  We consider an integration of renewable energy into transport and electricity
sectors through vehicle to grid (V2G) technologies for an energy system that is
predominantly based on lignite. The national energy system of Macedonia is
modeled using EnergyPLAN which integrates energy for electricity, transport and
heat, and includes hourly fluctuations in human needs and the environment. We
show that electric-vehicles can provide the necessary storage enabling a fully
renewable energy profile for Macedonia that can match the country's growing
demand for energy. Furthermore, a large penetration of electric vehicles leads
to a dramatic reduction of 47% of small particles and other air pollutants
generated by car traffic in 2050.
