The statistics vary, but all seem to be in agreement that nearly 30 to 40% of the present load base on the grid is caused by induction motors
The race to build a better solar cell is looping through the National Renewable Energy Laboratory where new robots are fabricating thin-film cells and analyzing glitches faster and with more precision than ever before. How much faster? The robot working with silicon can build a semi-conductor on a six-inch-square plate of glass, plastic or flexible metal in about 35 minutes.
Boston and New England businesses are again being recognized by EPA’s Energy Star program for their commitment to save energy and money through energy efficiency. Continuing the impressive growth of the past several years, in 2009 nearly 3,900 commercial buildings nationwide earned the Energy Star label...
Today, the U.S. Department of Energy announced it had issued subpoenas to three companies who were identified as selling certain torchiere lamps that failed to meet federal energy efficiency standards.
US Department of Energy Secretary Steven Chu and US Department of Interior Secretary Ken Salazar announced today that the two agencies, along with the Army Corps of Engineers, will cooperate more closely and align priorities to support the development of environmentally sustainable hydropower.
Cree, Inc. (Nasdaq: CREE), a market leader in LED lighting, announces that its high brightness LEDs are used in Lighthouse Technologies' high definition video screens installed this season in the American Airlines Center, the Dallas home to both the NBA's Mavericks and NHL's Stars.
On Tuesday, Amy pointed you to some resources that will help you learn more about your state's energy profile. Check out some of the resources she mentioned, and tell us:
Fort Sam Houston received 20 Neighborhood Electric Vehicles (NEVs) in January as part of a larger plan to replace petroleum-based DoD vehicles with more “energy-efficient” transportation. The Army plans on replacing up to 28,000 gas-powered ground support vehicles with electric vehicles at more than 155 Army installations worldwide.
An Energy Empowers story that was recently highlighted on the EERE home page detailed Kentucky's efforts to improve the energy efficiency of its buildings and generally curb the state's "energy appetite." The story caught my eye as I was born and raised in Kentucky's capital, and I still...
High throughput system can analyze enzymes, poplars, switch grass, thousands at a time to help determine which plants are best suited for biofuels.
NREL's new Open PV Web site lets users download information about installations, explore trends in photovoltaic markets.
This week, John told you about his experience with window shades that improve the energy efficiency of his windows. There are several things you can do to improve the efficiency of existing windows, including adding storm windows, caulking or weatherstripping, or using window treatments.
As I mentioned in yesterday's blog, I had insulated window quilts installed on most of my home's windows. I should have bought window quilts for all of our windows, but I refrained from doing so on two downstairs windows to save money (which, in the long run, I didn't). There were window...
There's a lot of talk these days about installing new energy-efficient windows. Thanks to a Federal tax credit of up to $1,500, window advertisements, both print and radio and TV broadcasting, are aplenty. I don't want to knock energy-efficient windows. There are some great window...
Powertraveller has released the ultimate travel charger for on-the-go professionals, outdoorsmen, and techies alike—the powermonkey-eXplorer. With three charging methods, international adapters, and tips for nearly every portable electronic device, you’ll never be somewhere without power.
On Monday, Andrea pointed you to the redesigned EERE home page. While this blog usually focuses on resources from EnergySavers.gov and other sites that are specifically for consumers, we know that many readers are interested in broader energy efficiency and renewable energy information....
The emergence of energy-efficiency standards and continued evolution of processing and feature sets to support new products that consumers/enterprises use in everyday life: DVRs, set-top boxes and modems, industrial handhelds, portable media players, bar-code scanners have changed the methodologies employed for addressing DC power conversion, management and distribution.
The OSTAR Compact LED from OSRAM Opto Semiconductors has been developed specifically for use in vehicle headlights. This high-power LED is designed for Daytime Running Light (DRL) applications based on the use of light guides.
Solar energy has been called the wave of the future. MacroAir Technologies, a company founded on the very principal of innovation, is surfing that wave with the introduction of the MacroVoltaic fan. Receiving the highest certified rating, the MacroVoltaic fan is the only solar high volume low speed (HVLS) industrial fan on the market.
I have a love/hate relationship with buses. I love that they save me gasoline, are more efficient than driving a car, and reduce my greenhouse gas emissions. However, I hate them when they're running late! But there is one category of buses that I'm particularly fond of – those that...
The freshest energy news on the block this week is the newly designed eere.energy.gov. In case you haven't visited the site lately, the EERE site contains in-depth information about the U.S. Department of Energy's office of Energy Efficiency & Renewable Energy.
On Monday, Amy discussed how she keeps track of her energy costs and uses past bills to plan her budget for the coming months. Her utility has a useful tool that helps with her planning. If your utility doesn't offer a similar service, you might try using ENERGY STAR's Home Energy Yardstick.
This winter has seemed like an especially long one to me. I'm ready to wear shorts and enjoy nice, long summer days. Alas, the reality is that it will probably be cold for at least another month here in Washington, D.C. All that cold air robs not only our jacketed bodies of warmth, but it...
NREL biologists test revegetation and wildlife protection strategies at new solar power array at the National Wind Technology Center.
