Five years ago EVs were a 4% footnote. In 2025 they are a quarter of every new car sold worldwide. The curve bends sharply after 2020 and never flattens, a market crossing from early adopters to mainstream in a single half-decade.
Hace cinco años los eléctricos eran un 4% marginal. En 2025 son una cuarta parte de cada auto nuevo vendido. La curva se dispara después de 2020 y no se aplana: un mercado que pasó de pioneros a corriente principal en media década.
Annual EV sales jumped from 3 million to 20 million in five years, adding roughly a Norway-sized fleet every year. The pace is not slowing: each year since 2021 added about 3.5 million more electric cars than the year before.
Las ventas anuales saltaron de 3 a 20 millones en cinco años, sumando una flota del tamaño de Noruega cada año. El ritmo no afloja: desde 2021 cada año sumó unos 3,5 millones más que el anterior.
China alone bought 66% of the world's EVs in 2025. The US, despite being the world's largest economy, took just 7%.
China sola compró el 66% de los eléctricos del mundo en 2025. EE. UU., la mayor economía, se llevó apenas el 7%.
Walk into a Norwegian dealership and 97 of every 100 new cars are electric. In a US one, only 10. The same year, the same product, four very different national stories, set by policy, grid, and incentives.
En una concesionaria noruega, 97 de cada 100 autos nuevos son eléctricos. En una de EE. UU., solo 10. El mismo año, el mismo producto, cuatro historias nacionales muy distintas, definidas por política, red e incentivos.
Across its full life, an EV on Europe's grid emits 63 g CO2/km, 73% less than the 233 g of a gasoline car.
En toda su vida, un eléctrico en la red europea emite 63 g CO2/km, un 73% menos que los 233 g de uno a gasolina.
Even with a Chinese-made battery driven on Poland's coal grid, an EV still cuts lifetime CO2 by 37%. Transport & Environment's worst plausible scenario still loses to gasoline; the best case erases 83% of emissions.
Incluso con batería china y red polaca a carbón, el eléctrico aún recorta el CO2 de por vida en un 37%. El peor escenario plausible de T&E aún le gana a la gasolina; el mejor borra el 83% de emisiones.
Hybrids cut CO2 by just 21-26%. Full EVs cut it by 67-83%, roughly three times as much.

Each kWh of battery costs 41-89 kg of CO2 today. By 2050 that footprint is projected to fall by roughly half. NMC811 packs sit at a median of 74 kg/kWh; cheaper LFP chemistry already lands lower at 62 kg/kWh.
Cada kWh de batería cuesta 41-89 kg de CO2 hoy. Para 2050 se proyecta caer a aproximadamente la mitad. Las celdas NMC811 promedian 74 kg/kWh; las LFP, más baratas, ya están en 62 kg/kWh.
In a US cell-making study, raw materials caused 93 of every 100 units of environmental harm, dwarfing factory energy.
En un estudio de celdas en EE. UU., las materias primas causaron 93 de cada 100 unidades de daño, muy por encima de la energía de fábrica.
Norway has been near 100% renewable for 15 years; the US, China and India remain under one-third. Same EV, very different footprint. Europe is decarbonizing fast (Germany 17 -> 59%, UK 7 -> 51%) while emerging giants lag, defining where EVs deliver their full promise.
Noruega lleva 15 años cerca del 100% renovable; EE. UU., China e India siguen bajo un tercio. Mismo auto, huellas muy distintas. Europa descarboniza rápido (Alemania 17 -> 59%, Reino Unido 7 -> 51%) mientras los gigantes emergentes se rezagan.
In 2018, 77% of Poland's electricity came from coal, the case where an EV may be no cleaner than gasoline.
El eléctrico promedio se vendió en $58,124 en septiembre de 2025, unos $8,044 por encima del promedio de $50,080.
Only 44% of EVs beat a comparable gas car on 5-year cost in 2025, down from 49% in 2024. Maintenance is the bright spot, $1,000-$2,000 over five years, but higher sticker and depreciation are pulling parity backwards.
Solo el 44% de los eléctricos le ganaron a un auto a gasolina comparable en 5 años en 2025, frente a 49% en 2024. El mantenimiento es la mejor noticia, $1,000-$2,000 en cinco años, pero el precio inicial y la depreciación frenan la paridad.
Upper-income Americans own EVs at 14%, more than triple the 4.4% national average; half of all EV owners come from high-income homes.
Los estadounidenses de ingresos altos tienen EVs al 14%, más del triple del 4.4% nacional; la mitad de los dueños viene de hogares ricos.
About 8 of every 10 dollars in US EV tax credits ever issued landed in the top income quintile. The bottom three quintiles combined got just 10%, the most extreme skew of any US clean-energy subsidy on record.
Cerca de 8 de cada 10 dólares en créditos fiscales para eléctricos terminaron en el quintil de mayores ingresos. Los tres quintiles inferiores juntos recibieron solo el 10%, el sesgo más extremo entre los subsidios verdes de EE. UU.
Norwegians earn 32x what Indians earn AND plug into a 99% clean grid. The richest grids are also the greenest. Income and grid greenness move together, so the EV revolution lands hardest where its environmental edge is already largest.
Los noruegos ganan 32 veces lo que los indios y se conectan a una red 99% limpia. Las redes más ricas son también las más verdes. Ingresos y red verde se mueven juntos, así que la revolución eléctrica aterriza más fuerte donde su ventaja ambiental ya es mayor.
The research behind this deck
EVs went from niche to one in four new cars in five years, and over a lifetime they beat gasoline almost everywhere. But the green payoff and the price tag still depend on which grid you plug into and which income bracket you live in.
Poland's grid in 2018 ran on about 77% coal (hard coal plus lignite), making EVs charged there likely no cleaner than gasoline cars. MDPI (Materials journal)
