Overview
Geothermal Energy covers the generation of electricity and provision of heat from the earth's subsurface heat: conventional hydrothermal plants and the emerging enhanced geothermal systems (EGS) that engineer reservoirs to vastly expand geothermal's reach. It spans geothermal operators and a wave of next-generation developers (Fervo Energy) applying oil-and-gas drilling techniques to geothermal.
Demand interest is rising sharply as geothermal offers firm, 24/7, carbon-free baseload power (increasingly attractive for data centers seeking clean firm energy), with enhanced geothermal and oilfield-services crossover unlocking new potential. It is an emerging-again, capital-intensive segment attracting venture, energy-major, and data-center interest; conventional geothermal generation is included in Power Generation.

Small, steady and structurally different from the rest of renewables: geothermal runs around the clock, so it earns firm-power pricing that intermittent generation cannot. That premium is why enhanced geothermal attracts capital far out of proportion to the segment's current size.
