The range of geothermal resources that exist worldwide provides the opportunity for countries to leverage the resources available and apply them at a large or small scale. From direct use, to electricity generation, to heating and cooling, geothermal sources can meet a host of energy needs through a renewable resource. Geothermal energy is an underused heat and power resource that provides a reliable, low greenhouse gas alternative to conventional sources. Countries have employed an array of mandates, incentives and deployment programs to promote the use of geothermal power sources. This page provides access to technical resources that policymakers can use to inform the design and implementation of policies and programs to advance deployment of geothermal technologies.
