The first X-Class solar flare of the year went off yesterday, on March 7th, in spectacular fashion. Fortunately the flare went off where it's supposed to: on the Sun. Had this intense magneto-plasmic explosion gone off on Earth, we'd be toast; one of these releases an amount of energy on the order of 100 billion megatons of TNT.
A solar flare, associated with the big sunspot numbered 1402, erupted on January 23rd, launching a coronal mass ejection–a "cantaloupe" of plasma that makes Earth look like a grape. Rated as an M9-class flare, it packed umph just shy of what's necessary for adult "X-class" flaredom, the most powerful kind.
Energy storage (through batteries) is something we use everyday in our cell phones and computers. So it may be a little surprising that when it comes to the electric grid, storing energy is something that's rarely done.
Between the aquarium of drowning-delegate sea-level rise protesters, the chicken flock of animal rights protesters, and the cocktail party of fur-coated protest protesters, there will certainly have been a lot to see these past two weeks in Copenhagen during the latest United Nations Framework Convention on Climate Change (UNFCCC).
Since people seem to nod off a bit when I say I'm working on a story about energy efficiency, I've had to re-tool my pitch. "It's a story about how installing solar panels or a wind turbine is the last thing you should do to green your house," I say, perhaps a little over-dramatically.

First of all, "lineups," or alignments, go on in the heavens all the time, though most often they are alignments of objects too faint to easily […]

In Silicon Valley, a battle between neighbors has turned into a different kind of face off: solar energy versus trees. It turns out that growing redwood trees can actually be a crime in California, if they block solar panels… as one couple in Sunnyvale found out the hard way. David Gorn reports on a new […]
If investment is any guide, California's renewable energy companies are leaping into the new year. Investors poured billions of dollars into clean tech in 2007 to catapult green technologies to market. In the first three quarters of 2007, U.S. venture capital firms invested $2.6 billion in clean tech companies. That's compared with $1.8 billion for […]
