Watt by watt, clean cars are making their own place in the national vehicle fleet. Specifically, 561,580 cars with non-fossil engines were circulating in Spain at the end of 2019. This is one of the conclusions of an UNESPA report on the use of this type of vehicle. Provinces and cities with higher GDP usually have higher rates. The provinces with the highest rate of clean vehicles are Madrid (3.41%), Barcelona (3%), Alicante (2.71%), Gerona (2.71%) and Las Palmas (2.08%).
