Maya House,
Go solar and use wind as a back up only. We do not have enough constant wind to make a turbine worth the expense, especially if you already have BEL. Plus any turbine large enough to generate any kind of wattage will have to be on a 30' pole above the house and tree line to avoid turbulence. They are not silent either. You will need batteries for storage or the power will only be available when it is being actively generated. Storage is always the issue for homes or power plants.
Check with Customs Department about a special duty on solar. When we brought in our turbine and a set of batteries last year, we were told if we had 1 solar panel we could have qualified for a discounted duty on a "solar system".
Our panels, small turbine and 16 dry cell batteries run our entire house. We have no plans to hook up to BEL when they get to our neighborhood.
Good luck!
