The document outlines six common mistakes companies make regarding energy management and sustainability. It discusses the key drivers of energy change, risk areas, stages of the energy opportunity path, and delivery routes for energy solutions. The six mistakes are: 1) not bundling solutions, 2) not thinking laterally, 3) buying equipment solely for being eco-friendly, 4) forgetting that buildings deliver sustainability, not individual elements, 5) confusing sustainability with short-term cost savings, and 6) forgetting to recover energy at the end of the process. The document advocates working with expert partners to develop integrated, end-to-end energy performance contracts.
