Electricity from geothermal energy had a modest start
in 1904 at Larderello in the Tuscany region of northwestern Italy with an experimental 10 kW-generator. Today, this form of renewable energy has grown to 8771 MW in 25 countries producing an estimated 54,793 GWh/yr. These “earth-heat”
units operate with an average capacity factor of 71%; though, many are “on-line” over 95% of the time, providing almost continuous base-load power. This electricity production i... [More]

This paper provides a general background on utility-scale geothermal power and seeks to teach the readers a basic understanding of geothermal power, as well as build a solid
foundation for further understanding of the technical, economic, and policy dimensions of geothermal power worldwide. Economic data and current U.S. geothermal policy help illustrate the concepts of this paper. Readers may refer to the extensive references to reports and Web links to well-established geothermal energy s... [More]

| Geothermal energy is a major resource and potential source of low emissions renewable energy suitable for base-load electricity generation and direct-use applications. Australia has significant potential geothermal resources associated with buried high heat-producing granites and lower temperature geothermal resources associated with naturally-circulating waters in aquifers deep in sedimentary basins. Most current geothermal projects in Australia are still at proof-of-concept or early commercial... [More]
