From what I've read, the immediate effect will likely be worse for CO2 emissions, because the alternative to (liquefied) gas is often coal power. Also, the various inputs that are needed for global manufacturing are also affected, so maybe even renewable tech gets more expensive.

I'm not saying that the dependence on the middle east was good, but I think it's good to keep in mind that this was a pretty stable equilibrium even with the various questionable countries involved until the US initiated a global supply shock without a good reason.

There are short term and long term effects. Overall these are good changes.

There are a couple of points to make here. The lead time for new coal/gas plants is years. If it's not planned already, any newly planned plants are unlikely to come online this decade. The supply chains simply can't handle building more turbines and it takes years to fix that. Also, that investment is super risky in it self.

Another point is that the cheapest and fastest way to add new capacity to grids is via renewables. That's why we see record breaking new capacity coming online on a regular basis.

There is indeed a short term increase in emissions from electricity plants because the fastest way to bring more capacity online is to use existing underused plants. A lot of gas and coal plants are no longer running full time because they are too expensive to operate. But they haven't been decommissioned either. Some gas plants actually are used as peaker plants. Most older coal plants take too long to warm up for this. So, yes short term the expensive but quick way to provide extra power is via these plants. But of course, as soon as something more affordable comes online, these things go back to being utilized less. There are many tens/hundreds of GW of renewables and batteries being deployed in the next few years.

Data centers add to all this pressure. That's long term a good thing because these too will want to long term reduce their OpEx by cutting as much dependence on gas/coal as possible.

A final point to make is that despite all these increased emissions, there are also decreased emissions from electrification. Even if the power for an EV comes from an efficient gas/coal plant, it's actually better than the alternative of burning petrol in a combustion engine instead. Less emissions this way. Same for heat pumps. With a COP of 3-4, they outperform burning gas by 3-4x using electricity. Even if that electricity comes from a gas plant operating at 40-50% efficiency. Less gas gets burned.

So these are all good effects even if the reason is a bit sad and unnecessary. This crisis is unnecessary. But I like that it is helping to kill fossil fuel companies faster. This long term erodes confidence in the market as a whole and drives decision makers to do exactly what the article suggests: cutting the dependency on fossil fuels as fast as possible. It's already resulting in measurable reductions in oil/gas imports in some countries.
