In the search for new energy resources, scientists have discovered ways to use the Earth itself as a valuable source of power. Geothermal power plants use the Earth's natural underground heat to provide clean, renewable energy.

The geothermal energy industry has expanded rapidly in recent years as interest in renewable energy has grown. In 2011, the U.S. Bureau of Labor Statistics (BLS) counted about 1,050 jobs in geothermal power generation. And the Geothermal Energy Association estimates that there were about 5,200 jobs directly related to geothermal power production and management in the United States in 2010.

Geothermal energy production is expected to continue to grow, and with it the demand for workers in associated occupations. In 2012, the geothermal industry was developing 130 geothermal projects in 15 states, according to the association.

This article describes geothermal energy and career opportunities in the industry, focusing on geothermal projects that generate electricity for power grids.
