The project aims to participate to the objective of 15% RES in 2010 in the energy balance of the Great Lyon. REStart concerns :
Energy efficiency and renewable energy program in the building sector;
Photovoltaic installation;
Building sector.
At urban scale, the objectives are:-
To decrease energy consumption of new buildings with low environmental impact
To decrease or even eliminate the over-cost of RES with efficient techniques for building
RESTART project concerns 200 dwellings in the social housing sector in 7 independent projects in social housing sector.

Among the renewable energy sources, hydropower is the one that is used most. In some European countries, it covers more than 30% of the national electricity needs. New, big hydropower stations will be required because of the damming up of rivers and the related environmental laws only very rarely be constructed. But there is a big potential for the mini-hydropower below 1 MW. It can be very cheaply (re)activated in those places where there are still old exploitation rights and where old installations can be reactivated in the case where dams exist. In the city of Megève, in the French Alps, since 1968 one mini hydro power system was installed in the drinking water system, this supplied the municipal sports hall with electricity. Hydropower on water system is hardly developed in France. In the absence of incentive policy on the matter, only a few facilities on the irrigation and on the drinking water systems have been carried out. Most of the time, these facilities have been developed as people became more aware of the aspects linked to the energy promotion and to benefits and/or economies that may result from those different facilities.
It was during the 60’s that the idea of promoting drinking water collected and stocked in the reservoir of the Livraz, on the plateau of the Mount Arbois, 300 m above Megève, first
appeared. Plan and action followed. When the Sports and Conference Centre opened in 1968, the hydro-electric plant (Pelton turbine and asynchronous generator of 300 kW) worked in a semi-automatic and discontinuous way, with heavy human constraint.
