The document provides an overview of a recent IEA RETD Financing Study and highlights the importance of smart grids for energy infrastructure. It summarizes the study's findings that existing finance mechanisms alone will not attract the large quantities of new investment needed for renewable energy and that new approaches are required to reduce risks and show potential profits to investors. It also outlines the IEA RETD smart grid roadmap project which models an increasing share of renewable electricity in Ireland through 2050 with significant cost savings, and identifies key actions over the next 10 years such as establishing smart grid test facilities and developing interoperability standards.
