Last year, the Ocean Power Technologies (OPT) company has developed a tidal power generator that has now been connected to the energy grid at the Marine Corps Base Hawaii as part of the firm’s program with the US Navy to test wave energy technology, giving the US their the first-ever grid connection for a wave energy device.

The phase-out of incandescent light bulbs is part of the EU's strategy to cut greenhouse gases by 20% by 2020. Replacing the old lamps with more efficient models is expected to reduce energy consumption for lighting by 60% in the EU, equivalent to saving 30 million tons of CO2 pollution every year.

Ahead of the 2020 deadline for constituent parts of the UK to hit renewable power targets, Scotland has raised its ambitions for real-terms energy saving by switching to eco-friendly alternatives.

The two researchers tried to combine spintronics (electronics that use the spin of electrons to read/write data) with thermoelectricity, which transforms heat into electricity through the Seebeck effect. The spin-Seebeck effect (the conversion of heat to spin polarization) had been observed in action in 2008, but only on a metal rod, not on a semiconductor. They called their new heat-to-electron spin discovery “thermo-spintronics.”

The new nano-ceramics would be key components in the next generation of capacitors. Like batteries, capacitors store energy, but there the resemblance ends. Batteries are designed to collect energy over a relatively long period of time, then release it at a low, constant rate. Capacitors charge and release large amounts of power very quickly. The basic principle has been around since the 18th century, but until recently one roadblock has been how to reduce them down to an efficient size.

Light behaves differently in macro- and nano- scale environments, and this could be a starting point for those researchers who want to improve the solar cells’ efficiency. It was a starting point for some Stanford engineers, who found out that light ricocheting inside an ultra-thin polymer film solar cell behaves differently than if the film wasn’t so thin. The difference is enormous.

The two companies, in cooperation with PetersenDean Roofing and Solar Systems, announced a partnership earlier this year to pre-install solar panels at no additional cost to homebuyers at The Preserve new home community. Last Friday, September 17, Toll Brothers hosted the official ribbon-cutting ceremony to open the community to the public.

The UK environmental group Carbon Trust and Cambridge University’s Cavendish Laboratory have jointly formed a new company called Eight19 concentrating on the development of new organic photovoltaic (PV) technology that could make the installation of solar cells cheaper and easier.

One day, man-made buildings will mimic the human body in the relationship with the exterior. Penn State University researchers are about to study and implement a model that uses the sensitivity and flexibility of human cells to build “skins” that will give buildings the possibility to self-adapt to the exterior, to regulate their energy use according to changes in the environment.

We all know LED as being the flagship of green lighting, but what if those so-called “efficient” LEDs turned out to be even more energy-effective under certain conditions? The Kyoto University, in collaboration with Stanley Electric Co Ltd found a way to increase the emission intensity of silicon-based thin films by several times.

Being gifted with many active volcanoes, Central America wants to tap them for producing green energy which will cut its dependence on oil imports and also help reduce the CO2 emissions. Because the region is placed above shifting tectonic plates in the Pacific basin, it has great potential for geothermal power produced by heat stored deep in the Earth’s crust.

Recently-invented e-readers, though, do not have this issue, since they only use ambient reflections as their source of energy – mostly like regular paper. Still, current e-readers are limited to black and white, since their electrophoretic displays only know how to let light pass or block it.

Authorities have pledged to speed up construction of green buildings in response to the surge in building energy consumption that has resulted from the country's rapid urbanization. Li Bingren, chief economist at the Ministry of Housing and Urban-Rural Development (MHURD), said at a press conference Monday that authorities had made numerous efforts to save energy and reduce emissions, yet energy use efficiency remains low.

The King of Malaysia presented the trophy to the grand winner David Wendell, left, at the Earth Awards at Marlboro House in London on Thursday. David Wendell wants to revolutionize renewable energy by taking a page out of nature’s book, and improving it. His new technology captures carbon and transforms it into sugar — something that plants do naturally — more efficiently using artificial photosynthetic foam.

Doug Natelson and graduate student Dan Ward, from Rice University, have discovered how to make a light-harvesting antenna from two gold tips separated by a gap only a few nanometers wide. As light source they used a laser, whose rays, once trapped in the gold tips, get concentrated into a tiny space, increasing the light intensity in the gap by a thousand times.

The thing on the left is a snail, and it’s called abalone. Aside the fact that it’s edible, the abalone taught Angela Belcher, from MIT, how to turn carbon dioxide into rock-solid construction materials and thus sequester the gas for hundreds of thousands of years, instead of burying it underground, which is not as safe and as useful.

Chicago-based Invenergy Wind will build a farm equipped with 125 giant wind turbines on o surface of about 30,000 acre in Gratiot County, Michigan. Being considered Michigan’s largest, the $440 million project will produce 200 megawatts of energy by the end of next year, enough to supply electricity for more than 54,000 homes.

China has shown fresh interests in the development of hydropower in Nepal.
“There are opportunities for Chinese hydropower companies to participate in hydropower generation in Nepal,” said Qiu Guohong, Ambassador of China to Nepal, addressing the Nepal-China Non-Governmental Cooperation Forum meeting here in the valley today.

Verve Energy in collaboration with BP Solar are planning to build Australia’s largest ever grid-connected solar power plant. The photovoltaic power plant is expected to generate about 10MW of clean energy and according to the two companies, it will be built in Geraldton, Western Australia.

At the beginning of this month, the European division of Sanyo has officially released its new enhanced HIT solar panel. Dubbed HIT-N235SE10, the new 235 watt solar panel has an energy-efficiency of 21.1%, improving the performance in limited space installations and offering more power generation per square meter.

Summerhill Group, which is representing Ice Energy’s Ice Bear product in Canada, probably wishes the system has had more traction. Basically, the Ice Bear system uses off-peak electricity to create large blocks of ice, and then uses that ice during summer peak times to provide cooling — the idea being that it offsets the need to run air conditioners at times when electricity is most expensive.

A personal helicopter weighing just 230 lb created sizzling news when it flew on hydrogen with zero emission. With an ability to carry payloads up to 800 lbs, this pocket Hercules can fly for 90 minutes. Fitted with easy controls, this reaches a speed of 100 knots thanks to a pair of small yet powerful motors mounted on it. Two common and easily available things – Hydrogen peroxide (H2O2) and a catalyst – combined to bring about a milestone in personal aviation history with attention to the environmental issues as well! Avimech has combined these two to power engine in to an innovative machine.

The U.S. Navy’s Seal Beach facility in California is now home to a new $1.9 million solar parking lot, thanks to funding from the federal Recovery Act. Aside from creating new green construction jobs, the new solar facility will save the Navy more than $30,000 per year in electrical costs. It’s just one part of an all-around solar power makeover for the Navy, which just this summer has commissioned another $100 million worth of new solar projects.
