Seven years ago, the Danish island of Samso became the first island to use renewable energy for 100 percent of its electricity needs. Now, Samso's farming communities are moving toward organic farming – and away from fossil fuels.
The Obama administration issued new support for offshore wind power projects this week as part of the president's Climate Action Plan. While land-based wind power has expanded in recent years, the renewable energy source has struggled to gain hold off the coasts.
On May 11, there was enough sunshine and wind in Germany to meet 75 percent of the country's demand for energy. It was also enough to cause Germany's price of electricity to cost practically nothing for an hour.
Most of us think of ammonia as a pungent household cleaning agent that disinfects and deodorizes, Cobb writes, but ammonia can also be used as a carbon-free, relatively safe form of fuel.
New research suggests offshore wind turbines can absorb significant energy from hurricanes, reducing winds, waves, and storm surge.
