We've got a couple of good questions that have shown up in the Discussion Forum over the past day:

1) GO member attacat asks about using biodegradable trash bags/bin liners:

The bin liners that are commonly used are made of synthetic polymers like polyethylene and polypropylene, and these are not considered biodegradable. Eventually, these plastics will break down, but only after being submitted to decades of heat and light.

Green Your Office proposes a new technology called d2w totally degradable plastics. Apparently, these refuse sacks will “degrade turning harmlessly into CO2 and water”. I may be missing something here, but isn’t CO2 one of the main gases that the greenhouse effect has been blamed on? Are biodegradable bin liners actually harmful to the environment as well?

Got an answer to this one? Is the amount of CO2 produced by these products negligible when compared to the impact of plastic?

2) GO member tamilee is likely not the only person with this question:

Where can I find home solar power systems and how they work explained in the simplest terms possible? I'm looking for a solar power for dummies website or book. I have been interested in solar power for decades but whenever I try to learn about it there is so much jargon used I just get lost.

There is a Complete Idiot's Guide to Solar Power to Your Home; the second edition will be released in May. Any thoughts on this book, or other recommendations?

As always, please answer these questions in forum where they were posted…
