Hubbert's Peak is a theory proposed by geologist M. King Hubbert in 1956, which predicts the point at which the production of a resource, such as oil, reaches its maximum level before declining. This concept is based on the idea that resources are finite and that extraction rates will follow a bell-shaped curve over time. After reaching the peak, production will gradually decrease as the resource becomes more difficult and expensive to extract. This theory has significant implications for energy policy and economic planning, as it highlights the potential challenges of relying on non-renewable resources like fossil fuels.
