Are solar cell panels and wind mills worth the money?
Although this isn't related to homes directly, as an IT professional I know that wind power tends to be cost effective to the point that many data centers (the massive buildings holding the servers that are the backbone of the internet) actually invest in their own wind turbines to slash costs since servers tend to be power hogs. As far as going "off the grid" that ultimately depends on how much wind/sun you're getting at your residence, but if you look at places like Dallas, PA, CA, and other areas where  the major hosts place centers, they're typically in areas where there's plenty of sunlight or wind. Going back to small scale thinking however, one of my contacts actually leases a colocation building in PA where he has a few server racks, and while he currently has electric there, he also owns a couple of turbines which have been powering <60% of the demand, and he's actually planning to add solar and also feed that back to the grid at a profit. So overall wind/solar definitely has the potential for a decent ROI, at both large and small levels, but performance will vary greatly from area to area.  I know that Lowes actually started advertising about carrying solar panels, so going in and asking about the performance and if you can arrange an audit of your home might be a good place to start. If you Google "green audits" I'm sure you can find a trillion companies "specializing" in green power, but as with any sales rep (including at Lowe's) I'd do some due-diligence so you don't get taken for a ride, and also to check references because I don't think "green audit" companies have any official certifications/standards.
