Solar power day and night: KIT controls fluctuation of renewable energies by using modern storage systems
Energy storage systems are one of the key technologies for the energy turnaround. With their help, the fluctuating supply of electricity based on photovoltaics and wind power can be stored until the time ...
New method to encourage virtual power plants for efficient renewable energy production
Researchers from the University of Southampton have devised a novel method for forming virtual power plants to provide renewable energy production in the UK.
Are consumers aware that they are drawn to the center when choosing products?
Consumers are more likely to select products located in the horizontal center of a display and may not make the best choices as a result, according to a new study in the Journal of Consumer Research.
Aqueous iron interacts as strong as solid iron
German scientists have applied a new method -- "inverse Partial Fluorescence Yield" (iPFY) on micro-jet -- which will enable them to probe the electronic structure of liquids free of sample damages. The experiments ...

With $1.5 million from the Department of Energy, University of Arizona researchers are continuing to improve groundbreaking technology to produce solar electricity at a price competitive with non-renewable ...
Computing advances vital to sustainability efforts; new report recommends problem-focused, iterative approach to researc
Innovation in computing will be essential to finding real-world solutions to sustainability challenges in such areas as electricity production and delivery, global food production, and climate change. The immense scale, numerous ...
New study forecasts sharp increase in world oil production capacity, and risk of price collapse
(Phys.org) -- Oil production capacity is surging in the United States and several other countries at such a fast pace that global oil output capacity is likely to grow by nearly 20 percent by 2020, which could prompt a plunge ...
Low-carbon farming takes root in Brazil's Amazon
Manoel Jose Leite, a small-scale organic farmer, is set to pioneer low-carbon agriculture in Brazil's Amazon rainforest, which for decades has been destroyed by expanding agribusiness.
High-speed method to aid search for solar energy storage catalysts
Eons ago, nature solved the problem of converting solar energy to fuels by inventing the process of photosynthesis.
Annual Arctic sea ice less reflective than old ice
In the Arctic Ocean, the blanket of permanent sea ice is being progressively replaced by a transient winter cover. In recent years the extent of the northern ocean's ice cover has declined. The summer melt season is starting ...
When the soil holds not enough phosphorus: Scientists describe new transporter in cells of plant roots
Plants cannot survive without phosphorus. It forms the backbone of many crucial molecules (such as DNA) and is a key player in energy transfer reactions. Low availability of phosphorus is a major environmental ...
A comprehensive antidote to a challenging global oil picture
In a changing, often unpredictable world, says Karen Timmerman, only a balanced and comprehensive plan can improve United States energy policy.
Folding light: Wrinkles and twists boost power from solar panels
Taking their cue from the humble leaf, researchers have used microscopic folds on the surface of photovoltaic material to significantly increase the power output of flexible, low-cost solar cells.
How the ecological risks of extended bioenergy production can be reduced
For years experts have discussed the ecological impact of the extended cultivation of energy crops. Scientists have now developed a computer model that allows assessing the impacts and comparing the effectiveness ...
