Alternative Energy Potentials of Biogas
In just the past one hundred and fifty years, humans have entered onto a path drastically different than anything we have known in the past. We have developed and embraced modern technologies, and with these a new way of life. This boom in new technologies has been driven and made possible by energy in the form of fossil fuels. Fossil fuels come from plant and animal matter deposits that are millions and millions of years old. They have very high-energy potentials (one pound of coal contains 13000 Btu (Ristinen 1999), and therefore are excellent for our needs. The most utilized of these forms are coal, petroleum and natural gas. All over the world fossil fuels are being extracted at a faster and faster rate as the world's energy demands increase. This presents a large problem because fossil fuels are not renewable within a practical timescale, since they take millions of years to form. According to estimated calculations based on current......
