Here are a few more websites with lots of tips and suggestions:
And a couple of book suggestions:
and Plan B
both by Lester R. Brown (he has a new one out but I haven't read it yet).
Also in the way of cleaning-type-suggestions, I use baking soda and vinegar to clean out drains. Just pour some baking soda down into the drain, and follow it up with vinegar (I don't pre-measure this... just pour enough vinegar to fizz up the baking soda and get it all down the drain. Put in as much baking soda as you like ^_^). It may take a couple of applications if you're really clogged up, but if you do it periodically (preventively instead of after you've already got a clog) it works really well to keep things running smoothly. Also, if you've got a wicked bad clog and even several pours doesn't work, they have these things that you attach to a hose and stuff down into the drain; it builds up water pressure and shoots it in there with so much force that it knocks the clog right out. No harsh plumbing chemicals needed (or expensive plumber bills).
Another friendly alternative I use all the time is for cleaning caked-and-burnt-on pots and pans. While the pot/pan is still hot on the stove (leaving the heat on works best), pour on some lemon or lime juice. The heated up acid will cook off whatever is stuck on your cookware, and you can just scrape it off with a spatula (or what have you) and it comes off like it was nothing. I used to use this when I worked in my college dorm's cafeteria on their industrial-size grills and trust me, if it can clean that mess, it can clean anything. No elbow grease required.
One more tip for water conservation: keep an empty bucket or something by the sink to collect good water that you would normally pour down the drain (for instance, when running the hot faucet waiting for the water to heat up, or cooled water from a hot water bottle, etc). Then use that water to water plants, gardens, lawn, etc.
Hope this was helpful to someone!
