7am · Mega data centres in bed with big gas: how fossil fuels are powering the AI boom · 7 Jun 2026 podcast

And then there's very, very few jobs that are ongoing.

Really, you just need someone to kind of walk the halls and maintain the systems.

Sure.

I was lead author on a report that was released by Greenpeace Australia recently.

And what we found is that when data centers connect to the grid, you actually end up incentivizing the generation of coal and gas because you're simply increasing demand.

You put constraints on power prices.

And then, of course, there's all of the flow-on impacts in terms of local water consumption and air pollution.

So these are all major constraints that have existed for a long time.

Data centers have always needed water and power.

The difference now is simply the scale.

They've gone from manageable problems to really very unmanageable and difficult and thorny problems.

So what we look at in the report is simply how much renewable energy would be needed to cover off the growth of data centers.

It's a very large amount of new capacity, and the industry itself is not showing that it's prepared to build that amount of new capacity.

Yeah, so the way this generally has worked with technology companies around the world is that they will make a claim to either having zero emissions from their power consumption or they'll market their services as 100% renewable.

A lot of them rely on a mechanism very similar to carbon offsets, if people are familiar with that, where you buy a certificate created by a renewable energy generator.

The logic behind the claim is that because you bought that certificate,

you can kind of claim those emissions reductions as your own.

But that generation would have happened anyway.

The renewable energy, the wind farm would have pumped out those electrons regardless of whether or not you bought that certificate, which means the net results and the reality of the grid, really all that happens is that you add a bunch of new demand, emissions increase, and then there's a bit of paper shuffling that goes on around renewables.

So what we've found in our report is that
