Thank you 
Itās a lot of hard work, but it varies a lot, sometimes itās āsuit & tieā conference day, sometimes itās lab work. Right now I have blue spots of tracer dye on my hands and Iāve spent the last couple of days inhaling ammonia vapor, next to a compressor.
Thereās a lot of amazing people around here, Iām definitely not alone 
If you want to do cool research stuff my best suggestion for you right now is:
Focus on getting as much of your outside experience from machine learning into your studies as an energy engineer.
An example of this could be writing an assignment/project/thesis on optimizing a cityās energy distribution control by leveraging house-batteries as the reservoir network.
