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

g. devices) using innovation by taking an input, altering it according to the system's usage, and after that producing an result are described as innovation systems or technological systems. The simplest kind of technology is the development and usage of basic tools. The prehistoric discovery of how to manage fire and the later Neolithic Transformation increased the available sources of food, and the creation of the wheel helped human beings to take a trip in and control their environment. Developments in historic times, consisting of the printing press, the telephone, and the Web, have lessened physical barriers to communication and enabled human beings to engage freely on an international scale.
It has actually assisted develop more innovative economies (including today's worldwide economy) and has permitted the rise of a leisure class. Numerous technological processes produce undesirable by-products called contamination and diminish natural deposits to the hinderance of Earth's environment. Innovations have actually always influenced the values of a society and raised new concerns in the ethics of technology. Examples consist of the increase of the idea of efficiency in regards to human performance, and the obstacles of bioethics. Philosophical disputes have actually arisen over using innovation, with disagreements over whether innovation enhances the human condition or aggravates it. Neo-Luddism, anarcho-primitivism, and similar reactionary movements slam the pervasiveness of technology, arguing that it hurts the environment and alienates individuals; supporters of ideologies such as transhumanism and techno-progressivism view continued technological development as advantageous to society and the human condition.
