The penetration of renewable energy into the electricity supply mix has been much in the news recently. During the first quarter, Portugal generated three-quarters of its electricity with renewable energy. Meanwhile, in Germany, one-fifth of all electricity was generated with renewables, most of that from new sources of renewable energy, such as wind and solar. And recently, at a conference in San Francisco, attendees heard calls for generating not just 100 percent of electricity supply with renewable energy, but far more — 200 percent to 300 percent of generation — in order to meet the need for heating, cooling, and transportation as well.
A Seattle-area company developed the wind turbines Majel Dixon is talking about. They’re called Powersails. The blades look more like a sail from a sailboat than the traditional propeller-like blades seen at wind farms.
About a dozen Republican legislators met on the steps of the state Capitol on Thursday to call for a veto on the rural renewable energy bill, arguing that it, along with gun-control bills passed earlier this year, are an attack on rural Colorado
The U.S. Army has just launched the first in a series of renewable energy contracts that will eventually total $7 billion by the end of this year, using power purchase agreements along with a standard procurement tool that is expected to crush any obstacles that are put in its path. That includes the notorious budget sequester as well as any objections from the anti-renewable energy crowd in Congress, which has already used the budget as an excuse to sink the Navy’s biofuel initiatives.
