Vaclav Smil • Making the Modern World: Materials and Dematerialization
As a result, global production of these four indispensable materials claims about 17 percent of the world’s primary energy supply, and 25 percent of all CO2 emissions originating in the combustion of fossil fuels—and currently there are no commercially available and readily deployable mass-scale alternatives to displace these established processes.
Vaclav Smil • How the World Really Works: The Science Behind How We Got Here and Where We're Going
Moreover (as will be explained in chapter 3), we have no readily deployable commercial-scale alternatives for energizing the production of the four material pillars of modern civilization solely by electricity. This means that even with an abundant and reliable renewable electricity supply, we would have to develop new large-scale processes to prod

Reality thus presses in from both ends. The sheer scale, cost, and technical inertia of carbon-dependent activities make it impossible to eliminate all of these uses in just a few decades.
