Energy content of biofuel Energy content of biofuel The Energy content of biofuel is a description of the potential energy contained in a given biofuel, measured per unit mass of that fuel, as specific energy, or per unit of volume of the fuel, as energy density. A biofuel is a fuel, produced from living organisms. Biofuels include bioethanol, an alcohol made by fermentation—often used as a gasoline additive, and biodiesel, which is usually used as a diesel additive. Specific energy is energy per unit mass, which is used to describe the energy content of a fuel, expressed in SI units as joule per kilogram
Scientific method and religion Scientific method and religion Some controversies exist over the relationship of scientific method to religion. For example, some dispute to what degree scientific method had its origins in Christian theism, or to what degree the scientific method as understood in the 21st century is compatible with religion. In the 18th century, the birth of the scientific method was largely credited to the work of Francis Bacon, Isaac Newton, and John Locke. Modern history suggests that much earlier figures such as Roger Bacon and Islamic scientists also played an important role in shaping the experimental method. Thomas Jefferson wrote "Bacon, Locke
