Government investment, policy incentives, and technological advancement in geothermal energy have driven interest and investment in geothermal energy by emerging markets and developed markets.

• For instance, according to the data published by IEA in 2023, global geothermal power use surpassed 75% a significantly higher capacity factor than the solar (<30%) and wind (<15%) which are significantly less capable of providing reliable baseload power, thus rising demand for sustainable energy and investment in geothermal energy.

Restraints:

High Upfront Capital Costs and Drilling Risks restraints the market:

One of the chief constraints in geothermal energy is the high upfront capital investment, especially in exploration and drilling. The uncertainty associated with resource discovery creates significant financial risks compared to other renewables. Deep drilling employs the latest technology, which only further rises in cost, therefore making geothermal a less accessible option, particularly for small investors or for developing economies that may not have reliable access to capital, which challenges the opportunity for a growing market despite long-term cost efficiency.

• Counterbalance Statements: In addition, government subsidy programs, risk mitigation programs, and public-private partnerships are addressing these financial barriers affecting geothermal projects. Enhanced geothermal systems (EGS) and improved mapping seismically are also decreasing resource uncertainty and unsuccessful drillings, making a long-term investment in geothermal energy more compelling and financially viable.
