So to be defined as a reserve, we must have either a proved, probable or possible understanding of its existence. The first is the degree of certainty that it exists: the planet likely has many mineral resources which we have not yet discovered. There are two requirements which determine whether a mineral resource becomes a reserve. It is true that every reserve is a resource, but not every resource is a reserve. The chart explains this distinction visually. However, there is an important distinction between the two. The terms “reserves” and “resources” are often used interchangeably. resources: when does a resource become a reserve? But oil and gas are still growing quickly.ĭefinitions and measurement Reserves vs. Today, coal consumption is falling in many parts of the world. 1įossil fuel consumption has increased significantly over the past half-century, around eight-fold since 1950 and roughly doubling since 1980.īut the types of fuel we rely on have also shifted from solely coal towards a combination with oil and gas. Earlier data, pre-1965, is sourced from Vaclav Smil's work on energy transitions this has been combined with data published in BP's Statistical Review of World Energy from 1965 onwards. In the interactive chart, we see global fossil fuel consumption broken down by coal, oil, and gas since 1800. But fossil fuel consumption has changed significantly over the past few centuries – both in terms of what and how much we burn. The burning of fossil fuels for energy began around the Industrial Revolution. Fossil fuel consumption Global fossil fuel consumption This article presents the long-run and recent perspectives on coal, oil, and gas – how much countries produce and consume, where our fossil fuel reserves are, and what role the fuels play in our energy and electricity systems. They are also a major contributor to local air pollution, which is estimated to be linked to millions of premature deaths each year.Īs low-carbon sources of energy – nuclear and renewables – become readily available, the world needs to rapidly transition away from fossil fuels. When burned, they produce carbon dioxide (CO 2) and are the largest driver of global climate change. Fossil energy has been a fundamental driver of the technological, social, economic, and development progress that has followed.įossil fuels (coal, oil, gas) have, and continue to, play a dominant role in global energy systems.īut they also come with several negative impacts. But the Industrial Revolution unlocked a whole new energy resource: fossil fuels. World consumption may reach 3 214 500t, 2.9% more than the previous crop year.For most of human history, our ancestors relied on very basic forms of energy: human muscle, animal muscle, and the burning of biomass such as wood or crops. Production in the rest of the IOC member countries is estimated at 936 500t. The EU countries are expected to produce 1 974 100t, or 3.8% less than the previous year. The IOC member countries are set to produce 2 910 500t of olive oil in the 2021/22 crop year, or 93.9% of the world total, which is 3.6% more than the previous year. Imports and exports are estimated to exceed 1 million tonnes. Olive oil – Estimates for the 2021/22 crop yearĪccording to official country data and Executive Secretariat estimates, world production is forecast at around 3 098 500t in the 2021/22 crop year, 2.9% up on the previous year.Consumption reached 2 054 000t in IOC member countries and 1 071 000t in non-member countries. The IOC member countries produced 2 809 500t of olive oil in the 2020/21 crop year, which accounts for 93.3% of the world total. Consumption is expected at around 3 125 000t (-4.4%) and imports and exports at 1 122 500t and 1 108 500t respectively. Provisional figures for the 2020/21 crop year put world production of olive oil at 3 010 000t, which is 256 500t or 7.9% less than the previous year. Olive oil – Provisional figures for the 2020/21 crop year.Estimates for the 2021/22 crop year put production at 3 098 500t (+2.9%). Provisional data for 2020/21 point to a 7.9% fall in production for a volume of 3 010 000t. Olive oil production has tripled in the last 60 years to reach 3 266 500t in the 2019/20 crop year.
