Move Over MPG, There’s a New Way to Measure Efficiency

Wh/kg is the new way to measure efficiency for vehicles; well, EVs and hybrids at least. Wh/kg stands for watt hours per kilogram, and it is a measurement of energy density. Essentially, the higher the Wh/kg number, the more energy-dense the battery. Energy-dense batteries can be smaller and lighter, and thus hold great potential forRead… Read more »

Green Building Skills Training Funding Announced

At the end of last week, the DOE and Commerce Department announced that they had teamed up to provide $1.3 million for green building skills training through the Department of Commerce’s National Institute of Standards and Technology (NIST) Manufacturing Extension Partnership Program. The funding is intended for training programs that will increase energy efficiency, reduceRead… Read more »

EIA Predicts Future U.S. Electricity Mix

A few days ago, the EIA published its Annual Energy Outlook 2012 Early Release. In the Outlook, the EIA looks at past energy trends (1990-2010), considers current law and subsidies, and then predicts the future energy mix for the nation’s electricity. The graph above shows that they expect renewables to grow, but for coal toRead… Read more »

Energy Company Takes the Plunge on Wave Power

Wave power is one of those technologies that has yet to come of age, but that many believe holds great promise. Now, across the pond, one company has decided to give it a try. Ecotricity, a UK-based company that has traditionally built wind turbines, is now developing Searaser, an invention that “harnesses the almost constantRead… Read more »
