Fast Company and New Scientist have reports predicting that cheap GaN based LED lights may soon make both ncandescent and compact fluorescent light globes obsolete - Better, Cheaper LEDs Ringing Death Knell of Fluorescent Bulbs. LED lighting has long been viewed as a superior alternative to compact flourescent bulbs. Although flourescents are more electrically efficient than old-fashioned incandescent bulbs, producing them requires a complex procedure that uses a little mercury--a big environmental and health no-no. Indeed many are questioning whether CFLs are actually an environmentally-friendly choice at all.

If you use Compact Fluorescent (DC) bulbs in your home or office, you can save a lot of money as they produce very high illumination by consuming less amount of energy. They are available in 6V, 12V and 24V and can be used in solar powered systems or in any DC set up.

Compact Fluorescent lamps are becoming very popular for household use and is fast replacing the typical screw based incandescent lamps. The main reason of their popularity is that they use one third of the energy of incandescent lamps and deliver the same amount of light.

Bissell has come up with a wonderful, environmental friendly product called the Bissell 1400B Little Green Multi-Purpose Compact Earth-Friendly Deep Cleaner.

The Friedrich CP06E10 is a compact air conditioner from Friedrich and it is one of their best products in the air conditioner series. It has a cooling capacity of 6000 BTUs and the unit is really a very powerful one and is quite advanced.

Light-emitting diodes (LEDs) are better than compact fluorescent bulbs--LEDs use less energy, last longer, and contain no toxic mercury--but for general white-light illumination, they're still far too expensive for mass adoption. Now, researchers at Purdue University have taken a step toward making white LEDs with cheaper materials.

The incandescent lightbulb that wastes 90% of the electricity as heat is dying, we all know that. But a new breakthrough in solid state lighting might also kill compact fluorescent lightbulbs (CFLs) faster than some expected. Scientists at Purdue University have figured out how to manufacture LED solid-state lights on regular metal-coated silicon wafers (more details below). What this means is: much lower costs.

At the recently held EWEC 2009 wind energy conference and exhibition most exhibitors agreed that while there has been a substantial business slowdown due to problems linked to obtaining wind project financing, an upturn in demand during the second half of 2009 is beginning to play out, at least in the U.S. Other exhibitors, on the other hand, were a bit more cautious pointing out that substantial numbers of unsold turbines from framework contracts failing to secure project finance are now floating on the wind market. Most interesting from a wind technology point of view is the V112-3.0MW switch away from a compact V90-3.0MW integrated gearbox and main bearing assembly to a 3-point gearbox support. The application of a permanent magnet (PM) type generator with full converter system in the V112-3.0MW is new for Vestas but not for the wind industry. New Technology Trends In what many wind industry insiders consider a major development trend, French aerospace companies EADS Astrium & EADS Composite Aquitaine announced their formal entrance into the wind industry. The French companies offer the wind industry advanced composite materials engineering, manufacturing and related know-how as well as rotor-blade manufacturing capacity.

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."

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.

Renewable Energy World has an article on a plan to greatly expand the use of passive solar thermal energy in Europe - Action Plan for 50%: How Solar Thermal Can Supply Europe's Energy. The research efforts and infrastructure needed to supply 50% of the energy for space and water heating and cooling across Europe using solar thermal energy has been set out under the aegis of the European Solar Thermal Technology Platform (ESTTP). Published in late December 2008, more than 100 experts developed the Strategic Research Agenda (SRA), which includes a deployment roadmap showing the non-technological framework conditions that will enable this ambitious goal to be reached by 2050. A strategy for achieving a vision of widespread low-temperature solar thermal installations was first explored by ESTTP in 2006, but since then the SRA has identified key areas for rapid growth. These focus points include the development of active solar buildings, active solar renovation, solar heat for industrial processes and solar heat for district heating and cooling. Meanwhile, amongst the main research challenges is the development of compact long-term efficient heat storage technology. Once available, they would make it possible to store heat from the summer for use in winter in a cost-effective way.

If you are on a look out for an affordable, reliable and compact inverter, you are searching for the Exeltech 1100W XP.

The Midnite solar power panel is a compact panel which is used for mounting a single inverter. As a result, it saves a lot of money, time and space. It can also be used for mounting multiple inverters.

How a wall light switch timer can save energy and pay for itself in less than a year.

Inspired by the promise of vastly increased flight durations, the Russian and American militaries experimented with nuclear powered aircraft for two decades, but the concept never progressed beyond a handful of trials. Lockheed Martin's Skunk Works claims to have the solution in its grasp, unveiling plans for a compact nuclear fusion generator that could power everything from aircraft to naval vessels within ten years.
