Switzerland has a long history of trying to be as self-sufficient and energy independent as possible. Although its energy supply system has served it well in the past, the country is now looking to turn away from its reliance on nuclear power and seeks to compensate for the energy lost from hydropower as a result of climate change.
The longest and most difficult leg of the Round the World Solar Flight attempted since last March by Swiss explorers Bertrand Piccard and André Borschberg ended successfully in Hawaii. At the controls of Solar Impulse 2, pilot André Borschberg landed safely in Hawaii after flying 117 hours and 52 minutes over the Pacific Ocean from Japan powered only by the sun.
Wind turbines could be installed under some of the biggest bridges on the road network to produce electricity. So it is confirmed by calculations carried out by a European researchers team, that have taken a viaduct in the Canary Islands as a reference. This concept could be applied in heavily built-up territories or natural areas with new constructions limitations.
A materials science and engineering team has developed a new energy cell that can store large-scale solar energy even when it's dark.
Building on a unique idea, scientists have developed a cost-effective new method for converting and storing solar energy into hydrogen.
A photoprotective mechanism in cyanobacteria is triggered by an unprecedented, large-scale movement from one location to another of the carotenoid pigment within the Orange Carotenoid Protein, researchers have discovered.
Researchers are making better heat exchangers for industrial use using the same plastic as in garbage bags.
Researchers achieved 15% energy conversion efficiency in perovskite solar cells for the first time certified at an international public test center.
A new technique for 'scheduling' energy in electric grids has been developed. It moves away from centralized management by tapping into the distributed computing power of energy devices. The approach advances the smart grid concept by coordinating the energy being produced and stored by both conventional and renewable sources.
Scientists have developed a new power converter chip that can harvest more than 80 percent of the energy trickling into it, even at the extremely low power levels characteristic of tiny solar cells. Previous experimental ultralow-power converters had efficiencies of only 40 or 50 percent.
In 2013, Russia implemented an incentive system for renewable energy sources that is based on the wholesale electricity capacity mechanism. It is intended to increase the share of renewable energy in the country's energy production. New researchers demonstrates that the incentive system can make renewable energy investments in wind, solar and small-scale hydro power profitable for investors. However, in order to be profitable the investments must be within the scope of the full Russian support scheme.
Chemists have developed a major improvement to capture and retain energy from sunlight, where the stored energy can last dramatically longer than current solar technology allows -- up to several weeks, instead of the microseconds found in today's rooftop solar panels.
Researchers have developed a material suited for photovoltaics. For the first time, a functioning organic solar cell consisting of a single component has been produced on the basis of metal-organic framework compounds (MOFs). The material is highly elastic and might also be used for the flexible coating of clothes and deformable components.
Researchers have achieved a 15% energy conversion efficiency in perovskite solar cells for the first time in the world, as officially recognized by an international public test center.
Efficiently turning sunlight into storable fuels requires catalysts that convert a maximum amount of solar energy into fuel. A lack of standardized analytic conditions and methods has made objectively comparing catalysts challenging. Scientists standardized measurement techniques to allow a quantitative, objective evaluation of such catalysts.
By smoothing the surface of hematite, a team of researchers achieved the first 'unassisted' water splitting using the abundant rust-like mineral and silicon to capture and store solar energy within hydrogen gas.
A new methane bioreactor boosts environmentally friendly energy to the markets. The reactor stores renewable energy and produces synthetic biomethane with good efficiency. The new technology can help in achieving a carbon-neutral society, developers report.
It's technically possible for each state to replace fossil fuel energy with entirely clean, renewable energy, experts say. A new report is the first to outline how each of the 50 states can achieve such a transition by 2050. The 50 individual state plans call for aggressive changes to both infrastructure and the ways we currently consume energy, but indicate that the conversion is technically and economically possible through the wide-scale implementation of existing technologies.
Perovskite solar cells are promising low-cost and highly-efficient next-generation solar cells. Now a research team has successfully developed perovskite solar cells with good reproducibility and stability as well as exhibiting ideal semiconducting properties.
Researchers have learned how to eliminate pesky pinholes in perovskite solar cells. The pinholes in the top layer of the solar cell, known as the hole transport layer, were identified as a key cause for the quick degradation of perovskite solar cells. Researchers around the world are investigating the potential of perovskite, a humanmade organic-inorganic hybrid material, as an alternative to silicon-based solar cells.
