Energy Wisdom Programme

Energy Wisdom Programme, is a voluntary electricity industry initiative on sustainable development launched by EURELECTRIC in the year 2000. It provides a platform upon which electricity companies are able to demonstrate their proactive approach towards sustainable energy production, delivery and use. Their main objectives are to achieve measurable improvements in energy efficiency and reductions in greenhouse gas emissions in a cost-effective way.

EWP considers the following categories: electricity generation, electricity transmission and distribution, end-use energy efficiency, carbon sinks and other.

ENDESA joined this initiative due to the importance they give to environmental protection, sustainable development and transparency, and because this initiative gives the company an opportunity to show their commitments and efforts to contribute to a sustainable energy development.
