Reduced Expenses

Exciting to see Carnival Cruise lines switching over to LNG and or CNG/RNG as their new clean burning engine fuels. First of all, there is plenty of both here produced in the USA, the cost is 1/2 that of diesel or fuel oils per gallon equivalent, and it burns much more environmentally cleaner. Batteries need to be charged and recycled, very expensive to do. LNG & CNG appears to be the answer thinking Green.
