Friday Energy Facts: LED Bulb Efficiency Expected to Continue Improving as Cost Declines

March 21, 2014 by U.S. EIA: Today in Energy

LED Efficiency and Cost

Technology improvements for general service lighting, driven by federal efficiency standards, are leading to increased reliability and bulb life. As efficiency increases, residential electricity consumption for lighting declines over time.[read more]

Top 10 Markets for Energy Efficient Lighting

January 10, 2014 by Katherine Tweed

Energy Efficient Lighting Markets

Between the recent snow storms and the recovery from New Year’s Eve, it was actually rather easy to miss the final phase-out of the highly inefficient lighting technology we’ve known for so very long: the incandescent bulb.[read more]

Energy Efficient Lighting

Back in the 90's, the only place where you would see and LED would be on the on/off buttons of your electrical devices, and only came in red, yellow, green, and more red.[read more]

Overlooked Tax Deduction for Energy Efficiency Projects

June 28, 2011 by Don Madden

Leaving money on the table is never a good thing in business. It is however common practice for companies, landlords and others involved in Green Energy Projects. In short  the owners of buildings simply are not taking advantage of  the Energy Policy Act of 2005 Section 179D which allows for up to a $1.80/sf deduction for...[read more]

The other side of energy efficiency

September 17, 2010 by David Hone

There are two sides to the energy efficiency debate and we tend to only talk about the one which results in lower energy demand as part of an emissions reduction strategy. The other side is quite the opposite. It even has a name, the Jevons paradox. It is the proposition that technological progress that increases the efficiency with which a resource is used tends to increase (rather than decrease) the rate of consumption of that resource. In 1865, the English economist William Stanley Jevons observed that technological improvements that increased the efficiency of coal use led to the increased consumption of coal in a wide range of industries. He argued that, contrary to common intuition, technological improvements could not be relied upon to reduce fuel consumption.[read more]

The Economist: Making lighting more efficient could increase energy use

September 2, 2010 by Michael Giberson

The current issue of The Economist reports on research that concluded “making lighting more efficient could increase energy use, not decrease it.” SOLID-STATE lighting, the latest idea to brighten up the world while saving the planet, promises illumination for a fraction of the energy used by incandescent or fluorescent bulbs. A win...[read more]

How to Build a Cleantech Company Without Huge Investment Capital: A Case Study

May 19, 2010 by David Gold

While many cleantech companies require very large amounts of capital in order to get to market, there is a quiet group of cleantech companies bucking that trend.  Companies like Heartland Biocomposites (Green Building Materials), RealTech (Water Testing) and TerraLUX  (LED Lighting) all built significant and growing businesses...[read more]

Move Over OLEDs: Scientists Create Cheap, Fully Recyclable Lighting Material

February 9, 2010 by Big Gav

TreeHugger has a post on using graphene for energy efficient lighting - Move Over OLEDs: Scientists Create Cheap, Fully Recyclable Lighting Material. Swedish and American researchers have just developed a fully recyclable lighting component with what Science Daily is terms a "new super material": graphene. Graphene is both inexpensive to...[read more]

Snow and LED traffic lights

January 7, 2010 by Lynne Kiesling

The snowy weather across much of the northern hemisphere this week is being disruptive in many ways. At the Freakonomics blog, Eric Morris highlights one unanticipated and unintended disruption — snow obscuring energy-efficient LED traffic lights: The biggest weakness of LEDs is their biggest strength – they don’t radiate much heat....[read more]

David MacKay turns on a light

David MacKay is one of the brighter voices in the energy conversation. Indeed I would suspect that we would need fewer lightbulbs in any room where MacKay could be found. MacKay is now the Chief Scientist for the United Kingdom, a country which sometimes listens to scientists. [read more]

L Prize offers $10 million in light-bulb innovation competition

September 28, 2009 by Jack Mason

The L Prize competition  —sponsored by the U.S. Dept. of Energy — will substantially accelerate America’s shift from inefficient, dated lighting products to innovative, high-performance products. Just as Thomas Edison transformed illumination over a century ago, the L Prize will drive innovation and market adoption. The L Prize is...[read more]

Best Compact Fluorescent Light Bulb Guide

September 26, 2009 by Ken Levenson

While LEDs look to be the future, for the time being compact fluorescent light bulbs (CFLs) are the mass market answer to efficiency.    So as we just brought up lighting, see: I Love This Light Bulb! -  I want to share  a great guide to CFLs. The Environmental Defense Fund’s Find an Energy-Saving Light Bulb....[read more]

How many countries does it take to change a light bulb?

September 1, 2009 by Tom Raftery

Photo credit _Beat_【ツ】 Well, the EU thinks it takes 27 countries to change the light bulb. And they may well be right. Today the EU brings into force a ban on frosted and incandescant lightbulbs of 100W and over. This is the first part of a program to completely phase out incandescent light bulbs in the EU by 2012. According to the EU...[read more]

Philly’s traffic lights switch to LEDs

August 18, 2009 by ToddWallace

Philadelphia will switch the incandescent bulbs in all traffic lights to more energy efficient LEDs. Though substantially more expensive than incandescent lights - a 12-inch unit costs as much as $155, compared with $3 for an incandescent - LEDs have other advantages. They last five to 10 years, so they require much less maintenance...[read more]

Can Energy Efficient Incandescents Compete?

July 14, 2009 by Peter Troast

Can second-generation incandescents really match this? (It's a CFL). Are incandescent lightbulbs making a comeback? And if so, is it worth it?   Two years ago Congress passed a new lighting efficiency law scheduled to take effect in 2012.  When the law was written, there were no incandescent lightbulbs on the market that...[read more]
