Energy Group

For group members: Email the group (not just Nicola) - Glossary

Next meeting: Wednesday Nov 16th 8pm - Contractors An informal discussions about contractors - how to find them, how to verify they are competent and how to get the best out of them when you have them. Ideally this will lead to advice on our website, for setting reasonable expectations. If you have dealt recently with contractors for energy efficient retrofit or low carbon heating, we are especially interested to hear from you. However, you will also be welcome if you are just looking for advice.

We conduct meetings online using Zoom. All welcome, contact Nicola for the link. If you have another topic you would like to raise please let Nicola know.

Energy saving survey

In this time of energy shortage it is very important that we all reduce energy consumption - even if we can afford to carry on as usual. This is because wholesale gas and oil prices will keep rising until enough people reduce demand that the supply is sufficient. Reducing demand helps keep prices low for everyone. With this in mind please fill in our short survey about what you are doing to save energy at home - both gas and electricity. It may give you some ideas and you can give us your favourite tips!In a few weeks we will collate them and report on them in the Transition Cambridge blog.

New - Guide to getting an air source heat pump

For most homes, an air source heat pump is the best way to getting off gas but converting your central heating system from a boiler to a heat pump is not a totally trivial exercise. Building on experiences from the energy group members, this guide explains how to set about it with a minimum of jargon.

New personalised advice tool

The energy group have a completely new energy advice tool which you can use to get ideas for improving your home. The suggestions update dynamically according to your aims (indoor air quality, keeping warm, reducing bills, carbon emissions, keeping cooling in summer) and what you already have in your home. Please do try it out.

Updated fact pages -

Have you seen our newest fact pages: Low carbon heating options and Underfloor heating. Also the Heat Pumps FAQ has had a major revamp.

What are we doing to save energy and carbon emissions?

You can read suggestions from some Energy Group members here. Suggestions are ordered by cost - three of them are less than 100.

All about embodied energy

Nicola has written an overview of embodied energy/carbon issues including how you measure it and what are the implications. For example, in some cases (like conventional cars) operational energy dominates, in other cases manufacturing or materials (like carpets). In other cases both are important. The report includes comments issues raised in our discussion on the topic. Read it on her website here

All about the circular economy

Nicola has written an overview of the circular economy and what we can do to promote it. (e.g. get your stuff mended professionally, consider renting rather than buying stuff). This includes comments issues raised in our discussion on the topic. Read it on her website here

Energy advice pages

See here for advice on saving energy, energy efficient heating and generating renewable energy at home.

Help Wanted

Please email us if you would like to help or contribute your ideas, whether or not you can come to meetings.

At the moment we are particularly looking for assistance with:

  • Authoring FAQ pages and fact sheets, both writing the answers and writing the questions so you don't have to be an expert to help. Some ideas for more:, heritage buildings ...

By the way, Nicola's thermographic pictures of houses in Cambridge are still here.
