Oh, we definitely need to increase elasticity of supply, specifically short term elasticity of electricity supply.
It's just that those graphs of declining electricity consumption per capita have nothing to do with supply elasticity. They're not markers of stagnation or degrowth. They're markers of increasing efficiency, increasing productivity of our use of electricity, and decreasing demand.
Energy supply in the US is almost entirely a function of demand. Even now. And the challenges we have are all about speed and short term elasticity, and mostly about poles and wires rather than generation.
And indeed, now that demand is rising, because we've found possibly the highest value way to use electricity (AI), supply is rising once more.
Supply follows demand. Generation is plentiful. Poles and wires are our short term elasticity challenge.
@packyM @ramez Packy is right, if we don't build more energy supply either the AI boom will move to China or else retail electricity rates will skyrocket, both of which are bad. The demand is there, we lack supply elasticity.
