Non-toxic alternative for next-generation solar cells
18 Jul 2017 at 8:37am
Researchers have demonstrated how a non-toxic alternative to lead could form the basis of next-generation solar cells.
Rooftop concentrating photovoltaics win big over silicon in outdoor testing
17 Jul 2017 at 9:57am
A concentrating photovoltaic system with embedded microtracking can produce over 50 percent more energy per day than standard silicon solar cells in a head-to-head competition, according to a team of engineers who field tested a prototype unit over two sunny days last fall.
Nanomaterial helps store solar energy: Efficiently and inexpensively
17 Jul 2017 at 8:57am
Since solar and wind energy is not always available, it will only contribute significantly to meeting energy demands once a reliable storage method has been developed. Now a new catalyst material for electrolysers is proving to be reliable, shows new field trials.
Unbalanced wind farm planning exacerbates fluctuations
17 Jul 2017 at 8:53am
If European countries cooperated better in the field of wind energy, wind power output would fluctuate less. This is the conclusion reached by a group of energy and climate researchers who, for the first time, have combined a long-term analysis of predominant weather patterns with Europe-wide wind electricity generation.
Scientists design solar cell that captures nearly all energy of solar spectrum
11 Jul 2017 at 7:05pm
Scientists have designed and constructed a prototype for a new solar cell that integrates multiple cells stacked into a single device capable of capturing nearly all of the energy in the solar spectrum.
Surveying sea floor animals for offshore renewable energy
7 Jul 2017 at 6:58am
Chunks of sediment from the ocean floor are being used by scientists to analyze animal life and determine environmental impact from offshore energy facilities.
'Smart' transformers could make reliable smart grid a reality
5 Jul 2017 at 8:31am
Smart solid-state transformers could be used to make a stable, reliable 'smart grid' -- allowing the power distribution system to route renewable energy from homes and businesses into the power grid -- a new study using complex computational models finds.
Self-powered system makes smart windows smarter
30 Jun 2017 at 8:56am
Researchers developed a new type of smart window: a self-powered version that promises to be inexpensive and easy to apply to existing windows, with potential to save heating and cooling costs. The window powers itself with a transparent solar cell that harvests near-ultraviolet light.
Biofuel from waste: Zeolite catalysts pave the road to decentralized chemical...
28 Jun 2017 at 2:21pm
Fuel from waste? It is possible. But hitherto, converting organic waste to fuel has not been economically viable. Excessively high temperatures and too much energy are required. Using a novel catalyst concept, researchers have now managed to significantly reduce the temperature and energy requirements of a key step in the chemical process. The trick: the reaction takes place in very confined spaces inside zeolite crystals.
Air pollution casts shadow over solar energy production
26 Jun 2017 at 10:57am
Global solar energy production is taking a major hit due to air pollution and dust. The first study of its kind shows airborne particles and their accumulation on solar cells is cutting energy output by more than 25 percent in certain parts of the world. The regions hardest hit are also those investing the most in solar energy installations -- China, India and the Arabian Peninsula.
New catalyst paves way for carbon neutral fuel
21 Jun 2017 at 7:31am
Scientists have paved the way for carbon neutral fuel with the development of a new efficient catalyst that converts carbon dioxide (CO2) from the air into synthetic natural gas in a 'clean' process using solar energy.
Solar heating could cover over 80 percent of domestic heating requirements in...
20 Jun 2017 at 8:41am
By using suitable systems, more than 80 percent of heating energy for Finnish households could be produced using solar energy with competitive prices. This result is also valid for Sweden, Norway, Alaska, northern Canada and other locations at the same latitudes.
Future trucks fueled by hydrogen created with solar power: Exhaust? Pure wate...
20 Jun 2017 at 6:45am
Heavy-duty trucks will soon be driving around in Trondheim, Norway, fueled by hydrogen created with solar power, and emitting only pure water vapor as ?exhaust?. Not only will hydrogen technology revolutionize road transport, it will also enable ships and trains to run emission-free.
Fighting global warming and climate change requires a broad energy portfolio
19 Jun 2017 at 12:22pm
Can the continental United States make a rapid, reliable and low-cost transition to an energy system that relies almost exclusively on wind, solar and hydroelectric power? While there is growing excitement for this vision, a new study describes a more complicated reality. Researchers argue that achieving net-zero carbon emissions requires the incorporation of a much broader suite of energy sources and approaches.
Could renewable 'power-by-wire' help fix China?s air pollution problems?
16 Jun 2017 at 9:17am
Bringing renewable power ?by wire? from western China to its power-hungry Eastern cities could have benefits for both local air quality and global climate change, new research has found.
