Well, if OPEC is an oil cartel who makes money off oil, an embargo stopping the purchase of oil doesn't help.
The 1973 oil embargo initially increased revenues for OPEC by raising oil prices, but it ultimately hurt the organization by prompting increased competition from non-OPEC oil sources, encouraging internal conflicts among member countries, and leading to a shift in energy consumption patterns. These factors diminished OPEC's power and control over oil prices in the following decades.
