A third opportunity is waste-heat reuse and district heating, which captures and exports server heat to improve overall efficiency, though practical deployment depends on local infrastructure. Fourth, governments should prioritise regulatory and power-market reforms: predictable tariffs, streamlined permits for on-site generation, and demand-response mechanisms can lower risk and unlock investment, as highlighted in OECD policy reviews.
Finally, Africa may need a hybrid edge vs centralised model, distributing smaller edge sites for latency-sensitive services while building a few high-capacity, liquid-cooled hubs in locations with abundant low-carbon power, stronger grid capacity or naturally cooler climates.
