Lithium is one of the elements critical in a world running on renewable energy and dependent on batteries. This suggests that lithium will be one of the main objects of geopolitical competition, but this perspective has also been criticised for underestimating the power of economic incentives for expanded production.

A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. [1] An example is carbon-based fossil fuels. The original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas.
Renewable energy in developing countries is an increasingly used alternative to fossil fuel energy, as these countries scale up their energy supplies and address energy poverty. Renewable energy technology was once seen as unaffordable for developing countries. [ 200 ]
Grid energy storage, also known as large-scale energy storage, are technologies connected to the electrical power grid that store energy for later use. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources like nuclear power , releasing it when needed.
It encompasses energy contained in raw fuels and other forms of energy, including waste, received as input to a system. Primary energy can be non-renewable or renewable. Total primary energy supply (TPES) is the sum of production and imports, plus or minus stock changes, minus exports and international bunker storage. [3]
Energy storage helps overcome barriers to intermittent renewable energy and is an important aspect of a sustainable energy system. [156] The most commonly used and available storage method is pumped-storage hydroelectricity , which requires locations with large differences in height and access to water. [ 156 ]
The energy to perform this is extracted from renewable sources such as wind power. Then, the hydrogen is reacted with compressed carbon dioxide captured by direct air capture . The reaction produces blue crude which consists of hydrocarbon.
Uranium-235 "burnt" in conventional reactors, without fuel recycling, is a non-renewable resource, and if used at present rates would eventually be exhausted. A cutaway model of the 2nd most powerful presently operating fast breeder reactor in the world. The , at 600 MW of nameplate capacity is equivalent in power output to a natural gas CCGT.
