Several renewable power mixes are possible, requesting several types of renewable energies, completing each other. The geographical distribution of the means of production is optimized: more solar in the south,
where the sun is most important; more wind where the wind blows stronger. One thus takes advantage of the most interesting (and therefore economically cheaper) potential.
53%of produced energy is made of onshore wind
To determine an electric mix for 2050, it is necessary to rely on some assumptions for which there is a margin of uncertainty. Based on these forward-looking assumptions, optimization results in several different mixes. 3 scenarios are presented below in addition to the central scenario: If the cost of network development becomes binding, the electricity mix is refocusing around places of consumption.
If the social acceptability of renewables is more moderate, onshore wind is less installed for the benefit of less-visible energy, such as marine energy, offshore wind and solar on the roof.
If emerging technologies (marine energy in particular) see a strong technological progress and a significant gain on their costs, they can take a substantial place in a 100% renewable electricity mix.
If the cost of network development becomes binding the electricity mix is refocusing around places of consumption.
