silver can only make a marginal contribution to the silver supply for PVs in the near term.
13 Rapid
expected growth rates of the PV industry coupled with a 25-year PV module lifetime means that
recycling rates would have to increase considerably to materially impact silver supply. At present, the
recycling industry for PVs is still very small as very few PVs are currently reaching the end of their
lifespans However, a simple count of facilities does not fully capture the scale of expansion. For additional
context, we also looked at how data centres have grown in terms of their IT power capacity. IT power
capacity refers to the computing capacity of operating servers, storage and networking devices within
data centres and it is typically measured in megawatts or gigawatts. Unlike the count of data centres,
which can vary widely in size, purpose and technological sophistication, IT power capacity reflects the
density and processing capacity of facilities. While the number of data centres grew by 11x since 2000,
we estimate that total global IT power capacity grew by an estimated 53x, from 0.93 GW in 2000 to
nearly 50 GW in 2025 (Fig. 8).
