today's G word

Light-emitting Diode (LED) is a semi-conductor light source valuable as a long-lasting illumination technology.  When a diode is forward biased (switched on), electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the color of the light, corresponding to the energy of the photon, is determined by the energy gap of the semiconductor.

These energy-efficient lights consume 80 percent less energy than conventional, incandescent bulbs. Common in digital clocks, remote controls, watches and appliances, they are now being produced in bulb form as a home lighting alternative.

Smart Grid Gets Smarter by Using Advanced Lithium Ion Battery Technology


Advanced lithium-ion battery maker EnerDel is ready to enter the utility-scale energy storage market. Its battery technology will support a major new smart grid program announced yesterday by the US Department of Energy. 

EnerDel will build batteries for five one-megawatt power systems used by Portland General Electric (PGE). The goal: to help manage peak demand and smooth the variations in power from renewable sources like wind and solar.

Business Going Green: Exclusive GTTV Series

The need for sustainable business practices is rapidly approaching a tipping point in companies both large and small. They’re learning that sustainability is much more than just good citizenship, it’s also good for the bottom-line.

But once a company decides to “go green,” the question becomes, “How do we do it?"


GreenTech TV sat down with eBay to find out what’s driving their sustainability success.  (The eBay Green Team started out as an employee group — just 40 colleagues getting together to talk about how to make eBay a greener company. Today, more than 2,400 employees are members, representing 23 countries around the world.) http://www.ebaygreenteam.com/green-at-ebay

Recently, GreenTech TV Editor, Karen Nelson had the privilege to interview Libby Reder, eBay’s Head of Environmental Initiatives, and co-founder of the eBay Green Team to find out what is driving eBay’s green successes.

Horizon Fuel Cell Technologies to release a portable at home hydrogen fuel cell storage and charging station that has great potential.  From the near term impacts of charging your electronics, to the new doors it may open with at home fuel cell charging, their technology is definitely worth reseaching.

 Cavitation Technologies’ (CTI) innovative HydorFuel presents promising preliminary results on the hydro-fuel technology.  The results proved this innovative fuel provided a more efficient burn and cleaner emissions while lowering operating costs, specifically for marine diesels and turbine power generators.

In December, scientists at Sandia National Laboratories announced their development of tiny glitter-sized photovoltaic cells.
