Hmmm, interesting ideas but I like to read specific solutions like Glenn posted. I have a couple to add.
Get rid of as many electric gadgets as you can. Go to a manual can opener, for example. If you can't do without them, unplug everthing you can when it isn't in use. Obviously I'm not going to unplug my fridge, but the coffee maker, the microwave, cell phone chargers can all be unplugged, saving energy and reducing your expenses.
Get rid of the clothes dryer. Yeah, I know, its hard. I have to plan when I'm going to wash clothes so I know they'll have time to dry on the line. In the winter I have a line on an enclosed porch or I dry stuff over the heater ( adding some nice humidity to my dry winter house).
Drive less. Even if its just a little less, its progress. I drive maybe twice a week, sometimes less. I also bank locally. I work from home, make less and spend a lot less.
Get rid of the cat litter. Yep, I said it. My cats do their business in wood shavings that are a by product of sawmills in my area. Its dirt cheap, its technically a recycled product, has no added chemicals and doesn't pollute.
I wish I had the means to install renewable energy sources at my house, but for now the best I can do is use less and use it carefully.
Gardens are a solution on many levels, the food is more nutritous, seeds cost next to nothing (heirloom plants produce seeds you can save for next year), its a great reducer of stress and good exercise, the food is as local as it gets so no gas was wasted getting it to you.

Thanks for posting your plan of action, its got us thinking about our own solutions.
