Grey swan

Last updated

A grey swan is an event that is known and possible to happen, but which is assumed to be unlikely to occur. [1] The term derives from black swan theory, which describes an event which is unlikely but unknown. [1]

In electrical engineering, gray swan refers to the kind of events that rarely happens but have great impact on power systems. [2]

The law of truly large numbers, attributed to Persi Diaconis and Frederick Mosteller, states that with a large enough number of independent samples, any highly implausible result is likely to be observed. Because we never find it notable when likely events occur, we highlight unlikely events and notice them more. The law is often used to falsify different pseudo-scientific claims; as such, it is sometimes criticized by fringe scientists.

<span class="mw-page-title-main">Black swan theory</span> Theory of response to surprise events

The black swan theory or theory of black swan events is a metaphor that describes an event that comes as a surprise, has a major effect, and is often inappropriately rationalized after the fact with the benefit of hindsight. The term is based on an ancient saying that presumed black swans did not exist, until they were discovered in Australia in 1697, and it then became reinterpreted to mean an unforeseen and consequential event.

According to the Iran Petroleum Ministry, the proved natural gas reserves of Iran are about 1,201 trillion cubic feet (34.0 trillion cubic metres) or about 17.8% of world's total reserves, of which 33% are as associated gas and 67% is in non associated gas fields. It has the world's second largest reserves after Russia. As it takes approximately 5,850 cubic feet (166 m3) of gas to equal the energy content of 1-barrel (0.16 m3) of oil, Iran's gas reserves represent the equivalent of about 205 billion barrels (3.26×1010 m3) of oil.
