When Studio 804 completed the Springfield house two years ago next month, one of the things that I really liked about the home was the vertical wind turbine in the back yard. I liked the idea, of having something that reduced my carbon footprint, used green energy, and put electricity back into the grid when possible.
Last night when I was sitting on the back deck behind my house, I kept thinking we should go for it and install the same kind of wind turbine. We have more than enough yard space, and while it might be expensive the environmental impact and long-term cost savings out weigh the initial up front costs.
The unit at the Springfield house is manufactured by Windspire, and is designed to generate clean renewable energy and help offset your overall energy use. The residential unit stands 30 feet tall and is designed to fit within urban areas. The size and height of the unit, would be completely invisible from the street if I placed it about 50 feet behind my house in our field. The Windspire generates 2000 kWh of energy per year with winds as low as 8.5 miles per hour. This sounds perfect for us.
The residential unit requires a small foundation of 2 feet by 7 feet in size, and is virtually silent with an audible noise level of 6dBA in a 15 mile per hour wind. And since the Windspire rotates at lower speeds than most turbines it is more visible to flying birds. (I don’t want to install anything that might take out the songbirds in my yard.) The Windspire really looks amazing in really life. Like a kinetic piece of sculpture, with a satin silver finish. When I first saw it at the Springfield house I really thought it was a sculpture, not a wind turbine. That is a definite plus as far as I am concerned.
Right now U.S. homeowners are eligible for a 30% federal tax credit off the total cost of the turbines including the installation and available local rebates as much as $4,800 in some states.
