As the world's fossil fuel resources are  being depleted,  a new form of sustainable energy will be needed in order to ensure that Earth's people will prosper in the future without the aid of fossil fuels. Biogas is generated from anaerobic digestion of organic matter and can be economical on a small scale. Alkane Energy is a company that is currently trying to harness energy from methane seeping from old coal mines as well as installing many anaerobic digesters all over the UK in the next few years. By using biogas as a form of energy and as a way to manage food waste, sustainable energy can be produced and emissions from fossil fuels and landfills can be avoided.
