Cheaper, longer-lasting perovskite solar cells could be on the way

Perovskite solar cells are one of the most exciting green energy technologies to emerge in recent years, combining low cost with high energy conversion rates. Now, researchers at the Swiss Federal Institute of Technology in Lausanne (EPFL) have found a way to cut their cost even further by developing a charge-carrying material that is much cheaper, highly efficient, and could even help address the technology's current major weakness by significantly lengthening the lifespan of the panels.Read More

GE turns out the lights on CFLs

Compact fluorescent lamps (CFLs) that could fit into standard light sockets only hit the market in the 1980s, but the signs are their days may be numbered. GE has announced it will cease production of CFLs this year and instead switch its focus to producing LEDs.Read More

Study looks at long-term impact of farming

Human use of land for crops and herds has completely altered the world's landscapes. A new field of research called experimental socio-ecology looks to the past to predict the consequences of this type of human activity in the future. Researchers at Arizona State University have spent the last 10 years studying the effects that small-scale farmers have had on land in the Mediterranean, and now they have released a report with the findings of the project.Read More

Statistically, humanity is almost certainly responsible for global warming

The world is getting warmer, with 13 out of the 15 warmest years on record occurring in the current century. But just how sure are we that humanity's burning of oil and coal is the key factor in the temperature increase? A new project, led by researchers at the Potsdam Institute for Climate Impact Research, has answered that very question, working to estimate the likelihood of those temperature trends occurring naturally.Read More

Plant openings signal "birth of large-scale solar in Australia"

According to the Energy Supply Association of Australia, Australia boasts the highest rate of household solar panel installation in the world. But despite much of the continent being seemingly perfect for large scale solar, it has been slow in coming to the sun-drenched country. That could be set to change with the official opening of two plants that AGL Energy managing director and CEO Andy Vesey says "signals the birth of large-scale solar in Australia".

Giant clams could inspire better color displays and solar cells

Researchers from the University of California at Santa Barbara have discovered that giant clams may hold the key to improving solar cells and color displays. The new findings indicate that at least two species of giant clams produce a white coloration by combining red, green and blue light, in a manner similar to what occurs in television and smartphone displays.Read More

Breaking down humanity's contribution to climate change

Over the past 100 years, global temperatures have risen by an average amount of 0.8° C (1.4° F), which according to the Intergovernmental Panel on Climate Change (IPCC), is due largely to humanity's release of pollutants into the atmosphere. Now an international team of researchers has analyzed almost 40 years worth of data in order to quantify exactly what fraction of the change can be attributed to mankind based on events and trends in different regions.Read More
