Productivity:

Productivity is the ratio of inputs to outputs—the value of what we put into the process compared with what we get out of the process. A production process has three main inputs: labour, capital (equipment and buildings), and purchased inputs (goods and services bought from other companies). The numerator of the productivity equation is value added (output minus the purchased inputs); the denominator, costs (capital costs plus labour). Labour productivity (value-added output per employee) and capital productivity (value-added output per dollar of capital stock) can be examined separately. Labour productivity is highly relevant to high-tech sub sectors, particularly software and services, because much of their productive capacity resides in people.

A company that has higher productivity will enjoy greater profitability with all else equal in a given market. A more productive company can either produce the same output with fewer inputs and thus enjoy a cost advantage or produce more or better output with the same inputs and command a price premium. Over time, the higher profitability of more productive companies will attract competition, and profitability will tend to converge. Profitability is thus a transient reward for improvements in productivity.

How to Get Free Electricity:

The Sun is an incredible source of energy that provides a free, renewable resource in the form of heat and light. Just 20 days of Sun energy can produce the same amount of energy as all of Earth's reserves of oil, coal and natural gas. Solar energy can be strapped up inactively through appropriate design principles as well as actively with collectors that capture the heat or light of the sun.
