The basic mechanism driving social change is increasing awareness leading to better organization. When society senses new and better opportunities for progress it develops new forms of organization to exploit these new openings successfully. The new forms of organization are better able to harness the available social energies and skills and resources to use the opportunities to get the intended results.
Development is governed by many factors that influence the results of developmental efforts. There must be a motive that drives the social change and essential preconditions for that change to occur. The motive must be powerful enough to overcome obstructions that impede that change from occurring. Development also requires resources such as capital, technology, and supporting infrastructure.
Development is the result of society's capacity to organize resources to meet challenges and opportunities. Society passes through well-defined stages in the course of its development. They are nomadic hunting and gathering, rural agrarian, urban, commercial, industrial, and post-industrial societies. Pioneers introduce new ideas, practices, and habits that conservative elements initially resist. At a later stage, innovations are accepted, imitated, organized, and used by other members of the community. Organizational improvements introduced to support the innovations can take place simultaneously at four different levels—physical, social, mental, and psychological. Moreover four different types of resources are involved in promoting development. Of these four, physical resources are most visible, but least capable of expansion. Productivity of resources increases enormously as the quality of organization and level of knowledge inputs rise.

The second law of thermodynamics puts a fundamental limit on the thermal efficiency of all heat engines. Even an ideal, frictionless engine can't convert anywhere near 100% of its input heat into work. ... No device converting heat into mechanical energy, regardless of its construction, can exceed this efficiency.
