Plant-based jet fuel could reduce emissions by 68%

Replacing petroleum-based aviation fuel with sustainable aviation fuel derived from a type of mustard plant can reduce carbon emissions by up to 68%, according...

Solar panels on half the world’s roofs could meet its entire electricity demand

Rooftop solar panels are up to 79% cheaper than they were in 2010. These plummeting costs have made rooftop solar photovoltaics even more attractive to...

Why fast charging reduces the capacity of a car battery

When lithium ions are forced rapidly through a battery, they might get stuck and turn into lithium metal, no longer able to move through...

Scientists find large solar parks could cool surrounding land for the first time

Scientists using satellite technologies have discovered for the first time that large scale solar parks have a cooling effect on the land surrounding them. As...

Scientists clear the efficiency hurdle for organic solar cells

Researchers have identified a key mechanism responsible for the lower efficiencies of organic solar cells and shown a way that this hurdle might be...

Researchers create a high performance all-solid-state battery

Engineers created a new type of battery that weaves two promising battery sub-fields into a single battery. The battery uses both a solid state electrolyte...

Everyone could build battery-free electronic devices now

Last year, computer engineers from Northwestern University and Delft University of Technology (TU Delft) introduced the world’s first battery-free Game Boy, which harvests both...

New catalyst could help generate clean energy from waste water

"We have developed a new kind of catalyst that more efficiently generates clean energy from waste water that contains urea," said the University of...

These solar cells could last 30 years and turn buildings into power plants

A new transparency-friendly solar cell design could marry high efficiencies with 30-year estimated lifetimes, researchers report. It may pave the way for windows that also...

Scientists discover new super material for batteries and other energy conversion devices

Unplanned discovery could lead to future pivotal discoveries in batteries, fuel cells, devices for converting heat to electricity and more. Scientists normally conduct their research...
