Energy harvesters do not necessarily make sense in all potential applications where a battery is replaced. Battery technology is continuously advancing and due to volumes achieved, the price points reached are at levels where harvesters cannot compete.
This week, we discussed how consumers are financing solar energy systems and the new PowerSaver pilot loan program, which will help consumers finance energy-saving improvements for their homes. When making home improvements, cost is almost always a consideration, and sometimes upfront...
Straw that farmers would normally leave to rot or simply burn is now being turned into second-generation biofuels. At the landmark Inbicon plant in Kalundborg, Denmark, Innovation magazine shows how the newest developments in enzyme and processing technology...
For anybody who has heard about the many benefits of upgrading your home with an energy efficient water heater or furnace - or has wanted to make simple energy-saving home improvements such as insulating their attic, sealing their ducts, and installing better doors and windows - there may...
Editor's Note: This entry has been cross-posted from DOE's Energy Blog.
New 3 megawatt machine towering over the National Wind Technology Center could lead to more reliable turbines, less expensive power.
April has been a busy month for Energy Savers! The biggest draw was Earth Day, which we celebrate all month on the blog and website. Here's a recap of April along with a few other tidbits:
If these electric vehicles can survive in Antarctica, they could help establish a fleet to offset fossil fuel use in an environmentally sensitive research area.
XP Power launched its AHM Series of external AC/DC power supplies aimed at a broad range of medical and IT applications. The series comprises five single-output ranges of 85-, 100-, 150-, 180- or 250-W output, and provides the popular nominal outputs from +12 to + 48 VDC.
On Monday, John discussed leaky ducks…err…ducts, and how and why you should make sure they are well-sealed.
This past Friday marked the 41st Earth Day. The past 40 years have demonstrated the growing global green movement, reinforced each year by Earth Day to celebrate and spread awareness of environmental protection and sustainability. Earth Day’s goals of environmental protection and sustainability are echoed by the EcoCAR Challenge, its organizers, participating student teams, and sponsors.
Power-One was the PV inverter market’s largest share gainer in 2010, moving up to second in the global rankings according to IMS Research’s latest report on the market. The report will also reveal that for the first time all of the top 10 suppliers to the market in 2010 were European...
ZemosLED has announced the US launch of the patented, 80,000 hour Zemos9090 LED package. The Zemos9090 has seen extensive use in the company's own line of lighting fixtures with extended lifespans, but has not previously been available to third parties as a discrete component.
Tomorrow is Earth Day! We've already written about how you can resolve to make Earth Day last all year, and ways you might encourage your coworkers to save energy for Earth Day. Now that the day is almost here, tell us:
Happy Earth Day! Today, April 22, marks the 41st anniversary of Earth Day. Check out these resources from the Department of Energy to help you celebrate, get in the Earth Day spirit, and take action:
One of the DOE building experts I worked with back in the early 1990s stated that a major energy problem facing the nation was leaking ducts (although it sure sounded like "ducks"). He was referring, of course, to the ductwork that most of our homes have to distribute the hot air in...
Two forthcoming events in Germany reflect the intense interest in energy harvesting for electric vehicles. Energy Harvesting & Storage Europe 2011, 21-22 June covers many forms of harvesting for other applications as well and drills into the technology...
The smart meter market is projected to grow by double digits over the next several years as consumers upgrade from traditional electromechanical meters. Smart meters use the latest integrated circuit (IC) technology to accurately measure and report the amount of power consumed.
Since the smart grid was first implemented in Italy in 2005, municipal governments in American cities, such as Austin, TX and Boulder, CO have started switching to smart meters in order to save energy, reduce costs and increase reliability and transparency.
International Rectifier today introduced the IRS2548D Switched Mode Power Supply (SMPS) control IC for energy efficient applications for high power Light Emitting Diode (LED) illumination including LED street lighting, stadium lighting and theatrical lighting.
Compu Dynamics, LLC (www.compu-dynamics.com) today announces that it has been selected by the U.S. Postal Service Office of Inspector General (USPS OIG) to consolidate four of its data centers into one new state-of-the-art facility.
Distinguishing quality high power LEDs from inferior technologies most frequently centers on identifying products designed with superior thermal management to avoid loss in efficacy, decreased life hours, and color degradation.
Aggressive NREL program prods start-up companies to dramatically lower the cost of solar electricity through game-changing technologies.
NREL researchers work out a way to predict the sun's position with unmatched precision over 8,000 years.
