General Electric has created new halogen compact fluorescent light bulbs, GE Reveal and GE Energy Smart Soft, that unlike typical fluorescents (CFLs), contain less mercury (only 1 milligram) and don’t take time to warm up, being more efficient.

The European Hydrogen Association (EHA) and the European Regions and Municipalities Partnership for hydrogen and fuel cells (HyRaMP) have called for accelerated support from the EU, national and local governments to ensure a sustainable build-up of hydrogen infrastructure in Europe. Both organizations stress the need to integrate hydrogen infrastructure development into the EU’s current energy and transport infrastructure plans.

Making a cellphone battery last ten times longer is a first target for a large research project that IBM, Infineon and a number of European universities unveiled on Wednesday. The new research project, called Steeper, also aims to decrease the energy needs of other electronic devices like TV sets or supercomputers by 10 times when active, and to virtually eliminate power consumption when they are in standby mode.

A new clean tech company called Totempower Energy Systems Ltd. has come up with an easy way to put wind power within the grasp of everyday homeowners. The company is developing new micro-wind turbines that are designed for close quarters and non-disruptive installation, but the real key to getting more micro-wind turbines into consumers’ hands is the company’s “ease of ownership” plan which provides a soup-to-nuts service including site selection and connecting the turbine to the home electrical system.

Solar panels are usually mounted in series, to sum up their voltages, and the resulting power is sent to a large inverter, which transforms the DC voltage into AC. One big issue with this scheme is that if shade falls on one panel, or it gets dirty, the inverter lowers the current of all the other panels, and causing power losses through inefficiency.

MIT researchers are hopeful of capturing and releasing solar energy with the help of thermo-chemical technology. Scientists were already working on this technology in seventies but this project was aborted due to its expensiveness and termed as too impractical to achieve. But MIT researchers are now gearing up to take this thermo-chemical technology that is supposed to convert solar energy into electrical energy.

A New Zealand firm is hoping to beat rivals to Britain's lucrative boiler replacement market with its energy-efficient product and says an IPO (initial public offering) in Europe could be on the cards as it ramps up production. Whisper Tech, controlled by New Zealand state power group Meridian, expects to be profitable within a year and is examining its funding options over the next 12-18 months as it moves into mass production.

The Coca-Cola company has been introducing more electric vehicles and other low-emissions trucks into its massive fleet, and now researchers at the Hong Kong Polytechnic University are developing yet another alternative energy option. The team has been working on a solar powered air conditioning system that would significantly reduce or eliminate beverage delivery truck emissions related to cooling.

The Abu Dhabi Distribution Company (ADDC), which supplies electricity to the city and surrounding areas, will have installed digital electricity meters in all buildings by the end of this year, its deputy managing director Abdulrahman al Dhaheri said yesterday. The new meters not only calculate power usage, but also allow consumers to sell their own solar-generated electricity back to the grid.

The United States is on the verge of a solar boom that could provide 4.3 percent of the nation's electricity by 2020, according to a new report from Bloomberg New Energy Finance. There's just a 12-figure catch: Investors need to put $100 billion into the solar industry to keep the generation of solar electricity growing by 42 percent a year for the next decade to expand capacity from the current 1.4 gigawatts to 44 gigawatts.

Only to the visually-impaired it may look like fuel cells and electric cars don’t enjoy success nowadays. Daimler AG has just started a pilot program of leasing Mercedes-Benz hydrogen fuel cell cars to 5 to 15 users in the US, to see how their car acts in real life conditions and how people receive them. To me this looks like a postpone of the real thing, just like GM did to EV1.

This is the third day in a row that we are presenting the most efficient lighting systems invented recently. Now, it’s time for another invention from GE, who made a 1,500-lumen LED light bulb and cooled it through a technology used in aviation.

While Compact Fluorescent Bulbs have barely been seen in various parts of the world and incandescent lighting still rules in others, two Japanese companies already want to change them for LEDs – straight tube LED lamps, which, they say, are much more economical.

