It's an automatic feedback loop.

In a renewable grid, the electricity is not generated by things that are spinning.

So what happens is you can't any longer rely on the old analog system that the frequency is the signal for what you need to do.

Instead, you need digitalization and access to, you know, you need to be reading what is the load digitally and you need to be able to respond digitally.

You know, for example, by using batteries to be able to either soak up power or dump some onto the grid quickly to maintain that kind of supply and demand balance of which the frequency is an indicator.

So first of all, we should say that, you know, look, some of the most committed, dedicated and smart people I know include grid engineers.

The sense of mission, professionalism and dedication, plus absolute technical expertise is off the charts.

Let's note that.

I think there are a couple of features of any transition.

The first one, by the way, is the assumption that we need a grid of, say, 50 hertz in the European figure, right?

Because if you're like in the traditional grid, where the frequency was a byproduct of how we were generating it, as well as we controlled it, everyone's alarm clocks used to run off the grid frequency.

Obviously, these days, they don't.

They've all got microprocessors and use internet signals and stuff like that.

On the whole, the equipment that relies on the grid frequency now is going to be things with big motors, especially a large industrial equipment.

And at some point you start saying, should we open up a debate

that involves the demand side as well as the supply side.

And this applies to so much stuff in the world of energy, by the way, and I'd love to talk about some more of those.

And saying like, over time, rather than having this kind of religious dedication to extremely tight grid frequency, heavily synchronized across the entire system, are we going to open ourselves up to a grid which has flexibility in that world as well?

Now,

Okay, so first of all, the last thing on that grid issue,
