Honestly, UDHC is going to see continued growth because of the more traditional project backlog being developed apart from their "green" project endeavors.
The more conventional projects by JNS, such as the controls upgrade project at the hospital just recently announced, is the more stable, high revenue producing backlog that will lead to future project development.
The electric charging stations could be a flash in the pan moment right now, but if no one ends up buying electric cars, 350Green will go the way of Solyndra. Hopefully it proves successful, but if not, then UDHC can fall back on the conventional projects, and stable revenue.
Build the stable revenue backlog, and then pursue all the green initiatives you want. I bought back into UDHC primarily because of the former, not the latter.
Daily fad "green" companies are for scam pink stocks. Real companies have real projects with tried and true technologies. UDHC has their hand in both realms, and it appears to be working very well at the moment.
