Wind power companies are taking a bird’s eye view in siting new turbines in the Altamont Pass.As a major re-powering effort gets underway to replace 50-year-old windmills with fewer and larger ones, the companies are making use of new techniques in risk mapping to avoid the numbers of raptor deaths that have become part of the political fabric of the Altamont Wind Resource Area.
It’s showtime. What better way to spend a blustery day in early March than to visit the two green film festivals in San Francisco? This year’s line-up features a number of films from Bay Area filmmakers and ones that touch on local topics. Among them is Bay Area filmmaker Jon Shenk’s “The Island President” about how the recently ousted leader of the Maldives, Mohamed Nasheed, is trying to save his country from being the first obliterated by sea level rise. In an interview, Shenk explains why all coastal cities — including Bay Area cities — should take what’s happening in the Maldives to heart.
The cash-strapped city of Benicia has come up with a novel way to keep its local state recreation area open and off the list of California park closures: get the state to foot the bill. The city says it can operate the 500-acre park at less than half the state’s budget.

When Europeans arrived at what is now Pinnacles National Monument, the land was not exactly a “pristine” or “untouched” vision of nature, but rather a managed ecosystem that itself had become dependent on fires set by the Amah Mutsun Tribal Band. Scientists are studying the traditional fire practices to help the ecosystem build greater resilience to major disturbances like climate change.
The Beach Chalet Athletic Fields may not seem like an ecological oasis, but environmentalists are fighting a San Francisco plan to replace natural grass with artificial turf. They say the move would turn foraging grounds into the ecological equivalent of a parking lot. City officials say the fake grass is needed to help it meet growing recreational needs.
Four surfboard-sized vehicles set sail off the coast of the San Francisco Bay on Thursday in an attempt to break world records in ocean exploration and robotics. The “wave gliders” will, if successful, traverse the longest distance of any unmanned ocean craft as they cross the Pacific Ocean.
Environmental groups have filed suit against the city of San Francisco under claims it’s violating the Endangered Species Act at Sharp Park Golf Course.
