The group has helped me understand lots of Python and GAMS code for many energy topics. I have completed training in Reinforcement Learning for energy, energy geopolitics and mapping , and energy finance topics like energy derivatives. It has hundreds of Python models on these areas explained in video format . The availability of the instructor (Dr) is one of the highlights of the group . Any question I had, were answered , the same day. So overall , very satisfied with the training / support.

I give 5 stars because the online courses literally explain every line of the code they teach and anytime I have had questions these have been replied directly by Dr Spyros within a few hours. This has helped me literally understand 100% of the content of every course I have taken. Also, I have liked that the courses allow you to download all the material and they are being updated frequently with new videos/code etc. Also I have built my online project portfolio with feedback from many members.

Very positive experience. Immediately upon joining I got a personalised curriculum of 3 online courses. After completing them, I was supported to create an online project in my online portfolio (GitHub). I repeated this cycle with more courses & projects. At the same time, I got support with my job applications: my CV & Cover Letter got rephrased according to the company/role I was applying for. I was supported also with interviews. Strong group for jobs in energy and/or data science & research

🌟Dr. Spyros Giannelos is an outstanding educator who has a rare ability to make complex ideas feel clear, practical, and genuinely exciting to learn. As a student of Data Energy Scientist, I have benefited from his ongoing guidance, thoughtful support, and deep understanding of the subject.His teaching goes beyond surface-level instruction and encourages you to think critically, apply what you learn, and grow with confidence. If you are interested in Data Science, I highly recommend this Skool.

The Energy Data Scientist has sharpened how I approach commercial and industrial energy flexibility. The courses put energy modelling, Python, optimisation, and electricity market mechanics in one place. Dr. Spyros has provided personalised course recommendations and detailed feedback on my BESS optimisation tool. He helped me improve the methodology and connect the model more closely to real commercial applications.I recommend this community if you're building a quantitative career in energy.
