What Is "Earth Notes" / Earth.Org.UK / EOU?

What is Earth Notes about? Who creates the content?

This site is about practical steps that I have taken to make my own life (and that of my family) a little better and lower-carbon.

Cutting carbon at home to slow climate change, with high- and low- tech. Living a normal life — no hair shirt required! aka EOU aka "Earth Notes" celebrated its 10th birthday in 2017.

Early in 2007 I had a small brainwave and decided to create a simple single-page microsite about composting vs domestic solar power. It was an issue that was exercising me at the time, and the remnants are now in their own page.
Now, something like 10 years after that 1-pager idea, Earth Notes [was] well over 100 pages

All "Earth Notes" content is written by Damon Hart-Davis.

Photos and images are largely from Damon, some via the Gallery. In all other cases appropriate permissions are held or available, up to the images being in the public domain.

For images from others, look for:

  • Upper-case initials at the very end of the image name before the extension, eg some-image-DHD.jpg would be an image by 'DHD', ie Damon in this case.
  • A text file alongside the image file at URL X as X.txt. An 'information' link 'i' may be automatically inserted in the page in some cases.
  • Description of the origin or thanks in the body text and/or image alt text.

Who is Damon and why does he care about energy?

See Damon's home page for a bit more on him, education, CV, etc.

Here's how Damon got into optimising energy after being a UK Internet pioneer, working in defence, oil and banking!

A few years ago I suddenly saw my energy bills as another performance metric that I could tweak just like optimising Lehman Brothers' derivatives calculations that I was nominally paid squillions to do.

In fact, this whole area is full of numbers and graphs and science and gadgets and interesting techie puzzles, never mind the grand+ per year that I'm saving on my energy bills or indeed that "hippy commie yoghurt-knitting greenie" conspiracy about cutting carbon footprint to help avert global warming.

From aerogel and LEDs to iButtons and thermal imaging, you should see some of the fun I've been having!

Why Can You Trust Earth Notes?

Earth Notes aims to be clear, honest, accurate and transparent.

At the end of most articles you will find a section with sources and links relevant to the article, sometimes arguing against the article if the source and counter-argument seem plausible.

Earth Notes is all about reducing climate change. Even unpalatable ideas may need to be considered to that end. Views may change over time as evidence accumulates. Articles will be updated as appropriate to reflect those changes. Earth Notes will continue to report these "inconvientent truths", annoying nuances and real uncertainties as necessary.

Many data sets are published on the site, often data gathered by Damon Hart-Davis, but sometimes from third parties.

Earth Notes uses metadata such as to help maximise machine-readability of material on the site, including data sets, as well as enhancing use with social media and search engines.
