What are the problems with the worlds oil supply?

The world's oil supply faces several challenges, including geopolitical tensions that can disrupt production and distribution, fluctuating demand due to economic shifts and the transition to renewable energy sources, and environmental concerns leading to stricter regulations. Additionally, many oil reserves are located in politically unstable regions, increasing the risk of supply interruptions. Aging infrastructure and the depletion of easily accessible reserves also pose significant long-term challenges to maintaining a stable oil supply.
