Off Grid Living, is it possible?

No such thing as off grid. Short of joining one of the few remaining Hunter Gatherer peoples in the planet, you are gonna be locked in to some aspect of the global economy and the fossil fuel system. Living in a van? Fossil fuels. Living on a boat (thass me btw) ? Fossil Fuels. Living on a small holding, even with full solar electricity? Still locked into "the system" via your vehicle (cos you live in the country), your Council tax, probably your water bill etc. And, at the first hint of a toothache, you'll be straight round the dentist. By all means, simplify your life. Consume way less. Produce as much of your own food and energy as you can (bloody hard work btw) and develop a range of skills. But don't kid yourself.
