I was looking and home wind options last weekend, and came across Harmony Wind Turbines, which look interesting given as a vertical solution they take less room, their models apparently can gather wind at lower wind speeds, and they have a feature to allow they to function at higher wind speeds, increasing the total operational speeds. Unfortunately, all the interesting details are pending testing which they've partnered with universities for, but I'm not sure how far along they are. Its unfortunately very hard to yell whether it's actually interesting or just appears to be so because key details aren't known, but hopefully we'll know one way or another within a year or two. The other energy source that's drawn my interest recently is microhydro solutions, but that necessarily requires specific geographic features (a water source and elevation).
