`hi_dmv_ev_registrations`

Pack: hi-dmv · Endpoint: https://gateway.pipeworx.io/hi-dmv/mcp

Count electric and hybrid vehicles registered in Hawaii as an annual time series from 1999 to the present, with battery-electric and hybrid vehicles counted separately plus a combined total, and the year-over-year change and growth rate for each year. Answers “how many electric vehicles are in Hawaii”, “how many EVs were registered in Hawaii in 2020”, “EV adoption trend in Hawaii”, “how fast is EV adoption growing in Hawaii”, and “how many hybrid cars are in Hawaii”. Figures are cumulative registered counts compiled statewide by Hawaii DBEDT; registration itself is administered by the four counties (Honolulu, Hawaii, Maui, Kauai), so this series is published at the state level.
