Renewable Energy

The Arithmetic of Sustainability ← Series Home The current discourse surrounding sustainable energy is frequently dominated by “twaddle.” Everyone agrees that transitioning away from fossil fuels is crucial, and individuals are encouraged to “make a difference,” yet many of the actions and proposals suggested simply don’t add up when scrutinized numerically. This high level of “twaddle emissions” arises because public debate often becomes emotional—concerning wind farms or nuclear power, for example—and people rarely discuss concrete numbers. If numbers are mentioned, they’re often cherry-picked to create an impression, sound impressive, or score points in arguments, rather than genuinely contributing to thoughtful discussion. ...

The Arithmetic of Sustainability ← Series Home Having quantified the “red stack” of consumption and defined a necessary reduction strategy for transport and heating, we know that the future sustainable society requires meeting an electrical demand of 48 kWh/d per person (120 GW nationally), representing nearly a tripling of current UK delivered electricity consumption. If this plan is to be technically feasible and not a “pipedream,” we must now rigorously calculate the production side—the “green stack”—to determine how much energy Britain can realistically generate from its own renewable resources. ...
