Q: I’m buying a new laptop, and I was wondering if all computers are the same energy-wise, or if some brands are better for the environment?

Q: I’m in the market to buy a new couch (our current one is older than I am-it’s 27!). Is it better to buy a “green” couch, one from a mainstream vendor or a used couch? If used is the way to go, do you have any suggestions for finding one that isn’t disgusting?
