We're not deploying new renewables "pretty much as fast as we can". We're not even close to doing that. In actuality, we have ludicrously-rich power centers which are actively subsidizing fossil fuels and warring against renewables. Imagine if all that effort were redirected.



> Imagine if all that effort were redirected.

Well, we'd get there faster, of course. But that's still not right now, that would be still many years, especially for the third world which can't afford the investment.


Right now, we have enough energy.

If every home was insulated and had a heat pump, we'd all be richer.

Why havent we done that?

Why, when the initial Ukraine invasion in 2014 caused a gas price spike, did Bjorn Lomborg and other climate change deniers write an article very much like this one, in which he advocated against more renewables, and instead said we needed to invest in research to find the real solution.

So here we are again, 8 years later, and we're doing the exact same thing? Fool me once...


Can you elaborate why you're saying that right now we have enough energy ? Because to me it's obvious that the third world has far from enough energy (like, they'd need multiple times more to reach a first world stanard of living), and even in first world there's not really enough at the moment, as indicated by the EU energy crisis.

Perhaps the currently available energy is sufficient to meet all the needs in a fictional world where every home was insulated and had a heat pump, but I don't live in that world. Perhaps in some future after many years of infrastructure buildup I could live in that world, but that's not right now. And perhaps in a fictional world where 8 years ago more effort had gone into renewables, there would be enough energy for the current consumption, but I don't live in that world either - in the world I live in, the currently installed and immediately available capacity as of 2022 is far from sufficient for meeting our current needs, and if you're saying "Right now, we have enough energy" I am really struggling to understand what exactly you want to say with that. Are you implying that we should curtail our energy use to what's currently available (or less) and feel satisfied at that?


See my other comment for details.

People are trying to confuse matters by talking about Primary energy as if your quality of life has a 1:1 relationship with fossil CO2 released.

So, if we are actually talking about "primary energy" then we would have enough if we used it efficiently. But we dont. Because our politicians prefer burning gas to heating homes. Gas burnt gets them a kickback, warm homes don't.

Hence why all the solutions to this gas price crisis that don't involve burning even more gas get drowned out.

You can say "well we don't have well insulated homes now", yes I know. But maybe you should be asking "Why don't we have well insulated homes?" because that answer will explain more about how the energy crisis plays out than thermodynamics does.


> If every home was insulated and had a heat pump, we'd all be richer.

Yes of course. If every person had a flying car we'd all be richer too.

> Why havent we done that?

Perhaps because the (energy, work) cost of digging heat pumps for every home is too high for us to afford?

How much energy is necessary to create a heat pump and how long does it take for it to pay off?


>If every home was insulated and had a heat pump, we'd all be richer.

I live in an insulated house and am getting a heat pump, but of course, I can already afford my bills. My saving on my energy bill doesn't redistribute the energy to someone else.


Yes it does?
