The Jones Act was written in 1920 ^[16]. It requires every good moved by water between U.S. ports to ride a U.S.-built, U.S.-flagged, U.S.-owned, U.S.-crewed ship ^[17]. It governs all domestic waterborne trade ^[15]. The energy trade has moved around it, and the bill lands on buyers. About 500 ships on Earth can carry LNG. None of them is Jones Act-compliant ^[1]. So New England, inside a nation that exports natural gas, depends on foreign LNG ^[2]. Puerto Rico buys its LNG from Trinidad and Tobago instead of from American suppliers ^[3]. The law does not protect the domestic market. The case here, on the evidence, is that it locks American buyers out of it. The price shows at the pump and on the power bill. Fuel transport costs raise gasoline by up to 15 cents a gallon ^[11]. LNG for Puerto Rico runs up to 30% higher ^[12]. Shipping crude from Texas to East Coast refineries costs more per barrel than shipping it across the ocean ^[10], so the East Coast imports foreign oil while the Gulf sits on surplus ^[7]. Cargo goes around the wall instead of through it. The wall is expensive to build into. A tanker built in the U.S. costs about double a foreign yard ^[5]. U.S.-built oil tankers run about four times the foreign price ^[13]. If not for the Jones Act, the record says, America might cut its crude oil imports in half ^[8]. A hundred years in, that is reason enough to repeal the law and let American fuel move by American water without a surcharge on every barrel.
