This talk, consisting of five distinct parts, is intended to show the audience how to get electricity without needing a grid connection. It will give information on Which energy sources to use What to power with them What equipment to get How to wire it up And some wishful thinking Participants should be able to assemble their own small-scale energy-generating systems after listening. Renewable energy isn't for wealthy investors only. You can have it, too. In this talk we'll show you how to power your own stuff from the sun, wind and other sources of energy. The talk is divided into 5 different parts: A really short introduction into the available power sources like sun, wind etc. We'll show some pipe-dreams where more hacking is needed to make it work like salt-gradient energy or damming the mediterranean sea. We'll show you how much power you can expect from which source. We'll also show you what affects power output for various technologies (example: Sun needs to be shining for solar power. We'll show you how much sunshine you can expect at your place.) As a follow-up to part 2 we'll show you the amount of power various things need. You can do the math yourself afterwards to see what you can power from your balcony. Building the system, the easy and fully-legal way: Build your own independent grid with optional storage. We'll show what you need for a small-scale solar system independent of the power network. Works well for caravans, camping, gardens and allotments. There will be real solar panels on stage. You will see schematics, parts lists and instructions. We'll give some hints where to aquire the necessary stuff without paying too much. The difficult way: Put your own power into the public grid. We'll show you what you need to do this. This can either make your purse fill up automatically (big installations earning feed-in tariffs) or it can (in theory) make your electricity meter go backwards - but that's not actually allowed. Once the electrical company recognizes what you are doing (and German law requires you to tell them) unfortunately they will install a digial meter. Digital meters will not count backwards like the Ferraris counters do now... The speakers have built and are operating various small-scale power systems and come from an engineering and commercial background.
