BGR provides the biennial energy study which covers data and developments concerning German and Global energy supplies. In addition the study also provides information on the global generation of renewable energies, including geothermal energy and hydrogen. 

Uranium is the raw material used to produce fuel for long-lived nuclear power facilities, necessary for the generation of significant amounts of baseload low-carbon electricity for decades to come. Although a valuable commodity, declining market prices for uranium in recent years, driven by uncertainties concerning the evolution in the use of nuclear power, have led to significant production cutbacks and the postponement of mine development plans in a number of countries and to some questions being raised about future uranium supply.

Data cited at: World Nuclear Association Definition of indicators: at). Operable = Connected to the grid. b). Under Construction = First concrete for reactive reactor, or major refurbishment underway. c). Planned = Approvals, funding or commitment in place, mostly expected in operation within 8-10 years d). Proposed = Specific program or site proposals, timing of start of operation very uncertain. Note: Nuclear Electricity Generation values ​​are annual and value changes every year.

A number of enrichment processes have been demonstrated historically or in the laboratory but only two, the gaseous diffusion process and the centrifuge process, have operated on a commercial scale. In both of these, UF6 gas is used as the feed material. Molecules of UF6 with U-235 atoms are about one percent lighter than the rest, and this difference in mass is the basis of both processes. Isotope separation is a physical process. Large commercial enrichment plants are in operation in France, Germany, Netherlands, UK, USA, and Russia, with smaller plants elsewhere. New centrifuge plants are being built in France and USA. Several plants are adding capacity. China’s capacity is expanding considerably, in line with domestic requirements. With surplus capacity, Russian plants operate at low tails assays (underfeeding) to produce low-enriched uranium for sale
