Starting point The development of an energy policy is the starting point for an effective energy management. Although some companies may already have taken action to reduce their energy bill, few have recognised the need to formalise this in a structured way. This starts with an energy policy. www.engine-sme.eu
Formalised approach 1. Discuss the strengths and weakness of the energy system of the company, 2. Realise the interdependencies of individual departments, 3. Discuss possible future developments 4. Be aware of the strong dependency on fossil fuels and external suppliers. www.engine-sme.eu
