STORY: Classic Chevrolets used to provide a rhythmic heartbeat to Havana - but now many are turning to electric vehicles as Cuba faces its worst fuel shortages in years.
Fuel is scarce since the U.S. cut off oil exports from Venezuela and threatened to penalize other countries exporting fuel to the island.
U.S. President Donald Trump's administration has declared Cuba a threat to U.S. national security.
In the Alamar neighborhood, Eugenio Gainza weaves a state-run electric tricycle over the rutted roads, picking up passengers.
He says he makes around 16 trips a day, and with no fuel available, electric tricycles are the only transport keeping the area functioning.
Electric tricycles have become one of the most widely used means of transport on the streets of Havana for local routes and to aid mobility in busy areas.
Whether privately or state-run, tricycles transport passengers, light loads, and more.
Here's resident Barbaro Castaneda.
"Electric transportation has been solving the problem for a long time because, with or without fuel, it's the ideal moment (to use it) because it's new, renewable energy that's advancing in the world. Right now, it's giving us the progress and help we need. Truly. The state-run (tricycles) has one price, the private has another, but together it is what is helping the country move forward; otherwise, we would be completely paralyzed."
Washington has threatened to impose tariffs on suppliers, like Mexico, if they continue to ship fuel to the island.
Last week, the government detailed a plan to ration fuel and protect essential services.
Cuba has warned international airlines that jet fuel would no longer be available on the island from Tuesday.
