A geothermal energy system with reverse thermodynamic flow scheme that employs a pump or a compressor in series with a ground heat rejection or a ground heat absorber. The pumped geothermal energy system evaporates and condenses the working fluid at substantially the same pressure in the ground loop. The working fluid could be carbon dioxide, Freon, water or any other suitable refrigerant. The compressive geothermal system condenses the working from a vapor to a liquid above, below, and substantially equal to critical pressure using carbon dioxide as the working fluid.
