Hi Ayman, gem5 has some support for energy modeling for a few objects (e.g., the DRAM controller, maybe others). However, it does not have energy numbers for the CPU cores. To get CPU-core energy you would need to take the gem5 stats output, which includes functional unit activation information, and pass this into McPAT which takes the activation information and returns power/energy.
