More than 100 experts from around the world contributed to present findings and recommendations on current production and use of bioenergy, as well as growth potential, considering such aspects as land use, feedstocks, technologies, impacts and policies.
New research indicates that oranges could have potential far beyond the breakfast table. The chemicals in orange peel could be used as new building blocks in products ranging from plastics to paracetamol - helping to break our reliance on crude oil.
The mixed oxide catalyst could solve the longstanding problem of inhibition, in which nitrogen oxides, carbon monoxide and hydrocarbons effectively clog the catalyst designed to cleanse a vehicle's exhaust stream.
Solar cells capture up to 40 percent more energy when they can track the sun across the sky, but conventional, motorized trackers are too heavy and bulky for pitched rooftops and vehicle surfaces. Now, by borrowing from kirigami, the ancient Japanese art of paper cutting, researchers have developed solar cells that can have it both ways.
In the future, a wireless charging system will allow electric cars not only to charge their batteries, but also to feed energy back into the power grid, helping to stabilize it. The cost-effective charging system achieves high levels of efficiency across the whole power range, from 400 watts to 3.6 kilowatts, while the car and the charging coil can be up to 20 centimeters apart.
In the world of computer gaming, bragging rights are accorded to those who can boast of blazing-fast graphics cards, the most powerful processors, the highest-resolution monitors, and the coolest decorative lighting. They are not bestowed upon those crowing about the energy efficiency of their system. If they were, gaming computers worldwide might well be consuming billions of dollars less in electricity use annually, with no loss in performance, according to new research.
Intermittency is one of the problems affecting renewable energies, including marine energy: sometimes there's a lot; other times it's in short supply. So to properly manage sea energy and incorporate it into the mains, it is helpful to know when the waves are expected to be bringing sufficient power.
