Pubblichiamo di seguito per intero l'intervento pronunciato questo giovedì da mons. Giampaolo Crepaldi, Arcivescovo di Trieste già Segretario del Pontificio Consiglio della Giustizia e della Pace, in occasione della giornata di studio dal titolo “Per una rivoluzione verde dell'Africa. Lo sviluppo è il nuovo nome della pace”, promossa dall'Ateneo Pontificio “Regina Apostolorum” in vista della prossima Assemblea speciale del Sinodo dei Vescovi per l'Africa.

Global potential for wind-generated electricity Xi Lua, Michael B. McElroya,b,1, and Juha Kiviluomac aSchool of Engineering and Applied Science, Cruft Lab 211, and bDepartment of Earth and Planetary Sciences, Harvard University, 100E Peirce Hall, 29 Oxford Street, Cambridge, MA 02138; and cVTT Technical Research Centre of Finland, P. O. Box 1000, 02044 VTT, Finland Communicated by James G. Anderson, Harvard University, Cambridge, MA, April 29, 2009 (received for review November 6, 2008) The potential of wind power as a global source of electricity is assessed by using winds derived through assimilation of data from a variety of meteorological sources. The analysis indicates that a network of land-based 2.5-megawatt (MW) turbines restricted to nonforested, ice-free, nonurban areas operating at as little as20%of their rated capacity could supply >40 times current worldwide consumption of electricity, >5 times total global use of energy in all forms. Resources in the contiguous United States, specifically in the central plain states, could accommodate as much as 16 times total current demand for electricity in the United States. Estimates are given also for quantities of electricity that could be obtained by using a network of 3.6-MW turbines deployed in ocean waters with depths <200 m within 50 nautical miles (92.6 km) of closest coastlines.

È nota la loro propensione a cibarsi delle fasi larvali e di pupa delle zanzare. Sono molto resistenti, sopravvivono anche in acque con bassa presenza d'ossigeno, ad alta salinità (che includono due volte quella dell’acqua di mare) ed a temperatura elevata; possono persino sopravvivere in acque fino a 42 °C per brevi periodi.
