The Mediterranean Investment Facility (MIF) is an initiative led by the UN Environment Programme with financial backing from the Italian Ministry for Environment Land and Sea. MIF helps establish innovative financing mechanisms to support renewable energy and energy efficiency systems as well as allow end-users to invest in renewable energies. MIF works in concert with electricity utilities, policy makers, technology suppliers, installers and local banks.

The MIF is working in Tunisia, Egypt, the Former Yugoslav Republic of Macedonia, Montenegro and Morocco. Within the MIF, the PROSOL programme has helped more than 165,000 Tunisian households purchase solar water heaters, and in Tunisia and Egypt, 61 hotels have installed them. Other technologies are also promoted, such as solar photovoltaic cells installed in about 2,000 households in Tunisia, or the 10 million efficient lamps to be installed by the end of 2013 in Morocco.
