Application of scientific understanding A steam turbine with the case opened. Such turbines produce most of the electrical power utilized today. Electrical energy consumption and living requirements are highly associated. Electrification is thought to be the most crucial engineering achievement of the 20th century.  Technology (" science of craft", from Greek, techne, "art, skill, shrewd of hand"; and -,) is the sum of methods, abilities, approaches, and processes used in the production of items or services or in the achievement of goals, such as clinical investigation.
