Maybe you took my previous post on conspicuous consumption to heart, and you’re trying to use every last kilowatt-hour efficiently...but you’ve been beset with efficiency-related ennui. The programmable thermostat aisle at the hardware store just doesn’t excite you like it used to. You’re ready for something new—not just using energy efficiently, but producing that energy yourself from renewable sources. In short, you’re thinking about home wind turbines or solar panels. But where to start?
Considering wind turbines? First, explore the wind resource in your area. While it’s true that the wind blows everywhere, wind resources can vary widely depending on structures, trees, or landscape features. Broad overviews of U.S. and state wind resources are available, but you’ll probably want explore the wind resource at your site more closely. Tools like In My Backyard from the National Renewable Energy Laboratory can give you a more detailed idea of your particular resource.
Exploring available wind turbines is your next step, so you can get a handle on how much purchasing and installing said wind turbines will cost. Organizations like the American Wind Energy Association (AWEA) offer lists of wind turbine equipment providers, as well as suggestions on the type of questions to ask providers. You’ll want to consider any local, state, or federal incentives for wind turbines or small wind systems that might reduce overall system cost, and make sure the wind turbine you are considering qualifies. When considering wind turbine options, think carefully before you decide on a roof-mounted wind system (or "urban turbine"). While roof wind turbines and similar systems are currently popular, they have a number of drawbacks that may not make them right for your renewable energy needs.
Next, will your wind turbine will be grid-connected or stand alone? This decision will influence the type of equipment you need. If you choose to connect your wind turbine system to the utility grid, you’ll likely want to explore whether net metering (receiving credit from your utility provider for excess power you produce) is available in your state.
Finally, explore any state or local codes or ordinances that might affect your proposed wind turbine installation. Your homeowner’s association, local building codes official, and local government are good contacts as you explore laws or requirements your proposed wind system may have to adhere to.
Sound too complicated? A couple of good guides will walk you through the process. Check out Small Wind Electric Systems: A U.S. Consumer’s Guide from the Department of Energy or the AWEA’s Small Wind Communications Toolbox. Additionally, many states have developed Wind Working Groups in conjunction with the Department of Energy’s Wind Powering America program. Your state’s Wind Working Group is a great source for state-specific information related to wind development.
