In the dark old days before household utilities, the internet and fast food, people had simple, sustainable lives. It was called living.
In today's society it's hard to visualise life without a smart phone, but there are thousands of people in Britain who have turned their backs on modern society and live off grid.
Some do it for ideological or health reasons, others for privacy or to save money on household bills, but just how easy is it to do in reality?

3. What you need
Just how far off the grid you go is optional. For some purists it's all or nothing. For others, it's just about tapping into a renewable energy supply.
One of the biggest hurdles in Britain is finding affordable, suitable land and overcoming local planning restrictions. A residential dwelling for instance may not be allowed on the land you've purchased. Ideally your land would be near woodland for a ready supply of wood and a natural water source.
There are a number of ways of generating energy such as solar, hydro and wind. In the UK most people opt for a combination of the three. The tricky part is storing it in order to power larger electrical appliances. A few companies have now created batteries that can power homes which could change the way we live in the future.
Luckily in Britain we have a plentiful supply of water in the shape of rain which can be collected and stored for drinking, washing, cooking, cleaning and waste management. Depending on where you live, you may also have access to a local river or stream.
While nature can provide much of what we need for free, there are still some costs associated with living a low carbon lifestyle but some people have managed to save as much as £11,000 per year.
- Time - it takes a lot of time to grow your own food organically and to keep things running smoothly.
- Wood - unless you have a forest nearby, you'll need to buy in wood from somewhere.
- Power - wind turbines, hydro-electric power, solar panels and wood burning all require an initial outlay of money and then maintenance.
5. Powering down
Going off grid means you'll need to manage on around a quarter of the electricity you currently use. Which of these appliances do you think uses the most power?
