In nature, diversity is a source of ecosystem strength since failures are unlikely to eliminate all species. Therefore, the ecosystem will recover in some form and continue. In business or investing, diversity can provide a similar source of robustness against market instability or failures. Specifically, when applied to a human context, diversity refers to a […]

Discounted Cash Flow

A financial term referring to the value of an investment adjusted for the time value of money. Since money loses value over time, future cash to be received must be discounted to express its present value (today) in order to properly determine the value of a company or project under consideration.

Demand-Side Management

Also known as energy demand management, DSM is used in the electric utility industry as a technique to reduce peak demand under periods where the systems are constrained. This peak demand management does not necessarily decrease total energy consumption but does reduce the need for future investments in networks and/or power plants by increasing efficiency.

Each industry approaches this process differently and there are few standards. In addition, for small manufacturers, this is often seen as a time-consuming and expensive additional cost. This […]


Most recycled industrial nutrients (materials) lose viability or value in the process of recycling. This means they can only be used in a degraded form for components other than their original use. White writing paper, for example, is often downcycled into materials such as cardboard and cannot be used to create more premium writing paper.


In economics, converting future dollars into their present value. This can be a misleading indicator because, for example, when damage happens far in the future, discounting can make it seem less costly, such as with pollution or nuclear waste. Also, when benefits occur far in the future, their costs are often more difficult to justify […]
