Energy Engineering or Mechanical Engineering, which one should I choose?

[surya2095]

I am in the fianl year of my bachelors degree in Mechanical Engineering. Having done two projects in the field of energy conversion and waste energy conservation, I was thinking of choosing Energy Engineering for my Masters degree. But my seniors are suggesting that Energy is not a good field and so go with mechanical engineering for masters and then narrow it down to energy in the PhD level. I am confused. Which one is better? Can someone help me out
