May 5, 2015 by Matt Conway

Lighting and Control

On the eve of Lightfair, the largest lighting show in the United States, it seems fitting to draw attention to a brewing storm that threatens the next great opportunity for deep energy conservation in commercial buildings: networked lighting controls.[read more]

LEDs: A First in Super Bowl History

February 1, 2015 by Sarah Battaglia

There’s more to the Super Bowl than face paint, air horns, and a mountain of bean dip. (Oh, and beer. We cannot forget the beer.) While the country tunes in to watch the big game Sunday night, the focus will be on the field, but when the cameras pan out, try to catch a glimpse of the lights.[read more]


Will LEDs Trigger Rebound Effects? Examining the Key Evidence

November 3, 2014 by Jesse Jenkins

Rob Day argues that the rebounds in energy demand triggered by energy efficient lighting have been overblown. This rebuttal sets the record straight, and does so by exploring the key evidence in the debate over the magnitude of rebound effects.[read more]

October 4, 2014 by Roman Kilisek

Home Lighting and Energy Use

With significant future projected power demand and over a billion people without proper access to electricity, major power generation investment will be required to liberate people from darkness and ultimately increase the untapped productivity of a swath of the population in respective developing countries.[read more]

Lighting is a 'Gateway Drug to Energy Efficiency'

May 26, 2014 by Jared Anderson

Lighting and Efficiency Adoption

Making energy efficiency appealing and sexy can be a challenge from a messaging standpoint, but it’s also an extremely effective greenhouse gas reduction tool that throws off considerable dividends in the form of reduced operating costs.[read more]

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]

The Next Stage in Energy Efficiency

June 16, 2013 by Sandy Tung

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

November 8, 2009 by Charles Barton

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]
