Why discuss what a wind farm looks like? Take a look on Google Earth or one of the other global view sites.

Clean energy progress so far:

IPCC data says in 2004 the world used 468 Exajoules of energy. So far, man's worldwide efforts over the last 20+ years to produce clean energy from wind, solar, geothermal, etc., add up to about 1/2 of one percent (2.4/468 EJ - see 2004 .pdf). That's practically nothing. Certainly not enough to get us out of Global Warming trouble. Clean power from carbon-neutral biomass, hydro and nuclear was 89.6/468 EJ or 19% of the world's energy. The remaining 80% are CO2-producing fossil fuels.

Above about 6%, wind and solar tend to de-stabilize electrical grids.
