Daylight Saving Time does not save energy
With the switchover to daylight saving time just around the corner, you might wonder why we go to the trouble of springing forward and falling backward every year.
Light bulb with 20-year life unveiled in US on Earth Day
A prize-winning, super energy saving LED bulb from Dutch electronics giant Philips, said to last over 20 years, went on sale online and in stores Sunday to coincide with Earth Day.
MASSIVE advances in aerodynamics
Engineers are closer to understanding, and therefore manipulating, invisible aerodynamic drag forces, that cause an estimated 50 per cent of transportation fuel to be lost before we can use it.
Without plants, Earth would cook under billions of tons of additional carbon
(Phys.org) —Enhanced growth of Earth's leafy greens during the 20th century has significantly slowed the planet's transition to being red-hot, according to the first study to specify the extent to which ...
'Poisoning' corrosion brings stainless magnesium closer

Man builds most energy-efficient home he could
Saving money was never on Dennis Kaech's mind when he built his Olympia, Wash., home. But saving energy was.
Lightbulbs: The more efficient they get, the more light we use
This is a cautionary tale about a few porch lights. Once upon a time, porch lights had incandescent bulbs. Eventually, many residents subbed them out with those swirly compact fluorescent bulbs, which use a quarter of the ...
Solar energy could supply one-third of power in US West, study finds
(Phys.org) —Low-cost solar power could supply more than a third of all energy needs in the Western U.S., if the nation can hit its targets for reducing the cost of solar energy, according to a new study ...
Scientists save energy by lubricating wood
(PhysOrg.com) -- A little bit of lubrication could make a big energy saving when manufacturing sustainable biofuels and bio-chemicals from timber, according to research published in the journal Green Chemistry this month. ...
Being watched makes electricity users consume less
Magnetic power offers energy-saving alternative
The Office of Naval Research has designed a system that controls electrical flow for lighting, a highly efficient platform that may spark a new era of power savings.
The 22.8-year switch: GE's Energy Smart LED
As the common household incandescent bulb marches towards extinction (they'll be completely phased out in the U.S. by 2014), the "battle of the bulb" heats up with CFLs, LEDs, and a new long-lasting contender, ...
Engineers gain insight into turbulence formation and evolution in fluids
in the patterns that natural gas makes as it swirls through a transcontinental pipeline or in the drag that occurs as a plane soars through the sky. Reducing such turbulence on say, an airplane wing, would ...
New steering tech for heavy equipment saves fuel, ups efficiency
Researchers at Purdue University have shown how to reduce fuel consumption while improving the efficiency of hydraulic steering systems in heavy construction equipment.
