Non-conventional oil Non-conventional oil is oil produced or extracted using

techniques other than the traditional oil well method. Currently, non-conventional oil production is less efficient and some types have a larger environmental impact relative to conventional oil production. Non-conventional types of production include: tar sands, heavy oil, oil shale, biofuels, thermal depolymerization (TDP) of organic matter, and the conversion of coal or natural gas to liquid hydrocarbons through processes such as Fischer-Tropsch synthesis. These non-conventional sources of oil may be increasingly relied upon as fuel for transportation when conventional oil becomes "economically non-viable" due to depletion. Conventional sources of oil are currently preferred because they provide a much higher ratio of extracted energy over energy used in extraction and refining processes. Technology, such as using steam injection in tar sands deposits, is being developed to increase the efficiency of non-conventional oil production.

The Greenhouse Effect

To maintain the Earth's temperature, energy reaching the Earth from the sun must equal energy radiated back out from the Earth. As with incoming radiation, the atmosphere interferes with outgoing radiation. Water vapour absorbs strongly in the 4-7 mm wavelength band and carbon dioxide in the 13-19 mm wavelength band. Most outgoing radiation (70%) escapes in the "window" between 7-13 mm.

If we had no atmosphere, as on the moon, the average temperature on the Earth's surface would be about -18°C. However, a natural background level of 270 ppm CO2 in the atmosphere causes the Earth's temperature to be about 15°C on average, 33°C above the moon's.

Human activities are increasingly releasing "anthropogenic gases" into the atmosphere, which absorb in the 7-13 mm wavelength range, particularly carbon dioxide, methane, ozone, nitrous oxides and chlorofluorocarbons (CFC's). These gases are preventing the normal escape of energy and are expected to lead to an increase in terrestrial temperature. Present evidence suggests "effective" CO2 levels will double by 2030, causing global warming of 1~4°C. This would lead to changes in wind patterns and rainfall, with the possible drying out of the interior of continents and oceans rising by as much as 30 cm. Further increases in the release of anthropogenic gases will, of course, cause more severe effects
