Is OPEC very influential in the world?

Yes, OPEC (Organization of the Petroleum Exporting Countries) wields significant influence in the global oil market due to its ability to set production levels and influence oil prices. As a coalition of major oil-producing nations, OPEC can stabilize or destabilize markets by coordinating output among its members. Its decisions can impact economies worldwide, particularly those heavily reliant on oil imports or exports. However, the rise of alternative energy sources and non-OPEC oil production has somewhat diminished its influence in recent years.
