By John Perlin Many people believe that solar energy is a twentieth century phenomenon, untried and untested. But I discovered through writing my new book Let It Shine: The 6000-Year Story of Solar Energy that houses have been designed since Neolithic times to scoop up sunlight in winter; that over the last three thousand years people have used solar concentrators…

Kenichi Hazawa, a resident of Ofunato in Japan’s Iwate Prefecture, moved into his new home this summer—a milestone in and of itself. The rebuilding job has been monumental in this coastal city, where almost one-quarter of the 15,000 homes were destroyed by the March 11, 2011, earthquake and tsunami, and nearly 8,000 people were forced…

According to Fox Business reporter Shibani Joshi, renewables are successful in Germany and not in the U.S. because Germany has “got a lot more sun than we do.” Sure, California might get sun now and then, Joshi conceded during her now-infamous flub, “but here on the East Coast, it’s just not going to work.” (She recanted the next day while…

  Former White House Chief of Staff Rahm Emanuel’s now famous comment, “Never let a serious crisis to go to waste,” could not have been more true of Hurricane Sandy, which was a harbinger of the costly destructive power of climate change.  Sandy made clear that willful ignorance of climate science and inaction is simply…

More than 180 cars are entered in Shell Eco-marathon Europe 2013, where students design and build super-low-mileage vehicles, and then prove them on a 10-mile (16.3-kilometer)…

Renewable Energy Not Growing as Fast as Necessary, Reports Say

On the road to more sustainable, clean energy, the ride has been bumpy. That’s the message to two reports this week—one from the International Energy Agency and one from the Pew Environment Group—that measured progress on transitioning from fossil fuels to clean energy. Renewable energy has stalled, both analyses point out, for a few different…

Comments Off on Purdue Solar Racing Seeks to Boost Sun Intensity

Zack Lapetina of Purdue University explains how the Purdue Solar Racing team uses high-efficiency photovoltaic panels, and then adds intensifiers to increase the amount of sunlight the cars capture for energy in Shell Eco-marathon Americas student design competition. You can also read their blog about their journey here: Lighter and Sleeker for This Year’s Race.…