Weighing under 454 kilos (1,000 lbs), the Honda Air is run by a compressed air motor, with the energy held inside compressed air in pressurized tanks. It’s “programmed” to have an autonomy of around 100 miles and has a pneumatic regulator system.

Siemens has landed an order to supply 80 wind turbines for the Dan Tysk wind farm off Germany's North Sea coast. With a total capacity of 288 MW, the farm will begin supplying clean electricity to 500,000 German households in 2014. Dan Tysk Offshore Wind GmbH is owned by Vattenfall Europe with a 51 percent stake and Stadtwerke Munchen with a 49 percent stake.

A few days ago, the Israel-based energy company ZenithSolar has officially unveiled its 3rd generation Solar Z20. Being installed in Kibbutz Yavne in central Israel, the solar energy generator is a combined heat and power system, able to deliver 72% efficiency.

The first factory to manufacture the Nissan Leaf, in Oppama, Japan, started producing functional units on October 22. The first shipments will be made to Japan and the US this November and to Europe starting December. The Nissan Leaf uses lithium-ion batteries made by Automotive Energy Supply Corp, the joint venture between NEC and Nissan.

Floating wind turbines are a little more complicated and require higher initial costs. But a new study, Project Deepwater, by the Energy Technologies Institute (ETI) in the UK has found that due to their greater ability to access stronger and more consistent winds deeper out at sea, they are more economically efficient in the long term.

It is not that unusual for offshore oil to develop offshore wind technology. The two share some of the same technical and engineering issues. Stat-Oil in Norway is also investing in offshore wind development, because many of the engineering solutions found to develop offshore oil, are also applicable to the development of offshore wind, like building platforms in deep sea.

According to Mazda Motor Corp, the new Mazda2 subcompact will have a fuel economy of 30 km/litre (70 mpg) and as the company said, it will become the world’s most fuel-efficient vehicle. Mazda2 is scheduled to be launched in Japan in the first half of 2011, being the first car fitted with SKYACTIV, a technology produced only by Mazda based on next-generation gasoline and diesel engines.

We’ve been talking a while ago about Michael Strano and his thin carbon nanotubes that can transform fuel poured onto them into electricity. A chemical reaction is set up by heating the nanotubes, triggering the transformation at a speed of 10 meters per second.

While disposal of sharps (used needles and syringes) at hospitals and other large healthcare facilities is highly regulated, medical waste disposal by the ten million people who self-inject at home for diabetes and other conditions is largely unregulated. The health risks and resulting economic costs of improper sharps disposal are immense, from needles and syringes washing up on beaches and possibly creating needlesticks, to needlestick injuries that can expose sanitation and other workers to infection risk.

The project is following up on a pre-feasibility study conducted by the Clinton Climate Initiative. Fluor’s task is to develop a conceptual master plan to be unveiled at the South African Solar Park Investors Conference (Oct. 28 and 29), which will be held in the Northern Cape Province.

Results from EECA's energy audit programme show that on average, companies can shave 20% off their energy use and costs - 10% at little or no cost and a further 10% with a simple payback of less than five years. Typically, for every dollar invested in an energy audit, $7.50 of energy savings are identified.

Leave it to larger-than-life Texas to lead the U.S. into a new energy future. While the state is most closely associated with oil, it has also been an early pioneer of wind power, and is beginning to embrace solar energy along with armloads of new green jobs. Now the San Antonio Water System has set the national bar high in the sewage-to-biogas field, by becoming the first water district to hook a biogas facility up to a commercial gas pipeline.

With the second largest tidal range in the world, about 50 feet, the Severn estuary has been eyed for years as a potential energy source, particularly as the appetite for sustainable energy sources has been growing over the last few years. The U.K. has pledged to have 40 percent of its electricity generated from renewable sources by 2020 to meet European Union requirements.
