Recently the Emergency Economic Stabilization Act of 2008, H.R. 1424, was passed by Congress that includes a new federal investment tax credit to assist the public in offsetting the wind turbine cost for their homes, businesses or farms.  Without any delay, president Bush signed the bill into law.

The Act offers a federal tax credit for 30% of the total installed cost of any wind power system with a 100 kilowatt capacity or less, but the credit will not exceed $4,000. The limitation of the Act is that it only applies to new systems installed from 3 October 2008 through to December 2016, so any current systems will get no tax relief.  In addition, for home wind turbines, the credit is further limited to the lesser of $4,000 or $1,000 per kW of capacity.
