Technology Review has an update on cheap, energy efficient OLED lighting - Ultra-Efficient Organic LEDs.
An organic light-emitting diode (OLED) developed in Germany has the potential to produce the same quality of white light as incandescent bulbs but with power efficiencies considerably better than even fluorescent lighting.
The prototype OLED could emerge as an ultra-efficient light source for displays and general lighting, says Sebastian Reineke, who led the research at the Institute for Applied Photophysics, in Dresden, Germany. The long-term goal is to fabricate the device using conventional low-cost roll-to-roll printing.
In recent years, many countries have begun looking to switch from incandescent lighting to compact fluorescent bulbs because the latter are so much more energy efficient. There has also been a lot of interest in using light-emitting diodes (LEDs) for displays and general lighting, again because of the potential energy savings they offer.
But with both fluorescent and LED lighting, the quality of white light produced has always left something to be desired. Fluorescent lighting can make people appear unhealthy because less red light is emitted, while most white LEDs on the market today have a bluish quality, making them appear cold.
During Earth Week, visitors to the U.S. Department of Energy website -- energy.gov -- will be immediately directed to a special web feature giving them key energy saving tips and user-friendly information about the critical emerging technologies and initiatives underway to move the nation toward a clean energy economy.
The webpage is intended to help people enjoy a more green lifestyle by making simple adjustments. It details steps consumers can take to make informed energy decisions, save money on monthly bills, become more energy efficient, and protect the environment. These money saving tips include monitoring energy usage in homes, purchasing fuel efficient hybrid and plug-in hybrid cars, insulating homes, using Lighting Emitting Diodes (LED) and Compact Florescent Light (CFL) bulbs and using power strips to fully shut off multiple appliances and electronics at once when not in use.
"Earth Week is a fitting time for all of us to reevaluate our personal energy habits," Secretary Chu said. "By taking simple steps to reduce our energy use, all Americans can strike a blow for energy independence, while saving money on energy bills and moving America toward a clean energy future."

The world is finally doing something about climate change. People are changing their light bulbs and buying hybrid vehicles. Renewable energy is gaining ground. But is this enough? Policy-makers insist that environmental responsibility not come at the expense of economic growth. Massive populations in China and India are playing catch-up with America's consuming and polluting ways. And on a planet biologists believe can only support a few billion humans over the long haul, our population is near seven billion and continuing to rise. Will our efforts to save the planet be nullified by our worship of growth?
