8 FROM AMBITION TO ACTION

- HOW GERMANY INTENDS TO USE HEAT PLANNING FOR ITS AMBITIOUS GREEN AGENDA By Christian Bjerrum Jørgensen and Willy Winkler

This magazine was planned just before the crisis in Ukraine, and we did not have the chance to adjust the ar- ticles accordingly. Therefore, you may find that we avoid a situation – but we do not. Instead, we have a theme that is even more relevant and of concern to everyone in Europe, where we see strong demands to get rid of natural gas faster now than ever. Germany is on the move with the new heat planning rules; in Denmark, we see a lot of small and large gas areas be- ing converted away from gas one by one. We have a new heat plan called "Heat Plan Denmark 2021" that we now discuss how to make even more robust and faster to reach at least a part of our short-term goal to avoid gas. But we also have other articles that briefly touch on the theme "conversion from gas" – digitalization is essential and will lead to less heat demand and, therefore, less gas. The article is about achieving lower return temperatures – an important matter to become more efficient in our business. Our editorial this time is about women in our industry – and the fact that they are way too few. The lack of diversi- ty in our business is well-known. Now they do something about it in the UK through the DH Divas - an exciting pro- cess to follow that already gives results. We all lack all skills; it is important that we invite everyone - who shows inter- est - into our industry. It is the only right thing to do, and it is also good common sense."

WANT BETTER DISTRICT HEATING NETWORKS? LETWOMEN FLOOD IN

There’s a photograph doing the rounds on LinkedIn. It’s ameeting room set for lunch. White linen, flowers on the table, lots of natural daylight. Lots of men. Lots of blue suits. Lots of grey hair.

By Rachael Mills, Co-Founder, District Heating Divas

The birth of a movement Three years ago, over a quiet gin and tonic, my business partner Liz Warren and I wondered if oth- er women working in the DH sector would be interested in getting together. Other women we knew thought it was a good idea, and so in April 2019, we hosted a small lunch, and the District Heating Divas were born. The older I get, the more I become aware of when I’m the only woman in the room. Maybe it’s self-awareness; maybe it’s other strong women opening our eyes. It’s not the fault of those individ- ual men around that table, but everyone has a role to play in making a change. Everyone of those men will have worked hard to rise to the top of their profession and earned their seat at that table. Most of them will have families. Many of them will be vocal advocates of their female colleagues. But where are the women? Where are the people of colour? The photo in question happened to be taken at a security conference, but there are plenty of other male-dom- inated industries – including the district heating (DH) sector. The good thing is that the photo was called out on social media1. The bad thing is that it still needs to be.

The energy sector is undergoing a

transformation, presenting a wide range of challeng- es and opportunities, from digitalisation to decarbon- isation and changing con- sumer demands. Success will mean attracting and retaining a diverse pool of talent capable of bringing the necessary technical and leadership skills, and

At its simplest, the Divas is an informal business networking group for all women working in the DH sector. But it’s much more than that. It is connectedness. It’s open and welcoming. It’s friendly and collaborative. It’s inspiring and supportive. It’s fun!

The Divas have grown into a mighty group of phenomenal women. We now have:

Over 300 women in our LinkedIn group Over 150 women attending regular regional and national meetups (both online and in real life) A hugely successful mentoring programme – the Heat Exchanger – now recruiting its third cohort A STEM careers video that’s about to premiere

Oh – and we run the most interesting, engaging and memorable conferences you’ve ever been to! And it’s all done pro bono – for free – because the women involved value coming together.
