How’d Earth Day treat you this year?

Well, April 22 has come and gone. How was Earth Day for you? Take our poll below!

E.U. plows ahead with coal

Even as it makes plans to cut greenhouse-gas emissions, the European Union is gearing up to put some 50 coal plants on line in the next five years. Europeans’ distaste for nuclear energy and the relative cheap cost of coal — even when carbon permits are factored in — have made the black rock attractive […]

Umbra on planning a lawn

Umbra, I’m not a big fan of lawns, but I do want some nice grass cover on at least part of my yard, especially the steep slope on the side of the house. I was looking into native grass species, but from what I’ve found so far the warm weather grasses native to the Northeast […]

Browse the web like an eco-chic geek

The eco-revolution will not be televised. This time, it’s on the web in the form of a sleek new web browser at Flock.com. If you want to keep tabs on the latest green scene while staying caught up on whatever your friends are doing, then the Flock Eco browser is all you need. Based on […]

Study: transgenic soy brings lower yields than conventional

Genetically modified organisms (GMOs) came to dominate U.S. grain agriculture over the last 12 with very little real public debate. Sure, people like me have complained loudly, and groups like Center for Food Safety have mounted forceful lobbying and public education efforts. But U.S. policymakers have ignored these criticisms and chosen to wave these epoch-making […]

Everyday choices depend more on culture, infrastructure, economics, and values

I see Maywa beat me to the "I really like Michael Pollan, but ... " post. I too was disappointed with Pollan's answer to the question of "Why Bother?" As in, why bother taking personal steps to reduce one's contribution to climate change? I will say this, though: the article did sharpen my thinking about why I think we should bother.

One of the things I've always admired about Pollan's writing is his knack for delivering sly polemic that hangs equally on scientific arguments and common sense. It's a neat trick that makes simple acts like reading an ingredients label seem slightly radical and even fun. I read his stuff and think, "Of course I want to get on board with this. Why wouldn't I?"

Like Maywa, I was dismayed by Pollan's disparagement of "grand schemes" to address climate change. But beyond that, I was struck by the fact that the essay seemed to teeter on the edge of the sort of petty moralism that infects a lot of thinking on this topic. Where was the sense of fun?

If you’re building in L.A., you gotta build green

Los Angeles has become the biggest U.S. city to pass green-building laws. Under the regulations announced Tuesday, new commercial and residential structures of more than 50,000 square feet will have to be LEED certified by the U.S. Green Building Council. The law also applies to major renovations. “We look toward the future through a greener […]

Prez candidates talk up Earth Day, Clinton clinches Pennsylvania primary

Democratic presidential candidate Hillary Clinton won her party’s primary in Pennsylvania Tuesday by a 10-point margin over rival Barack Obama. It’s unclear what role environmental issues played in the Pennsylvania contest, if any, though Pennsylvania is one of many important coal states in the Democratic contest and both Clinton and Obama have regularly touted “clean […]

Interactive poster from German designer

German designer Timm Kekeritz took the "virtual water" data that Sarah posted about from Waterfootprint.org and created this cool interactive poster. We featured Timm's work in the February issue of Seed (not online, but Treehugger wrote about it), which prompted me to order a giant paper version of the double-sided poster. With one side devoted to "footprints of nations" and the other side showing the water "inside" products, this enormous and graphically riveting wall-hanging makes a very cool, if intimidating, addition to any interior décor.

For Nanosolar, the future is municipal solar power plants

The following post is by Earl Killian, guest blogger at Climate Progress.

Traditional photovoltaic (PV) is typically installed on rooftops and competes with retail electricity. Over 40 percent of the cost of a system can be in the installation, which must be customized to every rooftop. So technologies that dramatically lower PV cost end up having a less dramatic impact on total residential system cost. So it is natural that the next generation technologies, such as thin films of copper indium gallium selenide (CIGS) printed as ink on conductive substrates, need to look at non-rooftop applications, where the installation of a large solar farm is fairly turnkey.

Nanosolar, a thin-film PV startup, has just announced their vision in their blog and newsletter. They see the best fit for solar being municipal solar plants of 2-10 MW in size and suggest such plants can be done in 12 months, providing a significant advantage over coal or nuclear. Martin Roscheisen, Nanosolar's CEO, writes:
