Why invest in your own windturbine?
There are many good reasons to invest in your own electricity producing wind turbine.
One reason is of course that the price per produced kilowatt hour (kWh) is lower than any other alternative, including solar panels.
Unlike solar panels, a wind turbine will produce energy both day and night.
Also, in cold climates, most of the energy is produced at the time of the year, when you most need it.
Our goal is to produce electricity for less than $ 0.1 per kWh, when you write down the investment during a ten year period.
Other benefits are independence from fluctuating energy cost and emission free energy.
With more Electrical Vehicles (EV’s) and even electrical tractors, one can produce food with less impact from fossil fuels.
We achieved this by refining the Vertical Axle Wind Turbine (VAWT) type: Darrieus H-design, with only one rotating part and laminated wood wingprofiles.
These VAWT H-designs are suitable for windturbines up to the size of 16m2 intercepted / swept area (4.5 meters high x 3.5 meter in diameter).
Beyond 16m2, wood propellers still will be more economical and ecological friendly than fiberglass, using the conventional Horizontal Axle Wind Turbine (HAWT) for sizes up to 500m2 (25 meter in diameter).
Wood store large amounts of CO2 from the atmosphere. Combined with new technology the lifetime will outperform other contruction materials.
To prove my point: Here in my home country Norway, we still have old wooden churches, called “stav kirke”, which are still in use.
The oldest wooden church: Urnes stavkirke was built in year 1130 and some of the timber still in use was cut in year 1060 to 1070.
