Tunisias 2008-2011 Energy Efficiency Programme tackles energy efficiency across various sectors of the economy, with the primary target of reducing national energy consumption 20% by 2011. The plan also aims to increase the share of renewable energy at a national scale, to reach 4% of primary energy supply and 10% of total electricity installed capacity by 2011. It also emphasises the need for rural electrification and renewable energy deployment in the agricultural sector. The plan promotes the development of wind energy, water pumping and desalination from solar PV and biogas production for domestic and industrial uses. To support energy subsitution, Regional Committees for Agricultural Development will replace any diesel-sourced pumping equipment by renewable energies-sourced equipment. All three sectors - water pumping and desalination, rural electrification and biogas production - are entitled to financial support for research and development, and a 40% of initial investment premium up to a maximum of DTN 20 000. Large industrial and agricultural companies producing biogas and connected to the national grid are entitled a premium of 20% of initial investment up to a maximum of DTN 100 000. Regarding financial institutions, the plan seeks to rationalise, with the National Energy Efficiency Fund (FNME), funding and premiums allocated to renewable energy projects. To boost this support capacity, the plan establishes that income derived from the Clean Development Mechanismswill be attributed to the National Fund for Energy Efficiency.
