Heraean Mountains
The Herean Mountains (also influenced by Italian as ''Erean'') ( scn, Munti Erei; it, Monti Erei; la, Heraei montes) are a mountain chain in central Sicily, southern Italy, mostly located in the central and northern areas of the province of Enna. The highest peak is the Monte Altesina, at 1,192 m above sea level. Description The Herean Mountains are of limestone origin, and do not reach high altitudes. Their area was once one of the most important in the world for the production of sulphur, as testified today by numerous mineral quarries, the largest being that of Floristella-Grottacalda. There are several lakes in the mountain group, such as Pergusa Lake, whose rich bird life has given it the status of being the first special Natural Reserve in Sicily, and Pozzillo Lake, the largest artificial basin on the island. Due to the rugged landscape, the population totals less than 200,000 and thus the area's population density is lower. The chain is home to the largest Italia ...

Energy Returned On Energy Invested
In energy economics and ecological energetics, energy return on investment (EROI), also sometimes called energy returned on energy invested (ERoEI), is the ratio of the amount of usable energy (the ''exergy'') delivered from a particular energy resource to the amount of exergy used to obtain that energy resource. Arithmetically the EROI can be defined as: : EROI = \frac. When the EROI of a source of energy is less than or equal to one, that energy source becomes a net "energy sink", and can no longer be used as a source of energy. A related measure, called energy stored on energy invested (ESOEI), is used to analyse storage systems. To be considered viable as a prominent fuel or energy source a fuel or energy must have an EROI ratio of at least 3:1. History The energy analysis field of study is credited with being popularized by Charles A. S. Hall, a Systems ecology and biophysical economics professor at the State University of New York. Hall applied the biological meth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enna
Enna ( or ; grc, Ἔννα; la, Henna, less frequently ), known from the Middle Ages until 1926 as Castrogiovanni ( scn, Castrugiuvanni ), is a city and located roughly at the center of Sicily, southern Italy, in the province of Enna, towering above the surrounding countryside.

History Enna is situated near the center of the island; whence the Roman writer Cicero called it ''Mediterranea maxime'', reporting that it was within a day's journey of the nearest point on all the three coasts. The peculiar situation of Enna is described by several ancient authors, and is one of the most remarkable in Sicily. The ancient city was placed on the level summit of a gigantic hill, surrounded on all sides with precipitous cliffs almost wholly inaccessible. The few paths were easily defended, and the city was abundantly supplied with water which gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centuripe
Centuripe (Latin: Centuripae; Sicilian: Centorbi) is a town and ''comune'' in the province of Enna (Sicily, southern Italy).

It became an ally of the Athenians at the time of their expedition against Syracuse, and maintained its independence almost uninterruptedly (though it fell under the power of Agathocles) until the First Punic War when it immediately submitted to the Romans. It was thus granted Latin Rights before the rest of Sicily and was a (free city exempted from tax). In the 3rd and 2nd centuries BC Centuripe Ware was a distinctive class of Sicilian vase painting, with the unusual feature of fully coloured painting in tempera applied after firing was ...
