What is an appropriate school?

Hey Sergiy - You have a lot of interesting stuff in your profile and the adcoms at the best schools don't get huge numbers of candidates from the Ukraine, so you're at an advantage based on that. Plus your academics are very strong.

The risks and challenges though are:
a) not quite following your history so thought you must be quite young, if you graduated - how do you have so much work experience if you only got out of school 2 years ago? It's calculated as full-time work experience, internships don't count in this number. Maybe we just don't understand your background. The average is 5 years of work experience at many bschools so if you've got much less than that, it can be a disadvantage in the apps - you would just need to show why now is the right time.
b) your career goals need some help, they're a bit vague and quite ambitious - this will be important at many schools
c) very important is the GMAT score - the overall score of 660 is below average of any top school and the verbal score is very low. Many adcoms will have trouble with this, given how important communication (and English language) skills are in an American program.

But to get to your question: There are a variety of schools with a concentration in the energy field, each is quite different and many focus in different areas. Ones you might want to consider would be schools like UT-Austin, Rice, maybe Duke for traditional oil and gas, or for cleantech/alternative energy, Ross and Berkeley are both leaders, MIT too. There's some others too but those are a good starting point.

Let us know if you have other questions we can help with. You've got some good stuff going on and your application would likely be well received with the right positioning - but you do need to look at that GMAT score as it might prove to be an obstacle. (You may also need the TOEFL too - we assume that Kiev Polytech curriculum is not in English.)
