Energy Options

Similar to Professor McAllister's approach to nuclear energy in the classroom, I typically tell students in my energy and environmental law classes that there is no silver bullet in energy and that a range of fuel sources is necessary to satisfy the world's ever expanding demand for energy.  As the tragedy in Japan unfolds, a host of "energy portfolio" questions will continue to emerge.  Should nuclear energy continue to supply about nine percent of America's primary energy needs (and approximately twenty percent of U.S. electricity production, as Professor Davies observes below)?  What are the alternatives?  How dangerous are fossil fuels as compared to nuclear energy? 

No matter the answer to these difficult questions, it is still clear that there is no silver bullet.  If we move away from nuclear, the alternatives also pose substantial concerns.  This week, for example, the EPA highlighted the dangers of coal in proposing national standards on toxic emissions from coal-fired power plants (in response to a court order).  In announcing the standards, Administrator Jackson emphasized the devastating health effects of coal, such as asthma and nervous system damage in the young.  The EPA estimates that the health and economic benefits from these new standards will be $140 billion annually and that the standards will prevent as many as 17,000 premature deaths and 11,000 heart attacks annually.

Natural gas, which is often touted as the clean alternative to coal, other fossil fuels, and nuclear, also has risks, as highlighted in my last post.  In addition to concerns about chemicals and radioactivity levels in wastewater from hydraulically fractured wells, explosions of natural gas pipelines -- some deadly, and others not -- in Minneapolis, Allentown, and San Bruno remind us that no energy option is perfect. 

To end on a point of optimism, however, it is encouraging to see the continued, albeit slow, expansion of renewable energy in the United States. As the Energy Information Administration observes, "Wind power has been the fastest-growing source of new electric power generation for several years," and U.S. shipments of photovoltaic cells and modules skyrocketed in 2009.  Like any other energy source, renewables will not solve all of our problems, but they are a highly promising energy option. Building from the observations about energy planning in the post by Professor Davies below and Professor McAllister's points about energy efficiency, let's hope that as Americans mourn Japan's tragedy and reflect on our own energy options, we will be creative in contemplating an improved global energy future.
