Portocolom is a small port on Majorca's southeast coast in Spain and the harbor is nearly enclosed by a rocky peninsula. Located at the tip of the peninsula the lighthouse in Portocolom is called Far de Sa Punta de Ses Crestes and was built in 1863 by Emili Pou. In 1918 the tower was raised 6.5m in order to reach a greater geographical range. In 1965 the signal was electrified and the height of the tower was increased again:  the current 25 m (82 ft) round cylindrical tower, painted with black and white horizontal bands and adjacent to a 2-story keeper's house. The lighthouse emits two white flashes every 10 seconds and the signal range extends to 10 nautical miles. 
Correos de España issued on February 20th, 2009 a set of four stamps called “Renewable energies” and the postcard brings the 0, 78€ stamp devoted to geothermal energy. Geothermal energy is obtained by tapping the heat of the earth, usually from kilometers deep into the Earth's crust. This energy takes the form of hot steam or hot water mixed with chemicals that come out as hot springs or geysers. The hot water or heat can arise naturally or be artificially pumped. Iceland is the main producer in Europe of geothermal energy.
