Energy Requirement
Definition
Energy Requirement is the total amount of Energy (per different Energy Type) that is required by an organization or sector to perform its activities, e.g., produce a certain product.
In the context of Life Cycle Assessment (or Cumulative Energy Requirement, CER) it is the sum of the total Primary Energy required for production (CERP), the total energy for using a product (CERU), and the energy required for disposal (CERD) over the entire lifetime of the product.
Energy managers coordinate the energy use in an organisation, and aim to implement policies for increased sustainability, and minimisation of cost and environmental impact. They monitor the energy demands and use, and develop improvement strategies, as well as researching the most beneficial source of energy for the organisation's needs.
