At this stage of the race toward the decarbonisation of our energy systems by 2050 we all agree that electricity is the main vector of the energy transition. The reason for that are threefold; first, wind and solar technologies have experienced a rapid cost reduction that make them competitive today; second, electricity is a high quality and versatile energy vector. Last, electrification enables the use of more efficient technologies, such as heat pumps or electric vehicles that consume one third of the corresponding legacy technologies.
Electricity can be transformed into mechanical energy, potential or thermal energy using existing conversion technologies, such as generators, pumps or electric heaters. These technologies should be sufficient to cover a large share of electricity needs that are automatically decarbonized if the supplied electricity comes from wind and solar.
