The purpose of this legislation is to update and improve the Geothermal Steam Act of 1970 to encourage faster exploration of geothermal resources on federal lands. The goal is to make it easier for companies to explore and develop geothermal energy, which is a renewable energy source derived from the heat of the Earth. Key provisions of the law include defining what constitutes a geothermal exploration project, which involves drilling specific types of wells and ensuring minimal environmental impact.
