Victoria's Green Matters 28th May 2016
Many of us have decided to choose the ‘green option’ for our electricity supply and will now welcome the chance to opt for a carbon neutral gas supply. If you have your electricity from a supplier who offers 100% renewable energy, you may soon be able to enter into a dual fuel contract where your gas supply comes from biogas, produced by anaerobic digesters.
As emissions from energy use are one of the main causes of global warming, the obvious way to cut your carbon footprint is to opt for the best renewable energy deal on offer. We can all do our bit to reduce our reliance on fossil fuels and domestic gas use accounts for around 26% of most people’s carbon footprint.
There are now 200 anaerobic digestion units in operation all around the country where waste products are turned into gas which can be piped into the gas grid for direct use by domestic customers or it can be burnt to produce electricity which goes into the national grid. Anaerobic digestion is the breakdown of organic matter by micro-organisms in the absence of oxygen, delivering a methane rich gas for fuel and a digestate, a source of nutrients which can be used as a fertiliser. All manner of waste products from cow pats, waste food or grass from marginal farmland can be used.
This option for gas production gives us an ideal and less dangerous alternative to fracking for shale gas and also makes excellent use of waste products.
