Enormous resources of other fossil fuels exist, but they are not yet in large-scale commercial use. Examples of fossil fuels not used currently, but potentially useful in the future, are oil shale and tar sands (see Chapter 10). The relative value of the common fuels is stated in quantities as follows, but this is of course dependent on the quality of the coal and the gas.

of fossil fuels. The Carbon Cycle The fossil fuels used as energy sources today are coal, petroleum and natural gas. Enormous resources of other fossil fuels exist, but they are not yet in large-scale commercial use. Examples of fossil fuels not used currently, but potentially useful in the future, are oil shale and tar sands (see Chapter 10). Fuels are also used in the cells of organisms in a process known as cellular respiration, where organic molecules are oxidized to release usable energy. Hydrocarbons and related oxygen-containing molecules are by far the most common source of fuel used by humans, but other substances, including radioactive metals, are also utilized.

Metal Finishing Processes Spacing Figure Features of Surface Texture Surface Roughness It refers to small, finely spaced deviations from nominal surface that are determined by the material characteristics and the process used. Waviness It is defined as the deviations of much larger spacing occurring due . sources of energy, origins of the power used for transportation, for heat and light in dwelling and working areas, and for the manufacture of goods of all kinds, among other autoinsurancequotesv.info development of science and civilization is closely linked to the availability of energy in useful forms. Modern society consumes vast amounts of energy in all forms: light, heat, electrical, mechanical. A fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis. The age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds million years.
