Renewable energy sources are even larger than the traditional fossil fuels and in theory can easily supply the world's energy needs. 89 PW [32] of solar power falls on the planet's surface. While it is not possible to capture all, or even most, of this energy, capturing less than 0.02% would be enough to meet the current energy needs.
Proven reserves are a subset of producible reserves. Proven reserves (also called measured reserves, 1P, and reserves) is a measure of fossil fuel energy reserves, such as oil and gas reserves and coal reserves. It is defined as the "quantity of energy sources estimated with reasonable certainty, from the analysis of geologic and engineering ...
Map of countries with proven oil reserves - according to US EIA (start of 2017) Trends in proven oil reserves in top five countries, 1980–2013 (data from US Energy Information Administration) A map of world oil reserves according to OPEC, January 2014
Global energy consumption, measured in exajoules per year: Coal, oil, and natural gas remain the primary global energy sources even as renewables have begun rapidly increasing. [1] Primary energy consumption by source (worldwide) from 1965 to 2020 [2] World energy supply and consumption refers to the global supply of energy resources and its ...
Resources are re-classified as reserves following appraisal, at the point when a sufficient accumulation of commercial oil and/or gas are proven by drilling, with authorized and funded development plans to begin production within a recommended five years.
Schematic unconventional reservoir classification expressed as fluid energy vs flow potential based on initials without stimulation. Unconventional (oil and gas) reservoirs, or unconventional resources (resource plays) are accumulations where oil and gas phases are tightly bound to the rock fabric by strong capillary forces, requiring specialized measures for evaluation and extraction.
A 2016 conservative estimate by the World Energy Council set the total world resources of oil shale equivalent to yield of 6.05 trillion barrels (962 billion cubic metres). [2] For comparison, at the same time the world's proven oil reserves are estimated to be 1.6976 trillion barrels (269.90 billion cubic metres).
Nuclear energy – energy in the nucleus or core of atoms [1] Nuclear fusion; Nuclear reactor; Nuclear reprocessing; Oil drilling; Oil platform; Oil refinery; Oil shale; Oil well; Osmotic power – or salinity gradient power – is the energy available from the difference in the salt concentration between seawater and river water.
