Renewable energy systems are exempt from property taxes in Alaska, thanks to 2010 CFK winner Freya Chay.

In 2010, Freya won the contest as a freshman at KCHS with her idea to create a property tax exemption for renewable energy systems. Freya brought her idea to local lawmakers as a Legislative amendment, which was signed into law by Governor Sean Parnell just a few weeks after Freya won CFK.
