Help me to choose graduate program. Major concern is Energy.

[Maheen]

I need some suggestions. Please folks help me. I am a petroleum engineeing graduate. Due to the current downturn and volatility of job security, I want to switch to another major for graduate study. Would you please help me to choose from the following option.? 1) Energy Related programmes, like Energy Engineering, Energy Technology Where the efficiency and optimization would be major concern (correct me if I am wrong). Can you please tell me anything about the job scenario of energy engineer or energy technologist? What are their major role in industry? Efficiency only? 2) Energy management, Energy Economics. . It's like MBA or MA. However as long as the things are energy related so it would be okay. But this programmes require job experience which I don't have right now. 3) Sustainable Energy. It's completely renewable sector. So would I be able to cope with it with my specified petroleum engineering background? 4) As petroleum engineering is most of about computational technology, so I have extensive knowledge on computational programming languages. I am a problem solver with huge volume of Data. Digitalization is the future of oil & gas and Data Science is the pioneer of this digitalization. So what about pursuing Data Science as graduate study? Data science knowledge would be useful for any kind industry. So I wouldn't have to worry about the ups & downs of industries. Moreover, please tell me the name of any middle rank university of US and Canada, who offers masters degree on above mentioned programmes. Then, what are the chances of a petroleum graduate will achieve a graduate funding in the energy related masters study? Have you know anyone who had petroleum major in undergraduate but switched to another major related to energy or other concern with full funding? Have anyone switched to renewable graduate study having petroleum background? I would like to get the research assistant type position so that I wouldn't have to worry about financial issues. I am comfortable with research works. Please share your experience. Moreover, if you can guide me to any other sources where i will find the answer of my all or some queries above i mentioned, i will be really grateful to you. Thanks for reading the long text.
