Does saving energy save the climate?

To stop climate change, saving energy matters less than switching to renewable energy. Indeed, says Anthony Patt, it isn't clear whether saving energy makes much of a difference at all.

New catalyst material produces abundant cheap hydrogen

QUT chemistry researchers have discovered cheaper and more efficient materials for producing hydrogen for the storage of renewable energy that could replace current water-splitting catalysts.

Putting excess carbon dioxide to good use

The chunk of metal sitting on a table in Joel Rosenthal's office at the University of Delaware looks like it should belong in a wizard's pocket. Shiny silver with shocks of pink and splashes of gold, it's called bismuth, ...

Research gives new ray of hope for solar fuel
