The production of such a vital form of energy as electricity could be made much more efficient and environmentally friendly through the use of biogas.

Currently, over 65% of the world's electricity is produced through fossil fuels powering turbines.

But experts in turbine technology have already confirmed the enormous potential of replacing fossil fuels with biogas - gas made from the breakdown and recycling of organic materials such as food waste. Let's explore some of the environmental and economic benefits that can come from using biogas as a source of electricity.

Most of our electricity today comes from fossil fuels. It is produced either through steam turbines, in which the fuel is a heating agent that boils water to create steam that turns turbines. Or the fossil fuels could be used in gas turbines, which use burning gas to turn turbines directly (without the use of water or steam).

But natural gas, coal, and other fossil fuels they all pollute the environment. Biogas, on the other hand, can be filtered of impurities so that it burns much cleaner. And not only does biogas emit less greenhouse gas into the air, but it is carbon neutral as well.

If that is not incentive enough, the potential economic impact of using biogas in electricity production certainly is. Fossil fuels are a dwindling resource, and are becoming increasingly expensive. Biofuel, however, can come from recycled biomass materials such as food waste (learn about how Regreen Technologies can help make this happen). Food waste and other organic waste materials are readily available and continuously produced commodities. Plus the cost of using biogas can be greatly reduced (and possibly entirely eliminated) by the amount savings achieved from not having to dump food waste into landfills.

Siemens, one of the world leaders in turbine technology, has already tested and confirmed that biogas is just as effective and efficient as natural gas in energy production. With its potential for providing a cleaner environment and improving the economy, it can be big stepping stone on the path to a sustainable future.
