On December 14, the National Renewable Energy Laboratory, or NREL, announced that it had confirmed an efficiency rating greater than 41 percent for solar cells made by Durham, North Carolina-based Semprius.

Those looking to finance energy efficiency improvements, but uncertain which programs offer the best opportunity, could do no better than reading Joel Freehling’s white paper published by the American Council for an Energy-Efficient Economy (ACEEE), a nonprofit dedicated to advancing energy efficiency as a means of promoting economic prosperity, energy security and environmental protection.

Siemens AG (NYSE: SI) said this week its U.S. division Siemens Energy will supply power equipment and long-term service to PacifiCorp’s proposed 637-megawatt (MW) Lake Side 2 combined-cycle gas-fired power plant at Vineyard, Utah, 30 miles south of Salt Lake City. Financial terms of the deal were not disclosed.

A consortium of Siemens Energy, a division of German-based Siemens AG (NYSE: SI), and Prysmian Cables & Systems, a division of Italy-based Prysmian SpA (Milan: PRY.MI), has won a $400 million turnkey contract to design, supply and install a HVDC (high-voltage direct-current) link to connect the power supply networks of New Jersey and New York, the companies announced today. Construction has begun and the link is scheduled to come on line in the summer of 2013.

Siemens AG (NYSE: SI) said today it is shipping 22 wind turbine nacelles and hubs manufactured at its Hutchinson, Kansas, plant to a Puget Sound Energy (PSE) wind farm in Washington state by rail -- which will reduce the carbon footprint of the transport by 80% compared with shipping the huge 87-metric-ton components by truck.
