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.
Good-paying jobs in renewable energy are important to the nation's future and don't all require a college degree, high school students learn.
The use of daylighting drives the size of the NREL's new super energy efficient Research Support Facility as well as the features of its windows.
It may come as a shock to my college math professor, but where my family's finances are concerned, I'm a budgeter. Just before a new month begins, I take some time to plan for the month's regular bills as well as any special events or holidays that might require setting some extra money...
On Monday, Amy pointed you to the great stories on the Energy Empowers Web site. Whether you're looking for stories from individuals, communities, or industry, something on the site is sure to strike a chord. So take a look at the site and tell us:
A secretive Silicon Valley startup working on a new way to produce cleaner energy is taking the wraps off its product: a huge box of fuel cells that it hopes will allow homes and businesses to generate their own electricity.
To be a global leader in the electronics industry, a component distributor must support OEMs with technical information and engineering resources, while providing global logistics and inventory services that streamline the manufacturing process.
This past month, we celebrated my little daughter's first birthday - which meant a trip from Virginia to New Jersey. Ordinarily, this isn't a major effort, but this was on the verge of the big snow storm on February 5. Naturally, we were a bit concerned about our travel prospects.
Most LCD panel and set makers are focusing on development of LED (light emitting diode) backlight units for improved visual performance, thinner form factor, and lower power consumption. The key issue has been reducing cost, in absolute terms and relative to the conventional CCFL (cold cathode fluorescent) backlights. The newly-released DisplaySearch Quarterly LED & CCFL Backlight Cost Report, which is the only report to analyze and forecast the cost structure of CCFL and LED backlight costs, disclosed that the average cost of 40” edge LED backlight unit in Q1’10 is $118, and will fall to $100 by Q4’10 (see Figure 1). Cost reduction is driven by increasing production volumes, which affects LED and material costs, and by improvement in LED luminous intensity, which enables the use of fewer LED chips.
