The need to find new applications for renewable energy technology has grown as a result of the depletion of fossil resources and rising energy demand. In the Indian HVAC business, geothermal heating and cooling represents a recent development. Heat pump systems are used to utilize the heat from the ground to heat and cool areas, resulting in a 51% reduction in HVAC electricity consumption and a decrease in CO2 emissions. Lower operating costs and longer equipment life are geothermal energy's primary future hopes. Recent developments in geothermal heating and cooling systems are reviewed in this article.
