Good World Changing Article on saving energy, using technologies we have - some decades old:

The world is ripe with efficiency opportunities. ("The low-hanging fruit," as Lovins puts it, "is mushing up around our ankles.") His Rocky Mountain Institute points out that in industrial settings, "there are abundant opportunities to save 70% to 90% of the energy and cost for lighting, fan, and pump systems; 50% for electric motors; and 60% in areas such as heating, cooling, office equipment, and appliances." In general, up to 75% of the electricity used in the U.S. today could be saved with efficiency measures that cost less than the electricity itself.

The post goes into how the incentives to adopt these measures, just aren't there - energy costs still are a low percent of overall costs, even at 70%.

If this becomes a priority, regulation would have to be adopted, for this to happen.

Apparently, I abandoned the Google Reader for My Yahoo, only a couple of weeks before their change.  The interface has been changed for a month or two now.

That's okay, because that gave them time to deal with bugs and such.  But I must say, the new interface is great.  Easy to mark things as read.  One line previews, or, larger previews.  Easy scrolls to next messages.  Easy to get to the various tags I've added.  More reliable speed.  Easy to tag, email, or share with others.

Very, very nice. 

I've switched again!
