BioGas - The Energy of Our Future

Page 1 of 5
Ten years ago gasoline prices were around $1.00 and there was plenty of oil. Now gasoline is reaching the $5.00 mark, the population has grown to an outrageous amount and landfills are filling to the point that they must be closed. Many forms of energy we use in our homes and cars are not being replenished. Fossil fuels took millions of years to create. They cannot be made over night. There are finite or limited amounts of these non-renewable energy sources. That means they cannot be renewed or replenished. Once they are gone they cannot be used again. We must all do our part in saving as much energy as we can. Scientists are researching alternatives to oil, coal and natural gas because those resources are dwindling and damaging the earth. An alternative to these fuels is Bio Gas. Bio gas has become appealing because it has the capability to generate energy from organic waste. Organic waste is plentiful and widely accessible. Everyday food waste, human and animal waste, and crop waste can be used to produce Bio Gas. Bio Gas can improve standards of living economically and socially, protect natural resources and is inexpensive to produce and maintain. According to Curry and Pillay, the first anaerobic digestion plant used to turn waste into energy was built in 1859. Although there is note of the process occurring in much earlier times, the first was built in Bombay, India. Since then, it is surprising how widely used this process is. Bio gas systems can be found in Africa, India, Germany, Denmark, Austria and the United States (201). Amweelo reports, Bio Gas is a combination of methane and carbon dioxide. The methane and carbon dioxide are produced when bacteria forms on vegetables or organic materials in airless conditions called a vacuum. The process is also known as anaerobic, or without air, digestion. Amweelo says, fossil-based fuels are getting low, becoming more expensive and causing carbon dioxide emission levels to increase.
