This year, governments have laid out some of the most ambitious environmental targets we've ever seen.

Boris Johnson's UK government has enshrined a pledge into law to cut emissions by 78% by 2035.

And the Biden administration has pledged to cut emissions by over 50% of 2005 levels by 2030.

And industry leaders have been signing up to Pacts, left, right and center.

A great thing about Pax is that gets the initial momentum by the leaders to say,

in fact, this is possible, and even for the

challenges we don't know how to solve yet, we'll come together in collaboration to find the answers

to these challenges.

While innovators get together to find solutions to the big challenges, today on the show we're going to be looking at energy and innovation through the lens of organizations, from tech

to people to buildings.

We'll be finding out which technologies can make us more efficient today.

How to get to grips with managing disparate legacy assets, and whether dropping a data centre in the ocean is a viable solution.

All that and much more.

I'm Michael Bird, and this is Technology Untangled.

When we look at the big picture, it's clear that producing and using more renewable energy is a fundamental target for tackling climate change.

So to set the scene, I asked HPE chief technologist Ian Henderson to help us understand where we are

with energy today.

I think the UK has actually made pretty good progress. We've got a long way to go.

But, you know, I think we've done a lot in reducing the level of fossil fuels,

but we're still having to make a significant investment in nuclear, you know, quite controversially.

And there are big changes of foot, you know, with stopping new house builds having gas boilers

and moving to new technology like air source or ground source heat pumps. Not so easy to retrofit that,
