Hilo gas prices continue to fall

[MarkP]

Raw efficiency is not the only consideration. Every time you gas up fumes leak into the air. Usually, you drip some on the ground as well. It may not seem like a lot but multiply it by the millions of cars that fill up daily. Also factor in millions of poorly tuned and maintained ICE cars. Say what you will about HELCOs motives but they are forced to run their plants relatively cleanly. Gas stations also leak and pollute the ground water.
