Unfortunately, most of us just don't have huge...tracts of land. The solution, however, may soon be within reach with the help of modular wind turbines. While other small wind turbines we've featured have decreased the footprint considerably, these modular turbines can fit just about anywhere, be arranged into any shape, and can pull power from the air even in very low-wind environments. Wind speeds as slow as 2 m/s will start the juice flowing.
The miniturbines are already for sale, but it looks to me like mass production could easily bring down the price considerably (from $150 for 8 miniturbines.) But even now, only one square meter of miniturbines will produce 131 kw/yr in a 5 m/s wind environment. Most houses, though will be able to find quite a bit more than 1 square meter, and in higher wind areas, these little guys could easily shave hundreds off home energy bils with a truly simple and elegant design that won't even disturb the neighbors.
