Revised Navy Energy Policy

On July 10, U.S. Navy announced a new shore energy policy. A complete revision from the previous energy policy published in 1994, the Shore Energy Management Instruction codifies the Navy's strategy to ensure energy security meets federal mandates and executive orders and achieves Department of the Navy (DoN) shore energy goals.

The new policy is necessary, according to the Navy, because naval forces require constant support from shore installations. The Navy wants to mitigate its vulnerabilities related to the electrical grid, such as outages from natural disasters and man-made events, by lowering consumption, integrating renewable energy sources, and increasing control of energy supply and distribution. Energy reliability, resiliency, and redundancy are essential components of the Navy's Critical Infrastructure Protection program.

The revised policy includes specific responsibilities and actions that shore personnel must take in implementing the Navy Shore Energy program. Each Navy installation will have a tailored energy consumption reduction goal based on its unique energy situation. By increasing energy efficiency, the Navy hopes to reduce operating costs, multiply the impact of current and future alternative energy sources, and achieve renewable energy targets.

Report On Use of Carbon Capture & Storage (CCS).

The Congressional Budget Office (CBO) has released its report examining the nation's use of carbon capture and storage (CCS). The report, titled “Federal Efforts to Reduce the Cost of Capturing and Storing Carbon Dioxide,” concludes that the initial costs of generating electricity with CCS would be “much more expensive than electricity produced by conventional coal-burning plants.”

According to the CBO, coal-fired power plants produce up to 45% of the usable electricity in the US, but they also account for a third of all U.S. emissions of carbon dioxide (CO2). CO2 is a major component in greenhouse gases, which have been associated with climate change. CCS is considered one option for coal-fired power plants to reduce their carbon emissions by “capturing” the CO2 produced when coal is burned, compressing it into a fluid, and storing it deep underground.

Although the process is in use in some industries, no CCS-equipped coal-fired power plants have been built on a commercial scale. Since 2005, lawmakers have given the Department of Energy (DOE) almost $7 billion to develop CCS technology, including its commercial viability, and reduce the cost of electricity generated by CCS-capable plants. The CBO concludes that unless funding to the DOE is substantially increased, or other policies are adopted to encourage utilities to invest in CCS, federal support is likely to play only a minor role in deployment of the technology.

Draft Nanomaterial Case Study Released For Comment

On July 2 , 2012, EPA announced a 60-day public comment period for EPA's case study on multiwalled carbon nanotubes in flame-retardant coatings used in upholstery textiles. The draft document on the study, issued by EPA's National Center for Environmental Assessment (NCEA), does not draw conclusions regarding potential risks or hazards of multiwalled carbon nanotubes; rather, it aims to identify what is known and unknown about the nanotubes to support future research. EPA says the draft document, which is being released for public comment and peer review, is not final. The Agency will consider comments it receives when finalizing the case study. In addition, EPA will hold an information exchange meeting to discuss the draft document and to provide information on the nanomaterial case study.

According to EPA, the draft document follows previous efforts on engineered nanoscale materials, or nanomaterials. Nanomaterials are materials that measure between 1 and 100 nanometers and often possess unusual, if not unique, properties that arise from their small size. Like all materials, EPA says, nanomaterials offer the potential for both benefits and risks.

EPA's 2007 Nanotechnology White Paper included the following recommendations regarding the risk assessment of nanomaterials:

1.  Develop case studies based on publicly available information on one or several intentionally produced nanomaterials and identify information gaps to help map areas of research that would support the sick assessment process; and
2. Hold a series of workshops involving a substantial number of experts from several disciplines to assist in these processes.

To meet these recommendations, NCEA has also prepared the Nanomaterial case studies “Nanoscale Titanium Dioxide in Water Treatment and in Topical Sunscreen” [Final] in 2010, and “Nanoscale Silver in Disinfectant Spray” [External Review Draft] in 2012.

The comment period for the draft document begins July 2, 2012, and ends August 31, 2012. The public information exchange meeting will be held on October 29, 2012 at the EPA facility in Research Triangle Park, North Carolina.
