The problem with COP26
The IPCC recently conducted a study into the combined effects of all the agreed targets of the countries taking part in the ongoing COP talks. Tucked away in the report is this: “The available NDCs of all 191 Parties taken together imply a sizable increase in global GHG emissions in 2030 compared to 2010, of …
Repairing an off-grid wind and solar electrical system
We recently blogged about a project: ‘rebuilding a home, and changing the surrounding fields from dead agricultural land into an oasis of natural life’ – as well as building an off-grid electrical and heating system. Here’s the next in the series – about repairing an off-grid wind and solar electrical system.

Jon Hallé: Introducing the Big Solar Co-op, and how you can help renewables and the co-op sector
Today I’m speaking with Jon Hallé. We go back about 20 years. You ran courses on how to make biodiesel for Lowimpact, back in the early noughties, and you authored a book for us about making biodiesel, that sold about 15k copies in the first year. It caught the zeitgeist then, but of course diesel …
How you can help get solar onto more roofs in your community: the Big Solar Co-op

Do energy-saving measures actually increase overall energy use?
Having worked in the environmental field for 30 years, I’ve watched the situation get worse every year, to the point that it might already be irreversible, and we don’t know what damage it’s going to do to us, exactly. That’s pretty insane, and so
Chris Cook’s tour of the oil markets: from Nixon to Trump

A south-facing, rammed earth, straw-bale-insulated house doesn’t need heating; why aren’t all new houses built this way?
Rowland ran rammed earth building courses with us for years. He said then that a C-shaped, rammed earth house with straw-bales for external insulation, and as much glass on the south side and as little glass on the north side as possible, wouldn’t need any heating. We wanted to catch up with him to learn …
