The classic and proven successful way to provide energy-focused consulting is to follow a "structured" process, which combines technical, financial, legal, and management topics:
(1) Gather information on current and future energy use and costs,
(2) Analyze it,
(3) Create alternatives to reduce costs and/or improve energy reliability,
(4) Decision-making, and
(5) Implementation.
For upper managers of companies or institutions already familiar with energy, there is an alternative worth considering, as it speeds up and reduces consulting costs. This involves exploring "just what's missing."
It results in a simpler, more direct approach that requires much less time for both the client and the consultant. For anyone who wishes to explore this alternative, let me assure you that in my consulting experience it provided great results!
