> And energy is a massive component in the price of almost everything we consume.
Is it really? What would be different if energy was much cheaper? Would we have more advanced rockets or robots or phones? Better CPUs? More and cheaper housing built in dense cities? Cheaper education or medicine? More job security? Even more food?
I realize that energy is an important input into some industrial processes, but I don't really think we're constrained by it (or by manufacturing in general) right now...
It was only a single point of the OP's that you're targeting but I have to agree (I agree with other OP points though).
Would a lower energy cost bring wages up? No reason to believe that would be the case.
Would it lower the cost of goods so that at least the working poor could have a better standard of living?
Perhaps, but how much of the cost of a good is the energy, how much labor and raw materials? Would we see even more job loss due to lower cost of energy as it becomes even cheaper still to automate?
(Edit: to be clear, OP wasn't saying lowering energy costs would do anything more than lower the cost of goods. But that statement alone, coupled with the article showing declining wages, etc. suggests OP was implying lower energy costs could reverse or stop the trends shown.)
Portion of cost in GDP is not equal to importance.
What is the cost of water in the GDP? Much less than the cost of the energy. What would be the GDP without water? Nil. There would be no GDP because we would all be dead.
Water's cost is much less than the cost of energy because supply is high. If water was more scarce (or if water rights weren't screwy in many places), it would be much more expensive, and it definitely would be more of a limiter.
Also, you somehow equated the complete lack of a resource with a price increase. What would the effect on the GDP be without any energy? Well, we might not all be dead, but a significant portion of us might for various reasons including wars and massive world unrest because of instability. Even if you ignore all that, the economy as we know it would grind to a halt.
> [H]ow much of the cost of a good is the energy, how much labor and raw materials?
For physical goods, most of it. Raw materials in particular aren't expensive except in terms of the energy required to extract them and process them (modulo supply and demand).
For labor it's more complex, but in general falling energy costs drive capital investment in automation (displacing and lowering demand for less-skilled labor) to lower price and capture greater market share (in order to get a return on the investment of capital), lowering labor's share of the final price, and the Jevons paradox drives increased consumption of the lower priced goods (as well as the lower priced energy). Software has been driving the same sort of dynamic for a while, though the way it affects industries seems to be more contingent, 'lumpier', and less predictable (eg. in hindsight, the disappearance of the travel agent as a result of online booking was somewhat obvious, but AirBnB effectively adding a lot more inventory to the market wasn't).
Not sure what happens when software and energy both more directly affect each others' supply and consumption, but the effect on the rest of the economy is going to be... interesting. Smarter energy grids that shift the economics of energy plants and sources at different scales; vehicles, homes, factories, & data centers that can all adjust their energy use/storage to take advantage of spot pricing, energy costs driving the ROI of training machine learning models etc. and thus changing the return on investment in compute capacity (and in software efficiency), and so on. There are a lot of feedback loops, and as "software eats the world", more (unanticipated) feedback loops will be created.
Energy allows you to trade one thing against another. For instance, we have a "white sand" shortage (for making chips). (Vastly) more energy would mean more kinds of sand would be perfectly fine for production.
So energy is special: it is the universal input to industrial processes. Unlimited energy would make almost anything (more) plentiful. We'd essentially have more of what people want, whatever that is. So yes, more and cheaper housing in dense cities, but it's probably easier to see that faster and better transport options would result. That limits everything, not just manufacturing.
> I realize that energy is an important input into some industrial processes, but I don't really think we're constrained by it (or by manufacturing in general) right now...
You should probably reevaluate this. Energy costs are most of the costs of production much of the time. Sometimes it is hidden in the costs of components or of the labor involved, but it’s fundamentally an energy cost.
What could a neural networks exponentially larger than GPT-3 could accomplish? You could probably use it to create more efficient GPUs. And then other more efficient tools in adjacent industries. Hard to say where the virtuous cycle would end... constraints in manufacturing would evaporate as the rate of technological breakthroughs increase.
Who said anything about better? Cheaper energy = cheaper everything, but that doesn't mean that quality is necessarily constrained by current energy prices (although that also doesn't mean there aren't ways in which it could be).
We wouldn't need rockets at all, or at least far less; we could power things like launch loops and railguns to get things into space (and then either settle for rockets to circularize or else use laser ablation or orbital tethers or other fancier systems to circularize).
> or robots or phones? Better CPUs?
Robots, phones, and CPUs all benefit from power being readily available. For the latter-two, power storage is a critical factor as well, but it's at least a little bit less critical when there are ample places to cheaply recharge.
> More and cheaper housing built in dense cities?
Dense housing tends to require things like elevators (unless you expect people to climb tens or hundreds of flights of stairs every day), climate control (in places naturally too hot or too cold for humans to safely live), and the very equipment and materials to construct that housing in the first place (cranes and bulldozers don't run on magic, and neither do steel mills or window factories). Not to mention the things people like to be able to do within those homes, the vast majority of which require electricity. Cheaper electricity makes these things cheaper.
> Cheaper education or medicine?
Electricity is typically required for distance education and telehealth. It's also typically required for modern education and medicine, period. Cheaper electricity makes these things cheaper.
> More job security?
Not only does energy itself tend to create jobs (especially solar, what with all the rooftops and parking lots begging to be made useful with solar panels), but so does the resulting burst in commercial and industrial opportunities when people are able to drive down or outright eliminate electricity's cost to business.
> Even more food?
Vertical farming at scale will absolutely require more electricity. So will water production; desalination is typically an energy-intensive process, but with enough energy production, it could make water shortages in places like California a thing of the past. Even traditional/flat farms have tractors and combines and other equipment that are costly to run; slash those run costs, and farming just got that much more viable for smaller farmers that can't otherwise foot the bill.
> I don't really think we're constrained by it (or by manufacturing in general) right now...
Right now the energy and manufacturing capacity we have is built on egregious exploitation of fossil fuels, particularly coal and oil. Those won't last forever; either they'll run out, or we'll end up wiping ourselves out with the resulting greenhouse gases (or probably both).
From what I understand, the main technological blocker (as opposed to various political and economic blockers) is the need for superconductors to achieve reasonable energy efficiency. With cheap energy, that's less of a pressing need (and further, cheap energy = more energy to throw at cryogenic cooling systems to induce superconductivity in less-exotic materials).
Superconductors are also used for thermal reasons. Generating strong magnetic fields through high current in a resistive material will put out a lot of heat.
