Application of scientific knowledge A steam turbine with the case opened. Such turbines produce the majority of the electricity utilized today. Electrical energy intake and living requirements are extremely associated. Electrification is believed to be the most important engineering achievement of the 20th century.  Innovation (" science of craft", from Greek, techne, "art, ability, cunning of hand"; and -,) is the sum of strategies, skills, techniques, and processes used in the production of items or services or in the achievement of goals, such as scientific examination. Innovation can be the understanding of strategies, procedures, and the like, or it can be embedded in devices to permit operation without detailed knowledge of their operations.
g. devices) using technology by taking an input, changing it according to the system's use, and then producing an outcome are referred to as technology systems or technological systems. The easiest type of technology is the advancement and use of fundamental tools. The ancient discovery of how to control fire and the later Neolithic Revolution increased the available sources of food, and the creation of the wheel assisted humans to take a trip in and control their environment. Developments in historic times, including the printing press, the telephone, and the Internet, have actually decreased physical barriers to interaction and enabled humans to communicate freely on an international scale.
It has helped develop more sophisticated economies (including today's international economy) and has permitted the increase of a leisure class. Many technological processes produce unwanted spin-offs understood as contamination and deplete natural deposits to the detriment of Earth's environment. Innovations have always affected the values of a society and raised new concerns in the principles of technology. Examples include the rise of the notion of effectiveness in terms of human efficiency, and the challenges of bioethics. Philosophical arguments have occurred over making use of technology, with disagreements over whether innovation enhances the human condition or aggravates it. Neo-Luddism, anarcho-primitivism, and comparable reactionary movements criticize the pervasiveness of technology, arguing that it harms the environment and pushes away people; supporters of ideologies such as transhumanism and techno-progressivism view continued technological progress as helpful to society and the human condition.
