Industrial and commercial companies are facing increasing pressure to manage their energy consumption sustainably while also controlling costs. This has led to executives making long-term commitments to energy-saving measures, but procurement and operations executives must justify the cost and feasibility of these measures. Energy service companies and energy suppliers can provide solutions under business models such as energy-as-a-service (EaaS). In a recent survey, 87% of energy executives rated sustainability as a high or very high concern for their company, stimulated by stakeholder pressure, employees, investors, and customers. In response, organizations are launching ambitious sustainability goals and commitments, along with considering investment decisions such as distributed generation assets.
