5. 0 kilograms of water. Today's concentration of carbon dioxide, 360 parts per million, is 100 parts per million higher than it was in 1800. Using the size of the earth and the mass of the atmosphere this computes to 520 teragrams of carbon dioxide added to the atmosphere since 1800. The experts tell us that only about half the carbon dioxide produced from fossil fuels can be detected in Griffith, Edward D. , "World Coal Production", Scientific American, Vol. 240, No. 1, January 1979, Page 38 Editors "Storm in a Precious Teacup", The Economist, web site for August 2, 2001 Drennen, T.

1 shows that the wind farms produced a significant amount of energy. The pace of construction of windmills has increased faster than that of solar energy plants because wind power is costs competitive in some situations. All of these systems are coupled with a robust base load system. Thus, disadvantages of intermittent operation and unreliability of the wind as an energy source is not a large penalty. They have also demonstrated that large windmills produce a powerful very low frequency sound that is extremely irritating.
