The Rise of the Light Emiting Diode (LED)

They are cool.. literally.. you know them by name as well as by sight now.. they set the tone in swanky night spots and they let you know you are in a modern place, the adorn cars looking for street cred as well as those so helplessly geeky they only appeal to the efficiency obsessed. When you were a kid they blinked on your hi fi and on the bridge interments on the Millennium Falcon, and they seemed to last forever and glow on the other side of your TV room a bit evilly when you were trying to fall asleep. They made remote controls possible, saving that tired ass trip to the Zenith to change from the Yankees game to Maverick, and for some reason it took years to go from these simple uses to being basically everywhere, but now they almost are, at a time we need them most...

The Mouse that's Roaring Less and Less: Nicaragua Works for a Green Grid

This will seem funny for me to write about a country that as of now gets more than half of it's energy from from Fossil Fuels ( CIA World Factbook Nicaragua Energy ).. but wait a second.. or a few years, and Iceland and New Zealand might have something to worry about.
I refer to the latter two because they are examples of countries that have put a concerted effort into having Carbon Free National Electrical Grids. From what I know, Iceland, with it's famous Geothermal Plants creating about a quarter of it's grid energy, and a good deal more of it's bragging rights, not to mention one of the world's coolest spas in The Blue Lagoon, the rest coming from hydroelectric dams. As far as I can tell, Iceland is alone in this distinction.

The Expansion of Wind's Power

Somehow Windmills have become the poster child of the Green Revolution..

they are, well, pretty in the abstract, and in person, kind of impressive, form follows function, and they are somehow calming, and like a wind chime, cooling, and they are popping up in large installations it seems just about everywhere (except for the coast of California, but for once I will try not to be grumpy)..the biggest onshore I can find is 5 Gigawatts of potential in north west China, and another in the North Sea might hit 9 Gigawatts.
I can name a few spots I have seen them in my travels. The old famous Farms were the highways east of San Francisco and LA, on 580 and I-10, Altamont and San Gorgonio Pass respectively (the latter also the home of the giant dinosaurs at the truck stop in Pee Wee's Big Adventure, which I know is more important to you than anything that follows). These installations are somehow a vestige of the first Obama administration, known to many as the Carter Administration (or maybe the third Wilson Administration perhaps..), since it was the environmental movement of the 70's that laid the seeds of today's progress, but they lay dormant in some ways for years as we kind of cleaned up many a mess from our wild industrial times before we could step it up to move forward as we are now.

Panama Canal Expansion Project

Due to be done in a few years, and for a while ahead of schedule (no longer at last check), this promises to save a bunch of carbon, and the new gates are more efficient water-wise than the old ones, allowing for less impact on the ecosystem of the Canal Zone, well less than would have happened with the same gate system as the old gates (100 years and ticking!).

the one knock against this, unless you get anarchistic, is that it could have been done with a railroad system, but that might have been even more destructive, as panama would have had to build a huge port on it's pacific side, plus a huge container yard, which might have been more of an eyesore and an environmental catastrophe than just this big construction project.
