Of course you want to cut energy costs and use less water, and you're tired of all the same old ideas -- aside from showering with someone else (but that doesn't really save water, does it?).

As National Cut Your Energy Costs Day approaches, we thought you should see some of the more cutting-edge (or bizarre) methods to shave pennies from your utility bills, help save the planet and look like a freak doing it. Think carpeting your fridge or the art of dumpster diving are strictly for hippies? Think again.

Crazy Ways to Cut Energy Costs

    Grass Roofing: If you're interested in gardening but have no yard space you can still consider a green roof. The idea is plant hardy grasses in 2-4 inches of soil. This reduces storm runoff, which will ultimately lower your sewer bill. It'll help cool down the building and prolong the roof's life.

    Moo-based Methane: If we're going to eat beef, from an animal considered to be the most wasteful to produce (aside from humans) we might as well capture its capacious methane gas explosions for energy usage. You really wouldn't want to be the meter reader for that job.

    Worm Disposal: If you don't have a green thumb, you might go in the other direction: grow your own worms. From garbage. It can be done indoors (a plus). All you need is 2,000 worms to eat a pound of food waste every day. This means less garbage gets driven to the landfill and more bait for fishing.
