Read your GG book last week - loved it! I was surprised how green I already am in some areas AND how much I'm not in others.
In my kitchen, I use CFL bulbs. I've replaced many plastic storage containers with glass. I use Corningware in oven and microwave and have Visions for stovetop so I can see what water is doing without removing lids. Since the early 80's I've used the microware to cook as much as possible instead of electric range & oven.
I take my trash bin for pick-up only every 2-3 weeks, but recycle goes out weekly. Here they take all plastics plus milk, cream and juice boxes. They probably ship it all somewhere for processing; not too much "landfill" on Gulf Coast -- too close to sea level!
After reading book, I went to Whole Foods and was nearly overwhelmed by all the stuff available! I'd only been there once when it opened because it's on the other side of town and they don't carry my "regular stuff!" Now I know why!

I will be making the trip more often now.

There is a "farmer's market" downtown every Sat morning - early! I'm not a perky morning person, so I haven't ever been there. Now if it was open between 12 & 2 am....
I'm getting rid of Red Alert products and gave all my Orange List stuff to my daughter. She has kids and will use them up faster than I will. It will take some time to get her "on board" with changes since my dear son-in-law does all the shopping!
I have only one complaint about conserving our natural resources -- money. I have taken my water usage down to the minimum measure of 100 cu ft since I live alone (with 2 pets) BUT I must still pay for 400 cu ft every month! My non-conservative side says "why not use it if I have to pay for it anyway?" I wish somehow I could save all that "extra" water for the dry summer months when I must water the garden! Will our suppliers ever reward use for our conservation efforts?
My natural gas usage is limited to winter heating and water heater. Everything else is electric. Finding more ways to conserve there is an ongoing project.
