Developmentgeothermal is a field focused on identifying, assessing, and commercializing geothermal resources for electricity and direct-use heating and cooling. It encompasses exploration, resource characterization, technology selection, permitting, finance, construction, operation, and repurposing of geothermal wells and facilities.

Resource development begins with geological, geophysical, and geochemical surveys to estimate resource temperature, flow rates, and sustainability. Exploration drilling confirms reservoirs and assesses risks. Permitting involves environmental impact assessment, land use, and water rights. Drilling targets wells to supply the plant.

Geothermal power technologies include conventional hydrothermal plants using steam or hot water, dry steam, flash-steam cycles, binary-cycle plants, and enhanced geothermal systems that enable resource development in less-ideal reservoirs. Direct-use applications use lower-temperature water for space heating, aquaculture, and industrial processes.

Environmental considerations include land disturbance, water usage, subsidence risks, and potential induced seismicity. Emissions are typically low, but surface deployments require careful management of brine, scaling, and mineral deposition. Reservoir stewardship aims to sustain long-term output.

Economics depend on resource quality, drilling costs, plant efficiency, and policy support. Projects rely on long-term power purchase agreements, tax incentives, and grid interconnection. Risks include resource depletion and technology performance, which can be mitigated with reservoir management and modular development.

Globally, geothermal development concentrates in tectonically active regions such as North America, East Africa, and the Pacific Ring of Fire. Ongoing research seeks lower-cost drilling, higher-temperature binary and EGS, and integration with energy storage and smart grids.
