As the installation of photovoltaic solar cells continues to accelerate, scientists are looking for inexpensive materials beyond the traditional silicon that can efficiently convert sunlight into electricity. Theoretically, iron pyrite — a cheap compound that makes a common mineral known as fool’s gold — could do the job, but when it works at all, the conversion efficiency remains frustratingly low. …

  It’s no secret electric and hybrid cars are popular with consumers. But what if small business owners could turn their current vehicle — even a commercial van or truck — into a hybrid? Researchers at Fairleigh Dickinson University in New Jersey have developed a new kind of plug-in hybrid system for commercial vehicles. “This system is the first of …

What if we could take all that carbon dioxide that we have too much of and turn it into a clean energy source? Sound far-fetched? Well, it isn’t really. After all, plants do it every day. That is much of the rationale behind biofuels. Let the plants store the solar energy as sugars, starches, etc., which we then convert into …

The Alcatraz Microgrid: Life on ‘The Rock’ Not Easy, Even for a Microgrid The Alcatraz microgrid stands as a model for installing modern energy technology under difficult terms.
