Sago and New Guinea and is the primary source of sago. It tolerates a wide variety of soils and may reach 30 meters in height (including the leaves). Several other species of the genus "Metroxylon", particularly "Metroxylon salomonense" and "Metroxylon amicarum", are also used as sources of sago throughout Melanesia and Micronesia. Sago palms grow very quickly, in clumps of different ages similar to bananas, one sucker matures, then flowers and dies. It is replaced by another sucker, with up to 1.5 m of vertical stem growth per year. The stems are thick and are either self-supporting or have a moderate
Klaipėda Geothermal Demonstration Plant fuel, and reduce CO emissions by 51,940 tons, NO by 11 tons, and sulfur dioxides by 1,160 tons per year if it additionally replaced heavy fuel oil. According to this estimate, the plant would satisfy about 10% of the city's heat demand. The potential for geothermal heating using the source aquifer arises from the Gotland tectonic belt and Polotsk–Kurzeme fault belt interface in the area, which generates thermal anomalies. The plant uses water from a well drilled into a Devonian aquifer about beneath the surface. The heat is extracted using an absorption heat pump, and circulates in a closed loop.
