Decarbonizing world economies implies the deployment of “green technologies”, meaning a
renovation of the energy sector towards using renewable sources and zero emission
transport technologies. This renovation will require huge amounts of raw materials, some of
them with high supply risks. To assess such risks a new methodology is proposed,
identifying possible bottlenecks of future demand versus geological availability. This has
been applied to the world development of wind power, solar photovoltaic, solar thermal …

Reducing emissions global economies demands the development of" green technology,"
which entails a reorganization of the energy sector to use renewable energy sources and
nitrogen transportation systems. This reconstruction will need massive quantities of raw
materials, some of which are in short supply. A unique method for spotting potential
drawbacks of future demand versus geophysical supply is proposed to assess potential
risks. This was applied to the international development of wind electricity, photovoltaic …
