Geothermal Energy

A recent article in the Washington Post, “Filipinos Draw Power from Buried Heat,” focuses on successful use of geothermal power in the Philippines:

Geothermal power now accounts for about 28 percent of the electricity generated in the Philippines. With 90 million people, about 40 percent of whom live on less than $2 a day, this country has become the world's largest consumer of electricity from geothermal sources. Billions of dollars have been saved here because of reduced need for imported oil and coal.

An article on the web site of the International Geothermal Association (“What is Geothermal Energy?”) gives a full description of geothermal energy with an emphasis on science and technology.

Interdisciplinary works on geothermal energy, and works that emphasize resource economics of geothermal energy, are classed in 333.88 Geothermal energy.  At that number is the note: “Class here electricity derived from geothermal energy, thermal waters.”  Geothermal Energy: The Reliable Renewable: Geothermal Resources Council 2004 Annual Meeting is an example of a work classed in 333.88.  Geothermal Energy Resources for Developing Countries is classed in 333.88091724 Geothermal energy for developing regions (built with 333.88 Geothermal energy plus T1—09 Geographic treatment, following the footnote instruction at 333.88 to add as instructed under 333.7-333.9 Natural resources and energy, where the add table shows that standard subdivision T1—09 is regular and does not need  an extra zero, plus T2—1724 Developing regions, following instructions at T1—093–T1—099 Treatment by specific continents, countries, localities; extraterrestrial worlds). 

Comprehensive works on engineering aspects of geothermal energy are classed in 621.44 Geothermal engineering, e.g., Geothermal Power Plants: Principles, Applications, Case Studies and Environmental Impact.
