A 'high-gravity' one-pot process for producing ethanol from cellulosic biomass has been developed by scientists that gives unprecedented yields while minimizing water use and waste disposal.

Africa's urban waste: A valuable source of electricity
- by News Desk
Estimated electricity production from the total waste generated in Africa could reach 122.2 TWh in 2025, or more than 20 percent of the electricity consumed in 2010 at continental level (661.5TWh), according to a study that analyzed the potential of urban solid waste for Africa's electricity needs.

Breakthrough for iron based dyes can lead to cheaper and environmentally friendly sol
- by News Desk
Researchers have found a new way to capture energy from sunlight – by using molecules that contain iron. The hope is to develop efficient and environmentally friendly solar energy applications.

Silver: The promising electrode winner for low-cost perovskite solar cells
- by News Desk
Researchers have identified a contributing factor to short lifetime in perovskite solar cells with silver electrodes. Currently, the most common electrode material in perovskite solar cells is gold, which is extremely expensive. The low-cost alternative to gold is silver, around 65 times cheaper.

Tandem solar cells are simply better
- by News Desk
Stacking two solar cells one over the other has advantages: Because the energy is 'harvested' in two stages, and overall the sunlight can be converted to electricity more efficiently. Researchers have come up with a procedure that makes it possible to produce thin film tandem solar cells in which a thin perovskite layer is used. The processing of perovskite takes place at just 50 degrees Celsius and such a process is potentially applicable for low cost roll-to-roll production in future.

UN report takes global view of 'green energy choices'
- by News Desk
A new UNEP report offers a comprehensive comparison of the greenhouse gas mitigation potential for a number of alternative energy methods -- including wind, solar, geothermal, and hydro.

Worldwide electricity production vulnerable to climate and water resource change
- by News Desk
Climate change impacts on rivers and streams may substantially reduce electricity production capacity around the world. A new study calls for a greater focus on adaptation efforts in order to maintain future energy security.

UAE desert sand can store solar energy up to 1000°c
- by News Desk
Researchers have successfully demonstrated that desert sand from the UAE could be used in concentrated solar power (CSP) facilities to store thermal energy up to 1000°C. The research project called 'Sandstock' has been seeking to develop a sustainable and low-cost gravity-fed solar receiver and storage system, using sand particles as the heat collector, heat transfer and thermal energy storage media.

Defects could improve solar cells, researchers theorize
- by News Desk
Scientists are studying what may seem paradoxical -- certain defects in silicon solar cells may actually improve their performance. The findings run counter to conventional wisdom, according to a new paper they have published on the topic.

Global climate agreements could be counterproductive
- by News Desk
International climate agreements like the Kyoto Protocol may discourage much-needed investment in renewable energy sources, and hence be counterprodutive, according to new research.
