"Kayaktivists" demonstrate in Seattle's Elliot Bay against the arrival last month of the Shell's massive Polar Pioneer oil rig, rising behind them above the city's waterfront. Shell is using Seattle as a staging area for its new offshore drilling operatio
President Obama has given Shell the green light to drill for oil in the Arctic Ocean, but activists and politicians in Seattle are throwing up as many stop signs as they can as the drilling rig preps there for its journey north. It's the latest flashpoint in the growing international anti-fossil fuel movement.
A bee approaches a peach blossom. Many of the more than 20,000 species of bee worldwide, including the well-known honey bee, are threatened by disease, habitat loss, and pesticides. President Obama's national pollinator plan would provide incentives for r
Honey bees and other pollinators are in big trouble. President Barack Obama wants to help save them with a new protected bee habitat corridor along I-35 spanning the US from Laredo, Texas to Duluth Minnesota. Catherine Winter, who lives in Duluth and keeps bees herself, tracked down some other bee enthusiasts to talk about the president's plan and their own efforts to protect the pollinators that help feed us all.

Lutz Wiese of Vattenfall power company refuels a hydrogen-powered Mercedes at a filling station in Berlin. Vatenfall is a partner in the world's first direct wind-hydrogen power plant, in northern Germany. Using wind-generated electricity to create hydrog
How do you balance the ebbs and flows of wind and solar power to use it when and where it's most needed? Turn it into hydrogen and use it to drive cars.
A surge in wind turbines like these have helped Germany generate more than 25% of its electricity from renewable sources. Since Germany's electricity system is interconnected with most of the rest of western Europe, the overall percentage of this kind of
Too much renewable power? A German engineer comes up with a way to store excess renewable energy, take pressure off the grid and ease the way for the adoption of more wind and solar power in a country that's already way ahead of most of the rest of us.
Solar power production has grown more than 25 times over the last decade in Germany, spurred largely by big incentives for small producers to get into the market. But sunshine and wind power are intermittent, so engineers and others are looking for ways t
Unhappy with the economics of his rooftop solar panels, a German tinkerer invents his own electricity storage system that saves users hundres of dollars a year, makes it easier to integrate renewables into the grid, and wins an award for renewable product of the year.
