New findings have overturned a scientific dogma that stood for decades, by showing that potassium can work with graphite in a potassium-ion battery — a discovery that could pose a challenge and more sustainable, less costly alternative to the widely used lithium-ion battery.
Europe’s wind industry has sharply criticised the Spanish government over last week’s 700MW renewables auction – which included 500MW of wind – as being too small to satisfy demand, and warned it leaves the country at risk of missing its 2020 EU targets.
Wind surpassed nuclear to become the third largest generation source in the main Texas electricity market in 2015, the largest and among the fastest growing in the US.
An international research team reports that the rapid increase in global carbon dioxide emissions from fossil fuels has slowed in the past two years, underlining the need for action to permanently lower emissions.
Vanderbilt engineers have discovered that adding quantum dots made from fool’s gold to the electrodes of standard lithium batteries can substantially boost their performance.
adminAn ultra-high-resolution technique used for the first time to study polymer fibers that trap uranium in seawater may cause researchers to rethink the best methods to harvest this potential fuel for nuclear reactors.
adminIn very cold climate zones, the wind can blow with tremendous force. But wind turbines have rarely been built in these regions up to now. The risk of ice formation on the rotor blades is just too high. But now, an energy-efficient heating system frees these turbines from the ice in a matter of seconds. It is only switched on when water freezes.
