chiefly iron and steel,
• (2) the use of new energy sources, including both fuels
and motive power, such as coal, the steam engine,
electricity, petroleum, and the internal-combustion engine.
• (3) the invention of new machines, such as the spinning
jenny and the power loom that permitted increased
production with a smaller expenditure of human energy.
