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
Net energy gain of gasoline, and the combustion of coal is converted from thermal to mechanical, and then to electrical energy. Examples of energy sources include: The term net energy gain can be used in slightly different ways: The usual definition of net energy gain compares the energy required to extract energy (that is, to find it, remove it from the ground, refine it, and ship it to the energy user) with the amount of energy produced and transmitted to a user from some (typically underground) energy resource. To better understand this, assume an economy has a certain amount of finite oil reserves
