Solar panels: Nanotechnology gives green energy a green color
15 Aug 2017 at 9:05am
Solar panels have tremendous potential to provide affordable renewable energy, but many people see traditional black and blue panels as eyesores. Architects, homeowners and city planners may be more open to the technology if they could install colorful, efficient solar panels, and a new study brings us one step closer. Researchers have developed a method for imprinting existing solar panels with silicon nanopatterns that scatter green light back toward an observer.
Night vision for bird- and bat-friendly offshore wind power
11 Aug 2017 at 7:20am
ThermalTracker software analyzes video with night vision, the same technology that helps soldiers see in the dark, to help birds and bats near offshore wind turbines.
Turning homes into power stations could cut household fuel bills by more than...
9 Aug 2017 at 4:33am
Energy bills could be cut by more than 60 percent -- saving the average household over £600 a year -- if homes were designed to generate, store and release their own solar energy, a report has revealed. The concept has already been proven and is operating successfully on a building in the UK.
Prairie-chicken nests appear unaffected by wind energy facility
9 Aug 2017 at 4:33am
Wind energy development in the Great Plains is increasing, spurring concern about its potential effects on grassland birds, the most rapidly declining avian group in North America. However, a new study suggests that for one grassland bird species of concern -- the greater prairie-chicken -- wind energy infrastructure has little to no effect on nesting. Instead, roads and livestock grazing remain the most significant threats to its successful reproduction.
Power-to-liquid: 200 liters of fuel from solar power and the air's carbon dio...
8 Aug 2017 at 3:24pm
Production of fuels from regenerative electric power is a component of the energy turnaround. The first 200 l of synthetic fuel have now been produced from solar energy and the air's carbon dioxide under the SOLETAIR project. The mobile chemical pilot plant that can be used decentrally produces gasoline, diesel, and kerosene from regenerative hydrogen and carbon dioxide.
Annual wind report confirms tech advancements, improved performance, low wind...
8 Aug 2017 at 11:55am
Wind energy pricing for land-based, utility-scale projects remains attractive to utility and commercial purchasers, according to an annual report released by the US Department of Energy. Prices offered by newly built wind projects in the United States are averaging around 2¢/kWh, driven lower by technology advancements and cost reductions.
Distributed wind power keeps spinning, growing
8 Aug 2017 at 11:55am
America's use of distributed wind -- which is wind power generated near where it will be used -- continues to grow, according to the 2016 Distributed Wind Market Report.

New carbon dioxide experiments may lead to artificial, renewable fuels, outlines new research. In chemical reactions performed in the lab, a research team has identified a new additive that helps selectively convert carbon dioxide into fuels containing multiple carbon atoms -? a step toward ultimately making renewable liquid fuels that are not derived from coal or oil.
Vertical axis wind turbines can offer cheaper electricity for urban and subur...
3 Aug 2017 at 7:31am
Small vertical axis wind turbines (VAWTs) possess the ability to effectively operate in the presence of high turbulent flow, which makes them ideal energy harvesting devices in urban and suburban environments. In a new article, researchers present results indicating that an optimally designed VAWT system can financially compete with fossil-fuel based power plants in urban and suburban areas, and even spearhead the development of a net-zero energy building or city.
Solar glasses generate solar power
2 Aug 2017 at 7:28am
Organic solar cells are flexible, transparent, and light-weight -- and can be manufactured in arbitrary shapes or colors. Thus, they are suitable for a variety of applications that cannot be realized with conventional silicon solar cells. Researchers now present sunglasses with colored, semitransparent solar cells applied onto lenses that supply a microprocessor and two displays with electric power.
Oil fields: Alternative to wasteful methane flaring
1 Aug 2017 at 6:02am
Researchers say they have a solution to the oil field flares wasting 3.5 percent of the world's natural gas: an inexpensive reactor that can convert methane to electricity.
Robust catalyst to split water into hydrogen, oxygen produced
26 Jul 2017 at 10:17am
A single, robust catalyst that splits water into hydrogen and oxygen has been developed with Earth-abundant materials that approach the efficiency of more expensive platinum, according to scientists.
Solar scientists rough up silicon panels to boost light capture
26 Jul 2017 at 7:29am
Scientists enhance conversion efficiency of crystalline Si solar cells by effectively preventing reflection loss, passivating a submicron silicon structure, and adding a rough nanoscale surface texture using simple and inexpensive processes.
New membranes help reduce carbon dioxide emission
26 Jul 2017 at 6:20am
Scientists are developing membranes for an efficient separation of gasses, to use for the production of oxygen or hydrogen, for example.
Trees can make or break city weather
26 Jul 2017 at 6:15am
Even a single urban tree can help moderate wind speeds and keep pedestrians comfortable as they walk down the street, according to a new study that also found losing a single tree can increase wind pressure on nearby buildings and drive up heating costs.
