Have some worms over for dinner...

Have you ever thought about how many pounds of food scraps go into your garbage can every week? I never had until we had kids. We were throwing out half eaten sandwiches, half-chewed broccoli, and banana peels like they were going out of style. My wife was watching the Discovery Channel's Planet Green (great channel) and discovered (no pun intended) the power of worms.


Red worms have the power to turn your every day non-protien food scraps into highly enriched compost. According to Washington State University, "worms eat fruit and vegetable scraps, coffee grounds and tea leaves (filter and bags go in, too), grains, pasta, and breads that aren't "polluted." Worm bin pollutants include oils and animal products: meat, fish, butter, cheese, and sauces. "

The best type of worm condo is an enclosed worm box. This contraption was quite new to me a few weeks ago, but basically it is a box, with some organic brown matter (soil, grass clippings, etc.), red worms, and your daily food scraps. It is important to note that a tightly fitting lid is necessary to keep rodents & bugs at bay.


Usually wooden boxes made of plywood are used. If you are using a plastic bin, be sure to add both drainage and aeration holes. Never use a container which has been used for storing toxic chemicals. Start by putting bedding in the worm box. Corrugated cardboard, news-print and newspapers shredded in strips four inches long by 1 inch wide make excellent bedding. The worms need some grit for breaking down their food. Add a little topsoil for this purpose. Put the worms on top of the bedding.
In you'll be on vacation, just feed the worms a bit extra and leave them undisturbed until you return. Obviously there can be a population control issue with multiplying organisms eating all your food scraps. Red worms double in population approximately every three months. At that time, you can sell your worms to another earth-minded individual, or go fishing! Trout love red worms!!!

Going Green Off The Grid

"Zero Energy Building" and "Going Off The Grid"; expect to hear those phrases more and more frequently.

But what do they mean and are they the same thing?
According to Wikipedia:

"Zero Energy Buildings" (ZEBs), at least in the United States, are when the amount of energy provided by on-site sources is equal to the amount of energy used by the building. They are still connected to an off-site energy source and sometimes sell energy back to the utility company.

"Off The Grid" buildings are stand-alone ZEBs - not connected to an off-site energy utility facility. They require distributed renewable energy generation and energy storage capability.

Either way owning a building with a net energy consumption of zero over a typical year would be nice. Imagine not only having your home paid for by the time you retire, but also having your utilities paid for...it would make those senior years a little easier to enjoy.

Doug Rempel in Canada is building his home with this in mind. Visit his blog and see how Enercept structural insulated roof panels are playing a key role in his new home: http://goinggreenoffthegrid.wordpress.com/
