Energy Group

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

Next meeting: Monday 23rd May 8pm - Monitoring the Earth's Climate from Space - What's Possible and What's Not Mick, who joined the group last year, has worked in the space industry for 20 years planning missions and technologies for environmental monitoring, including projects for the European Space Agency (ESA) and the UK Space Agency (UKSA).

Earth observation satellites are used both to measure the impacts of climate change (such as melting ice caps, sea level rise and land cover changes) and the levels of CO2 and methane in the atmosphere that cause climate change. Many countries have pledged to reduce carbon emissions in the coming years, but how can we know if these promises are actually delivered? Hopefully, future satellite missions will provide independent data to verify this. However, there are limitations. Mick will explain what is possible and what is not.

We conduct meetings online using Zoom. All welcome, contact Nicola for the link.

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.
