So w- what are some of the levers that have worked in the past when governments have tried to increase efficiency, whether that's through tax breaks or trying to change people's behavior?

behavior?So I said at the start, there's a lot of potential to become more efficient, and I think that's because despite what I've said about this increased focus and the, and the real, very real progress we have made, governments just don't focus on the demand side of, of energy as much as they do on the supply side of energy.

That- that's fairly normal.

They think about how do we meet our supply needs, how do we build our infrastructure, where is our energy gonna come from? But we see that governments that do focus more on the demand side are rewarded in terms of greater levels of efficiency leading to lower bills, lower imports, lower carbon emissions.

We know the potential is there.

And we see around the world many really good examples of policy.

It's almost as if, as every- if everybody did what everybody else is doing, we'd have the perfect energy efficiency policy mix because there's good examples in every continent of every types of policy.

Now, what does the data tell us about the, the impact on the poorest groups? Are they hit hardest by, by energy shocks, and if so, why is that?
