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.

This is the only comprehensive energy group I could find online. The community members share downloadable resources that I have found very useful, especially the papers. Also I like the self-paced learning. The courses cover topics useful for my career. Specifically, smart grid, Machine learning for energy, Monte Carlo for energy, power system economics , optimisation, and derivatives, git/github, Claude code/codex, ML ops for energy etc. Also the instructor is a well-known authority. I give 5/5

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.
