If a third of global citizens ever do wind up with some form of broadband access running at 10 Mbps, and current core network technology does not change, about half of all global electricity supplies will be consumed just for the transport and access of that bandwidth.
Obviously this doesn't scale. Among the solutions is use of more photonic techniques in the core and access networks.
Executives at ADVA Optical Networking argue it is better to use layer 2 rather than layer 3, and optical transport instead of layer 2, where possible.
High-density routers and switches in data centers also will help. In the access network, optical rather than electrical technology is preferable, especially passive optical networks.

33% Broadband Penetration at 10 Mbps = Half of Global Electricity
Gary Kim has been a digital infra analyst and journalist for more than 30 years, covering the business impact of technology, pre- and post-internet. He sees a similar evolution coming with AI. General-purpose technologies do not come along very often, but when they do, they change life, economies and industries.
