Each type of generation capacity ( Wind, Solar, Coal, Natural Gas, Nuclear, Peat, etc.) has it's own 'impacts'. There are already a number of sites out there which provide various data, some via Web mapping Services. The 'impact' is rarely evenly distributed because of wind patterns, hydrology, terrain, etc. For instance, coal gives off particulates, see http://disc.sci.gsfc.nasa.gov/oceancolor/additional/science-focus/locus/index.shtml/air_pollution.shtml and http://disc.sci.gsfc.nasa.gov/oceancolor/additional/science-focus/locus/air_pollution.shtml#google For free GIS, I heartily recommend: "Quantum GIS (QGIS) is a user friendly Open Source Geographic Information System (GIS) licensed under the GNU General Public License.
