What is the Hubbert curve?
The Hubbert curve is an approximation of the production rate of a resource over time. It is a symmetric logistic distribution curve, often confused with the "normal" gaussian function. It has gained a high degree of popularity in the scientific community for predicting the depletion of various natural resources.
The Hubbert peak theory says that for any given geographical area, from an individual oil-producing region to the planet as a whole, the rate of petroleum production tends to follow a bell-shaped curve. It is one of the primary theories on peak oil.
- The world's population will exceed nine billion in 2050, with most of the growth in developing countries. The United States Department of Agriculture reckons that the number of hungry (“food insecure”) people in sub-Saharan Africa will rise by a third. The FAO reckons that food production will need to increase by 70%.
- Earth could continue to host life for at least another 1.75 billion years, as long as nuclear holocaust, an errant asteroid or some other disaster doesn't intervene, a new study calculates. But even without such dramatic doomsday scenarios, astronomical forces will eventually render the planet uninhabitable.
- We can't feel Earth's rotation or spin because we're all moving with it, at the same constant speed. Earth spins on its axis once in every 24-hour day. At Earth's equator, the speed of Earth's spin is about 1,000 miles per hour (1,600 kph).
In 1974, Hubbert predicted that peak oil would occur in 1995 "if current trends continue". Those predictions proved incorrect. However, a number of industry leaders and analysts believe that world oil production will peak between 2015 and 2030, with a significant chance that the peak will occur before 2020.
- Peak oil is important because it marks the peak of production of “cheap” oil, generally considered to be conventional crude oil.
- Coal is our most abundant fossil fuel. The United States has more coal than the rest of the world has oil. There is still enough coal underground in this country to provide energy for the next 250 years or more. Trapped inside coal are traces of impurities like sulfur and nitrogen.
- We use them to fuel our airplanes, cars, and trucks, to heat our homes, and to make products like medicines and plastics. Even though petroleum products make life easier — finding, producing, moving, and using them can harm the environment through air and water pollution.
Peak oil refers to the hypothetical point at which global crude oil production will hit its maximum rate, after which production will start to decline. This concept is derived from geophysicist Marion King Hubbert's "peak theory," which states that oil production follows a bell-shaped curve.
- That total exceeds the 256 billion barrels found in Russia, and the 212 billion barrels located in Saudi Arabia. The findings are surprising, and go against conventional wisdom that Saudi Arabia and Venezuela hold the world's largest oil reserves.
- Peak oil theory is based on the observed rise, peak, fall, and depletion of aggregate production rate in oil fields over time. It is often confused with oil depletion; however, whereas depletion refers to a period of falling reserves and supply, peak oil refers to peak, before terminal depletion occurs.
