Centre for Alternative Technology (CAT)
If ever you’re near Machynlleth in North Wales check out CAT. We went there a couple of days ago. It’s an inspiring place. They offer a free information service. The one thing that I learned which made a big impression was that we don’t need any new technology to become carbon zero- we have all the knowledge and technology that we need - we just need to act.
