[MassHistPres] Wind Power Bait and Switch

[katrimiller at aol.com]

I know that this question was addressed to David, but I'd like to respond with a few excerpts from the EPA website which indicate at least one way in which the reduction of reliance on fossil fuels relates to historical preservation.


Cause of acid rain


"Acid rain" is a broad term referring to a mixture of wet and dry deposition (deposited material) from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. The precursors, or chemical forerunners, of acid rain formation result from both natural sources, such as volcanoes and decaying vegetation, and man-made sources, primarily emissions of sulfur dioxide (SO2)and nitrogen oxides (NOx) resulting from fossil fuel combustion. In the United States, roughly 2/3 of all SO2 and 1/4 of all NOx come from electric power generation that relies on burning fossil fuels, like coal.  Acid rain occurs when these gases react in the atmosphere with water, oxygen, and other chemicals to form various acidic compounds. The result is a mild solution of sulfuric acid and nitric acid. When sulfur dioxide and nitrogen oxides are released from power plants and other sources, prevailing winds blow these compounds across state and national borders, sometimes over hundreds of miles.


Effects of acid rain

Acid rain and the dry deposition of acidic particles contribute to the corrosion of metals (such as bronze) and the deterioration of paint and stone (such as marble and limestone). These effects significantly reduce the societal value of buildings, bridges, cultural objects (such as statues, monuments, and tombstones), and cars.
Dry deposition of acidic compounds can also dirty buildings and other structures, leading to increased maintenance costs.

David,  
    Excuse me, because I must be dense, but how does your post relate to 
Historical Preservation.  The aspect of the impairment to views has been beaten 
to a pulp.
