A single exploratory ocean oil well costs as much as a Mars rover with design, launch and operations. There are thousands of them. We owe our modern world to O&G, but by now they could be producing oil & gas from CO2 -> Methane using solar / wind (/ nuclear?) and the CO2 in the air around us. The infrastructure to do so sounds enormous, but we gloss over all the diplomacy, wars, foreign & domestic wells, tankers, refineries, ports, trucks, pipes, gas stations, etc etc we had to build in the last 100 years to actually make O&G the everyday industry it is. How many trillions? The ROI was totally worth it, but maybe it's time for more I and less R. It's not that the industry or even oil itself is evil, it's that we can do better.
