Turning My Home Zero Energy For $48K In Portland, OR

When Ryan Shanahan bought his home in Portland, OR in 2014, he dreamed of turning it into a net-zero house--one that would produce at least as much energy as it consumed in the course of a year. But retrofitting an over one-hundred-year-old structure into a eco-friendly building seemed like too much to hope for. But by 2020, he and his wife, Megan Milligan, had fully converted their home to net-zero, producing so much solar energy that their yearly electricity bill dropped from $1,100 to $285.
