Scott, I love your enthusiasm! I wish changing the world was as easy as writing an optimistic blog post. I wish the optimism and simplicity of it all was more lasting, from my perspective, too. 

Jennifer, yes, I've actually written about LEED certification and renewable energy quite a bit for various clients. It's definitely true that LEED certification does not ensure an efficient home, even though many people assume that it does. That's why it's important to combine a variety of approaches to being green. The Habitat organization I wrote about is doing just that, to make sure the homes are energy efficient and cost less for the home owners to heat and cool.

Daisy, that's when it gets exciting, isn't it—when you see how someone's basic needs to survive can be taken a step further, toward their basic constitutional right to thrive.
