Energy access Across the globe, many households do not have access to electricity.
Islands and isolated grids Remoteness, climate conditions and physical constraints exclude the possibility of grid interconnection.
Clean energy mix The increasing scarcity and soaring costs of fossil fuels promote sustainable development and the diversification of energy production modes.
Electricity supply security With the expansion of the interconnected network, local energy autonomy provides security for the electricity supply to end-of-grid regions.
Example: Ushant and Molène Islands
Some of the Ponant Islands, along France’s western coast, have an energy problem due to their insularity as they are not or cannot be connected to the intercontinental grid. This is the case for Ushant and Molène, which are equipped with generator sets to supply them with electricity.
Over and above the pollution generated by this high-carbon power source in particularly fragile micro-environments in need of safeguarding, this solution involves production costs around 4 times higher than in mainland France. In the case of the two above-mentioned islands, the need for electricity leads to the annual consumption of 2.3 million litres of fuel oil.
As these islands are located in areas of high hydrokinetic activity, the installation of tidal turbine infrastructures would significantly reduce the carbon dependence of their energy production.
Example: Canada’s Far North
Electricity production in Quebec is atypical as the vast majority relies on renewable sources, of which hydroelectricity accounts for 97%.
Furthermore, the population density of Quebec is characterised by its heterogeneity (mainly concentrated along the US border). Nevertheless, a few Inuit populations are found 1500 km away in the Far North (Labrador and Nunavik) and cannot be connected to the province’s electricity grid due to climate conditions.
These communities’ energy need is satisfied once again by thermogenerators, for which a tanker of fuel oil is sent biannually.
In a particularly virtuous provincial context in terms of energy production, Prime Minister Jean Charest implemented a development plan for northern Quebec with a substantial section on renewable energies. The winter conditions make it difficult for wind and solar energy production to be efficient.
Yet these distant regions enjoy mountainous terrain and a hydrographic network generating torrential rivers conducive to the installation of turbines.
