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.
Earth materials include minerals, rocks, soil and water. These are the naturally occurring materials found on Earth that constitute the raw materials upon which our global society exists. Earth materials are vital resources that provide the basic components for life, agriculture and industry. [1] [2] [3]
Traditionally, a fixed stock paradigm has been applied, but Tilton and Lagos (2007) [9] suggest using an opportunity cost paradigm is better because the usable resource quantity is represented by price and the opportunity cost of using the resource. Unlike energy minerals such as coal or oil – or minerals used in a dissipative or metabolic ...

The depletion of resources has been an issue since the beginning of the 19th century amidst the First Industrial Revolution.The extraction of both renewable and non-renewable resources increased drastically, much further than thought possible pre-industrialization, due to the technological advancements and economic development that lead to an increased demand for natural resources.
Mineral Resources are further sub-divided, in order of increasing geological confidence, into inferred, indicated and measured as categories. Inferred Mineral Resource is the part of a mineral resource for which quantity, grade (or quality) and mineral content can be estimated with a low level of confidence. It is inferred from geological ...
