Renewable energy in Albania take part in choosing location including: altitude, site accessibility, infrastructures, protected areas, and power grid. The wind speed is 8–9 m/s in many areas of Albania. Albania might export excess wind energy to Italy. Geothermal energy could also be used in Albania. It comes from warm water sources from underground soil. Geothermal energy comes from the heat generated by the Earth. There are some spots called hot spots that generate more heat than others. There are natural wells near Albania’s border with Greece. This energy could be used for heating purposes. Geothermal energy in Albania is under study and there
Underground mining (soft rock) depending on context). Underground mining (soft rock) Underground soft rock mining is a group of underground mining techniques used to extract coal, oil shale, potash and other minerals or geological materials from sedimentary ("soft") rocks. Because deposits in sedimentary rocks are commonly layered and relatively less hard, the mining methods used differ from those used to mine deposits in igneous or metamorphic rocks ("see Underground mining (hard rock)"). Underground mining techniques also differ greatly from those of surface mining. The number sign, or hash sign (#) is often used as shorthand to denote shaft or seam, as in 4# (4
