eh, it could be steam, but it looked darker than steam from the road. even with things such as that, cars still get all the attention. you never hear anyone talking about pollution unless its coming out of a cars exhaust. thats what bothers me. you have all these people saying how we need 35 mpg cars and whatnot, but you dont hear anything about anything else, when there are other problems, not only cars. what im saying is, dont focus on one aspect of it, look at the big picture. more things pollute than cars, and they pollute more and well.
Part of that problem is the "out of sight, out of mind" mentality that comes with electricity. No one gives a hoot how it's made as long as the lights come on when they flick the switch.
Yes, it's stupid to blame it all on cars, no one said we were the smartest bunch on the planet.

It's easier to target cars than it is a power plant, although I don't understand why. I'm in favor of more nuclear power plants, passive solar shingles on homes and wind power.
Here in Iowa, along the I-35 corridor, we have quite a few wind farms, we're actually 4th in the Nation for the number of turbines at 1,273 MW, and we're putting up more. Here's what we have so far:
Nuclear Generating Plant
Duane Arnold Energy Center..............Palo
Hydroelectric PlantsFive-In-One Dam........Cedar Rapids
Iowa Falls Mill............Iowa Falls
Keokuk Dam...............Keokuk
Anamosa Dam............Anamosa
Waverly Mill..............Waverly
Amana Dam................Amana
Ottumwa Dam............Ottumwa
Maquoketa Dam.........Maquoketa
Coal-burning Plants: Bettendorf, Cedar Falls, Cedar Rapids, Chillicothe, Council Bluffs, Dubuque, Lansing, Sioux City, Montpelier, Marshalltown, Waterloo, Spencer and Mt. Pleasant.
Iowa currently has more than 600 wind turbines, producing enough electricity to power 140,000 homes.
So yeah, we've made some progress, but I wouldn't mind seeing half of those 13 coal plants being closed down. I approach the green lifestyle as a way to save myself some money. Tankless water heater, light tubes in rooms with no windows, CFL's, doing the laundry in cold water, using the dishwasher for 2 days worth of dishes instead of once a day...it all helps, and it saves
me money. Reduced coal burning is just a side effect.
Update:
In late September 2007, Siemens Power Generation celebrated the grand opening of its new wind turbine blade factory in Fort Madison, Iowa, on the banks of the Mississippi River. The 311,000-square-foot (28,900 m²) factory is expected to produce 600 wind turbine blades each year and should employ 260 people by year's end. The facility manufactures 148-foot-long, 12-ton blades for the company's 2.3-MW wind turbines installed in the United States. In October, Iowa Governor Chet Culver announced that Hendricks Industries plans to build a manufacturing plant for wind turbine towers in Keokuk, which is also on the Mississippi River. The 347,000-square-foot (32,200 m²) facility will employ 350 people, and the company will also employ 22 people at a project to expand the city's port.
