The solar cells found in today’s typical photovoltaic (PV) solar panels convert about 20% to 23% of the light that passes through them into electricity, leaving nearly 80% of the their possible energy conversion behind. Thus, improving solar cell efficiency is always an important topic for PV researchers. Normally made from silicon, scientists believe that using different materials or a combination of materials could be a major key to boosting energy conversion and improving efficiency in solar cells.
As president of Queen City Forging, a metal components supplier for more than 120 years, he was struggling to remain competitive. In 2004, CEO Rob Mayer drew a majority of his revenue from manufacturing metal parts such as horseshoes and sewing machine rocker arms–but business was declining and his machinery was getting old.
National Lab-Industry Partnership Develops New Technology, Surpasses DOE Efficiency and Cost Goals
Home heating is the largest energy expense for most U.S. homeowners and accounts for nearly 30% of energy used in the nation’s residential buildings. Millions of homeowners in colder regions of the country do not have natural gas available, leaving furnaces to be fueled with heating oil, propane, or electricity. This can often result in higher heating bills for homeowners.

The U.S. Department of Energy (DOE), U.S. Fish and Wildlife Service (USFWS), and Ohio Environmental Protection Agency (Ohio EPA) are working with a local land trust organization to acquire conservation easements within the Paddys Run watershed. Funds for this effort are provided from a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) natural-resource damage settlement. DOE and Ohio EPA settled their claim in November 2008. As part of the settlement, DOE paid $13.75 million to compensate for natural resource injury.
Cooper Tire recently developed concept tires that can improve fuel efficiency by 5.5%, supported by a project from the EERE Vehicle Technologies Office (VTO). In addition to exceeding VTO’s goal of improving fuel efficiency by 3%, the new tires are more than 23% (5 to 6 pounds) lighter than current tires. They also reduce rolling resistance by more than 30% while still meeting performance and durability goals.
