I need to decide what is the university that is the most successful and popular in research on the energy field.
I don't know what objective criteria you could use to decide which institution is the 'most successful' or 'most popular' in a given field, especially one as broad as 'energy'. 'Energy' means different things to different people: nuclear, solar, wind, wave, tidal, conventional, etc. Are we talking number of patents awarded, amount of grant research money won, favorite team mascot, what?
I will then major in mechanical engineering there and apply for an energy- related job.
Whew! If only life were that simple.
Look, you might deign to go to university X to major in ME, but that doesn't mean you will be showered with garlands and brought to campus in a limousine. You will be competing to earn an admission slot with possibly thousands of other applicants, all who have a similar desire to attend the U of X, but maybe not major in ME like you. Universities use a lot of different criteria these days to shape the membership of the next incoming class of undergrads: it's no longer sufficient to get good grades and test scores and file your application forms before the deadline.
When I applied for admission to college, one of the schools on my list (yes, list. You should apply to several different schools in case the one you desire, for some inexplicable reason, declines to offer you admission), UC Berkeley, sent me a polite letter informing me that they were full up and wouldn't be considering any other applicants for admission for some unspecified amount of time. I didn't mind this so much, since UC Berkeley wasn't my first choice anyway. But, if I had my heart set on going only to UCB, I wonder how long I would have waited for them to tell me a slot had opened up?
