Sent by April Editor: Think of generating your own power as the last step in your approach to saving energy. Step one is conservation. That means CFL or LED bulbs in light fixtures, rethinking the setting on the thermostat (or getting on the phone with building management if you live in one of those buildings that's always way, way too hot). If you've got a really super landlord, perhaps they'll take the plunge and put solar panels up on the roof or, as in the photo to the left, as shading devices for south-facing windows.
If you get your own electric bill, you can call the utility and switch to a greener form of energy. (Not many offer solar power, but most offer a greener option, like wind energy.)
See also this post from Unplggd on solar panels for apartment dwellers.
Any other suggestions for April?
