It depends entirely on where the tax is applicable. If the tax is on income
and revenue (windfall profits revisited?) then it might curtail production
because of less capital to reinvest and less incentive to run at capacity.
If the tax is an excise and attached at the pump, then the industry
producers will see little impact to their revenue, but you and I will pick
up the load. That might result in a reduced demand for fuel, which might
increase availability but that cause and effect often alludes the
population.
