However, despite the need for increased industrial energy efficiency, studies indicate that cost-effective energy efficiency measures are not always implemented, resulting in an ―energy efficiency gap‖, which is explained by the existence of barriers to energy efficiency. Considering that SMEs are usually less efficient than Large Enterprises (LEs), this study based on a survey among Portuguese industrial SMEs, investigates the barriers that are inhibiting the adoption of energy efficiency measures and how they vary over firm‘s characteristics and over sector. Additionally the study points some drivers that could overcome those barriers. The results support the existence of barriers to energy efficiency in Portuguese industry, where lack of capital and other investments priorities were considered the most important ones. Furthermore it concludes that factors related with public policy could overcome those barriers, suggesting the need of public intervention to increase the levels of energy efficiency in the Portuguese industry.engSector industrial - PME - Eficiência energéticaIndústria portuguesa - Eficiência energética - BarreirasBarriersEnergy efficiencymaster thesis
