Even where long-term savings outweigh initial investments, end users may fail to choose energy-efficient options because of financial constraints. Projects and programmes aimed at facilitating financial support therefore play a key role in removing barriers to EE investment, in particular in developing countries.51 Energy savings resulting from EE investment by end users reduce the need for new investment in energy supply capacity. Whereas most supply-side investments would be made by a small group of actors, mainly large energy producers and distributors, the additional investment in end-use sectors will have to be made by a large number of small investors. The IEA therefore emphasizes that shifting investment from the supply side to the end user requires viable financing frameworks (IEA, 2006).
