It is my pleasure, as Chairman of the Organizing Committee of the 2005 World Geothermal Congress, to welcome everyone interested in the protection of our environment to this extraordinary event. Geothermal energy is a clean, green, safe and widely available source of energy. It is utilized today in hundreds of places in dozens of countries. Its use will continue to grow as the public becomes more aware of its benefits and availability. Please join us in helping the world to know about the advantages of geothermal energy: Antalya, Turkey, 24-29 April 2005.
