The debate over global warming has become nauseating. On the one hand, some on the political right call man-made global warming believers "alarmists" and "religious cultists", while many on the left compare the act of questioning this theory to denying the Holocaust.
It would be infinitely more constructive if we all spent less time insulting people without our particular views and more time trying to find common ground. For starters, the goal of many on the left is to reduce the impact on the earth by either reducing the usage of energy, or changing the method of energy production. It is not, to my understanding, a goal of simply finding new ways that the government can regulate our lives. For many on the right, there is a strong belief that government regulation is a problematic solution to most issues, which cuts to the core of why there is a lot of resistance. Conservatives aren't fighting for the excuse to pollute the earth, they just don't want government regulation that could cause extensive economic damage.
We should all be looking for market solutions to this problem, whether or not we have the government involved. To be more precise, if a new technology is on the market which reduces our impact on the environment AND it is economically beneficial - both sides should embrace it. A lot of discussion has focused on ethenol, solar and wind power, but I rarely hear about geothermal energy. I think this is a home heating / cooling technology that already can meet the concerns of capitalists and environmentalists alike.
To grab your attention, here is a brief section of of a report released on January 22, 2007, by an MIT-led interdisciplinary panel:
Geothermal energy from EGS represents a large, indigenous resource that can provide base-load electric power and heat at a level that can have a major impact on the United States, while incurring minimal environmental impacts. With a reasonable investment in R&D, EGS could provide 100 GWe or more of cost-competitive generating capacity in the next 50 years. Further, EGS provides a secure source of power for the long term that would help protect America against economic instabilities resulting from fuel price fluctuations or supply disruptions (M.I.T., 2007, p. 1-3).
Here is a comparison of some of the aforementioned environmental aspects:

(World Energy Council, 2007)
In addition to large scale energy production, geothermal systems can be installed in residential homes. These systems can reduce the heating/cooling portion of an energy bill for a home by 75%. In addition, at certain times of the year, the geothermal system will heat water, which reduces the energy required by water headers. The economic issue is that the upfront costs are prohibitive for existing homes to "retrofit". However, the cost for installing these systems in a new home construction will be offset by the ongoing reduction of the energy bill. It is estimated that after seven or eight years, the homeowner will begin seeing the economic gain.
Wait - seven years? That's a long time! This is the main reason this hasn't taken off in the United States. While many states (and the federal government) are giving tax breaks for energy efficient windows and solar panels, not many have even given a thought to this technology.
I encourage a brief perusal of the Department of Energy's overview of this technology: http://www1.eere.energy.gov/geothermal/overview.html.
