To invest in energy tech you need to upgrade a building and then spend a tech point on purchasing an energy tech upgrade. However, if you do this in the Office Building then you will only gain this energy if you have an on-going contract negotiation. A similiar  thing applies with the Academy building, where that building will only supply energy if you have a youth prosepct in development. Lastly, the Psychology building does not have any energy tech in it.

So, the best buildings to upgrade to invest in energy tech are the Training, Stadium, Medical and Hotel. If you buy energy tech in any of these buildings you will get that energy every day regardless of what is going on in your club.

Hope that helps!
