The United States' transition away from coal energy has begun.

Permits for new coal plants are being denied and many that were in production are being abandoned. With the Energy Department forecasting a 22% increase in power usage in the next 20 years, it is obvious that the vast majority of this increased power will come from alternative sources. This is further evidenced by the $16.8 billion of stimulus allocated for renewable energy compared to the relatively paltry amount of $3.4 billion for clean coal technologies.

Chris Morrison of BNET Energy contends that it would be wise for environmentalists to allow the construction of new plants with better emission-control technologies on the condition that older plants with antiquated technology be closed. While it is true that new plants are considerably cleaner, the general consensus is that "clean coal" technology, which includes carbon capture and sequestration, will not be readily available for at least another decade. It would be more costly to build new plants that would have to be either shut down or overhauled completely in order to implement CCS technology after just ten years. Factor in the exorbitant expense of implementing carbon capture technology and the prospect of building a coal-fired plant becomes financial suicide.

Still, despite the block against new plants, very few existing coal-fired power plants that are in operation have been shut down. With over half of the nation's energy derived from these plants, it is easy to see why.

However, once laws are enacted that impose costly fines against coal producers for carbon dioxide emissions these existing coal factories will certainly begin to diminish. As renewable energy becomes more efficient and reliable the dwindling profits of the coal energy factories will be squeezed further by the new competition.

For better or worse, the transition has certainly begun.
