Many homes in Cuba depend on bottled gas because they are not connected to municipal gas lines. Electric stoves and hotplates are relatively rare and expensive to use due to high electricity prices.
The government said in an announcement on state media that a Trump administration sanction announced in November against Cuban state energy company Corporación Panamericana had forced the cancellation of planned purchases of liquid petroleum gas.
“Current inventories don't cover consumption, affecting the sale of subsidized and free-market LPG, which can only be guaranteed for locations that provide basic services to the population," the announcement read. “The people should adopt measures to save gas and use it efficiently.”
The Trump administration has been regularly tightening the trade embargo on Cuba with the stated aim of pressuring the country to give up its close relationship with Venezuelan President Nicolás Maduro, whom the U.S. wants out of office.
The U.S. last week banned charter flights from the U.S. to cities outside Havana, the latest pressure meant to cut off the flow of hard currency and energy to Cuba.
