The renewable energy will play significant role in the world primary energy consumption in the future.Geothermal energy is immense with 5 000 EJ/a of technical potential,and geothermal heat pumps(GHPs)are one of the fastest growing applications of renewable energy in the world with annual increases of 10 % and much faster in China.With high coefficient of performance(COP)up to 6,GHPs make efficiency of primary energy more than 240 % with assumed a 40 % of electricity generation efficiency,which means energy savings and CO2 emission reduction.In this paper,the geothermal resources and its utilization are talked about,and GHPs technology was introduced.Due to its high efficiency,there will be energy savings by using GHPs.There is also CO2 emission reduction because of using geothermal heat pumps,which is analyzed in the end.
