One never knows how their culture will change.  On the East Coast, home heating oil USTs became a nightmare:  A National Nightmare in the 90's.   Though in the 40's to 50's this was what everyone did.  They dug a hole, but in a tank, and ran an oil furnace.   Then, oil got expensive, and people switched over to Natural Gas - the new clean energy.  And all those old tanks had to be decommissioned.  Which was also expensive.   So after that conversion, we now have a new conversion and natural gas is now the evil heating source, rather expensive, and we should all switch to electric.  There is a pattern here.
