Thinking about those items on my low-tech wishlist, I've been looking for more information on the topic, and have been browsing the website of Low-tech Magazine.
Apart from the odd article that suggests humans revert to (ab)using animals (like the idea of going back to horses instead of tractors -- why is it always this binary?), which obviously presents problems from a vegan/animal-rights perspective, the site is full of good ideas and very useful background material.
It even provides links to an amazing place in Belgium called The Museum for Old Techniques that is a repository of past tools, methods and texts, a kind of education centre too.
But back to the original site, Low-tech Magazine: there are unexpected features such as "The Ugly Side of Solar Panels" which raises (incorporating its own corrected errors with strikeout!) some of the issues we have often worried about, e.g. the energy-use and pollution generated by the production of solar panels themselves. The article reminds us that "solar cells are far from a zero emission technology"... but I'll leave you to read it for yourself if you're interested.
