Hydrothermal Reserves Geothermal energy is found in many places on the earth. Its use contributes to the development of important third-world countries including the Philippines, Indonesia, Mexico, countries of Central and South America, and countries in eastern Africa and in eastern Europe. Italy, Iceland, New Zealand, Japan and France, along with the United States, are developed countries using geothermal energy. There is a very large geothermal resource base in the U.S. and in the world, much of which can not yet be economically used. Flexibility and Reliability Systems for use of geothermal energy have proven to be extremely reliable and flexible.
Geothermal plants are modular, and can be installed in increments as needed.
Both baseline and peaking power can be generated. Construction time can be as little as 6 months for plants in the range 0.5 to 10 MWe and as little as 2 years for clusters of plants totalling 250 MWe or more.
