According to the U.S. Energy Information Administration’s (EIA) International Energy Outlook 2023(IEO2023), the global supply of crude oil, other liquid hydrocarbons, and biofuels is expected to be adequate to meet the world's demand for liquid fuels through 2050. There is substantial uncertainty about the levels of future liquid fuels supply and demand. The IEO2023 projectionsreflect some of this uncertainty ina Reference case, High and Low Economic Growth cases, High and Low Oil Price cases, and High and Low-Zero Carbon Technology Growth cases in its projections. The oil resources currently in the earth's crust, in combination with expected production of other liquid fuels, are estimated to be sufficient to meet total world demand for liquid fuels in all cases of the IEO2023.
An often cited, but misleading, measurement of future resource availability is the reserves-to-production ratio, which is calculated by dividing the volume of total proved reserves by the volume of current annual consumption. Proved reserves are an accounting concept that is based on known projects, and it is not an appropriate measure for judging total resource availability in the long term. Over time, global reserves will likely increase as new technologies increase production at existing fields and as new projects are developed.
