Because proven reserves include oil recoverable under current economic conditions, nations may see large increases in proven reserves when known, but previously uneconomic deposits become economic to develop. In this way, Canada's proven reserves increased suddenly in 2003 when the oil sands of Alberta were seen to
Renewable resources are available each year, unlike non-renewable resources, which are eventually depleted. A simple comparison is a coal mine and a forest. While the forest could be depleted, if it is managed it represents a continuous supply of energy, vs. the coal mine, which once has been exhausted is gone.
The reserve list specifies different types of coal and includes countries with at least 0.1% share of the estimated world's proven reserves of coal. All data are taken from the German Federal Institute for Geosciences and Natural Resources (BGR) via BP; all numbers are in million tonnes. [1]
This list of oil fields includes some major oil fields of the past and present. Countries by proven oil reserves 2017. The list is incomplete; there are more than 25,000 oil and gas fields of all sizes in the world. [1] However, 94 % of known oil is concentrated in fewer than 1,500 giant and major fields. [2]
As the name implies, water is held in reserve by a reservoir so it can serve a purpose. For example, in Thailand, reservoirs tend to store water from the wet season to prevent flooding, then release it during the dry season for farmers to grow rice. For this type of reservoir, almost the entire volume of the reservoir functions for the purpose ...
Resource estimates are undiscovered volumes, or volumes that have not yet been drilled and flowed to surface. A non-reserve resource, by definition, does not have to be technically or commercially recoverable and can be represented by a single, or an aggregate of multiple potential accumulations, e.g. an estimated geological basin resource.

Global map of countries by total renewable internal freshwater resources (billion cubic meters) in 2020, according to World Bank [1]. This is the list of countries by total renewable water resources for the year 2020, based on the latest data available in January 2024, by World Bank and Food and Agriculture Organization (AQUASTAT data).
