The gas price controls in the 70s caused a shortage of natural gas for heating because drilling went down to almost zero and many houses had oil heating in 1974 when oil prices went up from $2.50 to $12.00 per barrel overnight. This caused severe stress an those with oil heating since isnulation standards were very poor in those days.
Nixon finally ended the 40 cents per million BTU interstate price control and drilling soared. The US quickly developed much more gas, backing out heating oil in those areas that had pipeline and distribution access.
Canada tried to control oil prices in the 70s by setting an artificially lower than market price for internal oil while putting an export tax on oil exported to the US to bring it up to world price. It caused great dislocation in the industry and local companies went overseas where their drilling effiorts would yield more returns.
Japan wisely adjusted itself to world oil and gas prices in the 70s and developed a strong lead in energy conservation and fuel efficient car design.
Gasoline price controls practiced by dictators in Iran, Venezuela, Nigeria, Indonesia,Saudi Arabia and other places have caused numerous problems, and discouraged conservation efforts.
