(NB. In each case, company and role is correct at the time training was provided)

I attended the “Mastering Renewable & Alternative Energies” course taught by John and it was the most comprehensive training that I had in renewable energy. It covered all broad aspects of renewable energy and had sessions of in-depth technical and financial analysis on wind and solar energy. John has deep expertise in the renewable energy sector and is up-to-date on the current market trends. He has a natural ability to explain complex terms and break them into comprehensive bits for understanding. I would recommend my colleagues to his future courses.

I had the privilege of taking John’s 5-day training course on renewables. I can easily say that it was the best investment i ever made for my professional development. The course was very holistic – it covered technical aspects of all renewables technologies and also delved into financials and economics of renewables. John has solid grasp not just over different aspects of renewables industry, but also over different segments of the energy & power industry. I felt that the knowledge was imparted in a very methodical and logical manner which made the learning even more enjoyable and immersive. John is also a wonderful communicator and has the ability to translate the most complex technical matters into simplest of words. The course and training was a good mix of theory and practical hands-on experience. For me the most enjoyable portion of the course was the LCOE model that explained how the economics and all the technical parameters of renewable technologies fit together – that LCOE tool proved to be extremely useful for my latter work experience. I also enjoyed the energy modeling exercise where we had to develop the right energy mix for a country. Overall, the 5-day course offered by John was totally worth it. I highly recommend the renewable energy courses/workshops offered by John to anyone who is interested in learning more about any aspect of renewables/clean energy.

I have now taken 2 courses taught by John (Renewables Mini-MBA and Storage). I not only would recommend him without reservations, but I have also been sending my team to his courses. He combines detailed technical expertise with deep knowledge of the (complex) energy markets, also bringing it all together in the context of each relevant regulation and the economic business cases underlying investment decisions. I have enjoyed his courses – and have learnt a lot from them.

I recently finished a 1 week training on Renewable Energy with John as the instructor. I thoroughly enjoyed the course. John is a very good instructor and makes the sessions very interactive also pooling in the significant experience of others in the sessions. He is very knowledgable on all aspects of the topic including recent developments and enables his trainees to make critical connections between different aspects. I would highly recommend him.

Having worked as a co-presenter with John on a number of occasions, I wouldn’t hesitate to recommend him to any organisation seeking a clear, well-informed and independent perspective on renewable energy. His relaxed style encourages questions and engagement from his audiences and he’s particularly skilled at bridging the language gaps between technological/deployment, market/policy and economic/investment issues.

Charley Rattan, Senior Project Manager, Community Windpower Ltd.


I attended one of John’s courses. He was personable and very thorough and the course was well researched, interesting and on point. John managed to include attendees from many different parts of the industry from many countries and pack a lot of information into 5 days and incorporated a fascinating group exercise/presentation project on the last day. Highly recommended for anyone looking to gain knowledge in Renewable Energy.

Having attended a 5-day seminar led by John Massey covering the field of renewable energy from an investment-, technology- and political angle; I can say that John Massey is a source of inspiration. He stands out with his capabilities as instructor fuelling discussions as well as having a broad knowledge base of his own.

I participated on one of John’s courses in renewable energy. This was one of my best spent weeks on training all year! A good and efficient way of getting an overview of the renewable energy sector. I found John very knowledgeable and enthusiastic in presenting the material, also enabling knowledge exchange between participants in the group. I really enjoyed his interesting lessons and the group work he provided for additional learning outcome. Thanks John!

John has in-depth knowledge in the renewable energy sector. I found him to be very effective in highlighting the decisions that come into play in creating an energy strategy. Through sharing of unbiased analysis, highlighting technology pros and cons as well as the associated industry challenges he demonstrates a thorough understanding of the intricacies of renewable energy business that is an extremely valuable resource to his clients.

Brenden Marchewka, Project Development - Major Projects - Power/Renewables, Enbridge


John represents a thoughtful and unbiased view in the realm of renewable energy. His insights are well reasoned, clear and, perhaps most importantly, backed up by hard numbers. Definitely a person I would turn to for guidance in this space.

Excellent overview of renewables in the context of overall energy mix, and also details on specific renewable markets and technologies. Highly accomplished trainer with a broad knowledge and the right mix between slides and exercises.

I had the pleasure of working with John for a number of years and can genuinely say he’s one of the most professional and knowledgeable people I know. His ability to analyse extremely complex information and ensure people at any level, from entry-level, to board-level, can understand and use that information is second to none. I wouldn’t hesitate to recommend John to anybody who is looking for the best of the best in energy analysis, training or advice.
