Sustainability Written Report - Essay role modelOriginally, geothermic life force was used in hot springs as early as Paleolithic time according to a study made by Cataldi (1993) about the history of hot springs before the innovational Period. Technically, the first geothermic energy harnessed lighted a few light bulbs. The following accounts relate how the world recognized geothermic energy On July 4, 1904, Prince Piero Ginori Conti tested the worlds first geothermal generator at the Larderello dry steam field in Italy. Merely a couple of long time later, this invention was deployed commercially and used to operate drilling equipment. Soon the small town of Larderello was using geothermal power for all its electricity requirements. (History of Geothermal Energy, http//www.economywatch.com) Because of the said event, it is no wonder that Italy maintained the position as being a top producer of geothermal energy for many decades. New Zealand followed suit alone fifty-years la ter. The United States took the risk and invested in the Geysers Geothermal Field in California which is currently the largest producer of geothermal energy in the world. This location has five power plants and Chevron Corporation spearheads in providing geothermal energy to millions of American homes. Uses of Geothermal Energy Geothermal energy has many useful purposes, with electricity generation as its most widely-known use. Bioeconomicfuel.com cites the 5 different uses of geothermal energy (Stern, 2009) 1. Industrial and Agricultural Uses A good example of which is the role of geothermal energy in drying up timber. In New Zealand, the Tasman Pulp and Paper pulverization uses geothermal steam in heat exchangers to heat kiln air to 140?C for timber drying( Stewart, 2009). excursus from timber, crops can also be dehydrated using geothermal energy which makes this type of energy very(prenominal) useful for agriculture. 2. Food Processing The diet processing industry can harnes s the heat from geothermal energy for sterilization process as well as drying. In India, Chandrasekharam (2001) published a written report that advocated the use of geothermal energy in diet processing since Indias topography is viable for this type of food processing. However, the United States had already applied that concept way back in 1978 when it opened the geothermal food processing plant in Brady Hot Springs, Nevada. In fact, More than 25 million pounds of dehydrated onion plant and garlic are now being processed annually in Nevada (nrel.gov, Oct 2001). This fact just attests to the enormous capacity of geothermal energy in providing clean energy at a lesser cost. 3. electrical energy Generation The Geothermal Energy Market Report shows that in 2005 alone, the top ten countries used 97% of geothermal energy for electricity generation purpose (refer to Appendix A). According to the International Energy Agency, geothermal energy currently supplies less than 1% of the worlds total energy demand. Nevertheless, it has an enormous potential to relieve climate changes by reducing the use of carbon fossil fuels. It is a considerable source of renewable energy. In the case of Philippines, (which is second to the United States in using geothermal energy), it has a potential to stupefy one of the worlds largest producer of geothermal energy. Currently, geothermal energy supplies 27% of the countrys electricity (www.philippines. hvu.nl). During the World Geothermal Congress in 2000, it was declared that the
