![]() Wind makes less sense for the individual household. Taking into account maintenance costs, you could break even within about eight years. Solar is currently the most popular choice – a typical system to power the average UK family home would cost around £8,000. Satisfying the electricity needs of our modern lifestyles, wherever we live, is more tricky. At around £700, any saving from the gas produced would not come close to breaking even for decades, but it is a great way to produce biogas and fertiliser while dealing with waste. ![]() A home-ready anaerobic digester will turn your food waste, waste-water and sewage into enough gas to cook your meals. From dog poo to a famous London fatberg, businesses are making good use of our waste – and so can you. Going off-grid for our gas can even help us solve two problems at once. It’s also possible turn waste cooking oils into environmentally friendly biodiesel to be used as heating oil or vehicle fuel. These can be quite expensive to buy, costing several thousands of pounds but are efficient and, as a longer-term investment, will pay for themselves after several years. Solar thermal collectors and ground source heat pumps allow us to extract natural heat from our surroundings to heat water systems. In colder countries such as the UK, where the average family uses around 125 kilowatt hours a day, heating homes requires a lot of energy.īut there are many options out there to keep us warm, the simplest of which is burning biomass ( wood and other organic matter). On the US mainland, for example, it is around 30 kilowatt hours a day but in Hawaii it is just half of this. The average family’s energy consumption varies depending on where they live. The key to producing enough energy to live off-grid is to use a range of solutions.
