Dennis’s Answer

Rana, I would echo the comments made by Melody and Rohit. I have a degrees in Mechanical Engineering, but have not heard (specifically) the term "power" used in that context. I'll make a couple of guesses. 1) It could be in the field of Power generation for electrical or other systems. If that is the case, you might be dealing with engines and how they interface with machinery to produce electricity or otherwise convert fuel energy into a different useful form; or, as in a base power plant, it could be a fossil fueled steam plant; it could be a nuclear fueled steam plant; another possibility is in solar or wind power conversion; 2) it can refer to activities related to powering mobile machinery or vehicles of any type. e.g. mining equipment, commercial trucks, automobiles, motorcycles, ski mobiles, and so on. In that case, you would be dealing with the interaction between the machine or vehicle and the "prime mover", i.e. the motor or engine that provides the mechanical effort to propel the machine. Or, you might deal with other parts of the power train - the transmission, the axles, the cooling systems or whatever. In the current environment, many vehicles are now powered with batteries and electric motors. Also part of 'power' engineering.
The various disciplines of mechanical engineering come into play within any of these scenarios: thermodynamics, heat transfer, fluid mechanics, dynamics, stress analysis and even system control. So, you can get involved in "power" engineering in any number of ways.
As long as humans continue to rely on machines and vehicles to do their daily activities, we will have secure jobs as either "mechanical" or "power" engineers. Good luck to you!

Dennis recommends the following next steps:

Find engineers in your area and find out what they are doing. If possible, do a "shadowing" exercise where you spend a day or so following one or more engineers during their typical work day.

Rohit’s Answer

Mechanical engineers design power-producing machines, such as electric generators, internal combustion engines, and steam and gas turbines, as well as power-using machines, such as refrigeration and air-conditioning systems. Mechanical engineers design other machines inside buildings, such as elevators and escalators

Melody’s Answer

"Mechanical engineering" is considered the "liberal arts of engineering" meaning that you can go into any field once you receive a degree in it. It can range anywhere from the design of biomedical devices to manufacturing commercial vehicles!

HOWEVER, "mechanical POWER engineering" would have to be considered separately. I don't know the answer to your question personally but I just wanted to clarify so you didn't get confused between the two. Mechanical power engineering will be much much more specific to a certain industry. It will probably pertain to the examples given by Rohit above.
