I don't really get how poeple on the side against changing energy policy get so much wind in their sails. First off it's outrageous to think that we have absolutely zero impact on our environment or that the results of our actions are immediately perceptible. Even if there were no theory about man-made global warming I would still be concerned about the impact of any changes to our environment.
Second it's clear that enivornmental impacts of fossil fuel extraction and usage seem plenty detrimental to me, global warming or no. Ripping up the landscape for coal mines, massive coal ash spills, oil slicks wiping out wildlife and poisoning the water, acid rain, and so on... all those things suck a pretty big dick on their own without even worrying about the temperature of the earth.
Then you have the potential to get the fuck out of the middle east and let that place implode when the oil money stops coming, I would think most conservatives would like the idea of that... I just don't really see on any level why leading the world towards a green economy would be a bad thing, especially when our bigger political/economic adversaries tend to still be manufacturing countries who will be more adversely impacted than us.
It's a cost and control issue, really.
I think that nearly all Americans (namely, everyone other than those employed by old energy interests, such as employees of oil companies) would love to have clean, affordable, and self-sufficient energy solutions. However, the proposed "green" solutions (wind turbines, geothermal energy, solar, hydroelectric) are limited and costly. The two big green energy sources, wind and solar, are significantly more expensive than fossil fuels per unit energy. So, from a cost perspective, there is no benefit to consumers in switching now, as increased energy costs would lower the standard of living for millions of lower and middle class Americans.
As for other sources of pollution (particularly of the personal nature), people dislike directives on how to live their lives. CFLs, for example, are an inconvenience to many people because the quality of light produced is inferior (or rather, users dislike the more sterile light of CFLs) to that produced by incandescent bulbs (particularly for reading use). Additionally, many of these "green" solutions have a high initial investment. While CFLs may save homeowners money over decades, it is difficult for lower-income families to transition to the newer bulbs. Of course, the irony of CFLs is that they pose an environmental cost greater than that of incandescent bulbs: mercury pollution. Fluorescent bulbs use mercury vapor, and heavy CFL usage guarantees that many careless residents will dispose of the bulbs incorrectly and they will end up in landfills, broken and leaking.
So, what of businesses? Simply, added restrictions and penalties will contribute to operating cost, thereby cutting profits. Reduced profits mean fewer jobs and increased costs to consumers (when government presses a company, it passes this pressure to the consumer), thereby hurting average Americans.
There are reasonable, non-dogmatic explanations as to why opposition to many environmental reforms is strong. Not everyone who opposes sweeping environmental legislation is anti-science or anti-environment. Commercial/industrial production and economic prosperity impact lives more directly than carbon emissions.
